Breeding soybeans for the tropics capable of nodulating effectively with indigenous Rhizobium spp., Kueneman, E., Root, W. R., Dashiell, K. and Hohenberg, J., in: Plant and Soil, volume 82, number 3, pages 387-396, 1984. [DOI]
 
Abstract:
Most soybean varieties fail to nodulate effectively in tropical soils unless inoculated with a competitive strain of Rhizobium japonicum. Developing countries in the tropics, with few exceptions, lack inoculant industries to produce and distribute viable inoculants to small farmers and extension programs to teach them to use inoculant. Several soybean genotypes have been identified that nodulate effectively with many strains of the cowpea inoculation group which is ubiquitous in tropical soils of Africa. Soybean genotypes that nodulate and grow well without inoculant application are called promiscuous. Methodologies for incorporation of the promiscuity character into high-yielding backgrounds are discussed.

Hartmann Cassava is well recognized for its capacity to address food needs of vulnerable communities in unstable environments in SSA. IITA and colleagues in African NARS, in collaboration with CIAT and ARIs have played leading roles in the development of improved cassava varieties which are disease and pest resistant, early maturing, and high yielding. Through a combination of conventional and new approaches, over 400 cassava genotypes have been developed. The characteristics of the new generation of cassava germplasm broke what had been an apparent yield barrier in cassava improvement increasing yields in many locations by at least 50-100% without the use of fertilizer. The improved germplasm is shared with NARS within the region as specific genotypes or improved seed populations for evaluation and selection under local conditions. Improvement programs in Africa that received these materials have tested them under local conditions, selected varieties that outperform local varieties, and released them to farmers in virtually every major cassava producing country. Today, about 30% of the area cropped with cassava in Africa is planted with improved varieties. Without the introduction of more productive cultivars with multiple diseases and pest resistance, the effective biological control of the cassava mealybug and, to a certain extent, of the green mite, cassava production in SSA would be 50% or less of what it is today. That translates to over 13 million tons of dry cassava/year, enough to meet the calorie requirements of 65 million people. The significant gains in the crop's output in farmers' fields are not only contributing to the African diet but also propelling commercialization of the crop. This paper highlights contributions to cassava improvement in SSA since 1970 by IITA and its partners, and suggests areas needing strengthening in the drive to produce better crop varieties for different regions and enduses in Africa.

Characterisation of resistance in cassava against viruses causing cassava mosaic and cassava brown streak disease in Africa, Koerbler, M., Stein, B., Ingelbrecht, I., Dixon, A. and Winter, S., 2008.
 
Abstract:
Cassava mosaic disease caused by diverse geminiviruses (CMG) and Cassava brown streak disease caused by cassava brown streak virus (CBSV), are key constraints to the cultivation of cassava in Sub-Sahara Africa. We have collected and characterised the diversity of the most prominent geminiviruses from all African cassava cultivation areas and Cassava brown streak viruses from East Africa, to use defined viruses for resistance studies in selected IITA cassava breeding lines and African land races. Virus infections were established in cassava by either graft inoculation with scions of virus infected plants or, by particle bombardment of cloned infectious viruses. Resistance against cassava mosaic geminiviruses was identified in several breeding lines e.g. TME 4, TMS 96/0529 and TMS 96/0160 responding with abortion of virus infections after virus introduction. Other genotypes, e.g. TMS 96/0304, became infected but recovered from symptoms but maintaining the infection status. When cassava clones were analysed for CBSV resistance, it became evident that geminivirus resistance was tightly correlated with susceptibility against CBSV. Geminivirus resistant cassava responded with often severe CBSV infections (e.g. TMS 96/0160) upon virus inoculation. Interestingly, cassava genotypes with an intermediate resistance, TMS 96/0304, initially became mixed infected with CBSV/CMG however subsequently aborting CMG, to establish single CBSV infections. Differential responses were also recorded for strains of CBSV. While CMG resistance in cassava was against all CMG, differential responses were observed in cassava inoculated with CBSV isolates obtained from Kenya and Mozambique. While the CMG susceptible cassava landrace TME 117 was resistant against CBSV from Kenya, it became infected with CBSV from Mozambique. Only the cassava genotype TMS/ 1089A revealed immunity against CMG and also did not establish infections with the CBSV isolates from diverse origins.

Fruit characteristics and ripening pattern of ten Musa genotypes in a sub-humid environment in Nigeria, Baiyeri, K. and Tenkouano, A., in: Fruits, volume 63, number 1, pages 3-9, 2008.
 
Abstract:
Introduction. Conventional evaluation of Musa through multilocation trials has often been carried out to ascertain the yield stability and ecological range of new varieties but, for prospective growers, it is equally important to know the fruit characteristics and ripening pattern of the genotypes. Indeed, fruit characteristics determine consumers' attitudes towards the new varieties, and the associated market value of these varieties. Materials and methods. The metric traits and ripening pattern of fruits from nine Musa hybrids and one local variety of plantain were evaluated during two cropping seasons in a sub-humid environment in Nigeria. Results. All the traits measured varied with the genotype, but cropping cycle influenced only fruit weight and days to complete senescence of fruits. The interaction between genotype and cropping cycle was significant on fruit weight, fruit length and days to attain four different ripening stages. Most genotypes had better values in the ratoon harvest than in the plant crop. Fruit length and shape of PITA 21 were comparable with those of the local check, but the index of edible proportion was highest in PITA 22. PITA 21 and PITA 26 had the longest green life and total shelf life. Conclusion. The genotypes evaluated in our study revealed different utilization potentials. Also, the better postharvest life of some of the hybrids and comparable metric traits with the local check suggested the high adoption potential of the hybrids.

Genetic transformation of cassava - independent of genotype, Jorgensen, K., Ingelbrecht, I., Jensen, S., Olsen, E., Sorensen, C., Kannangara, R. and Moller, B., 2008.
 
Abstract:
Cassava is a vegetatively propagated crop and its improvement through conventional breeding is challenging due to its high heterozygosity and low fertility. As it has not been possible to solve all cassava's problems connected to agriculture and consumption by traditional breeding, another solution could be to use molecular breeding. Major deficits of cassava are low protein content in the tubers, rapid post-harvest tuber deterioration and high content of cyanogenic glucosides. Careful processing of cassava roots is required to remove the released hydrogen cyanide which can cause acute or chronic cyanide intoxication. Unfortunately, processing to remove hydrogen cyanide typically results in loss of protein, minerals, and vitamins. For successfull molecular breeding of cassava, a genotype-independent genetic transformation method is essential. So far it has only been possible to transform model lines which have limited agricultural importance. Here a regeneration and transformation method is presented which has been successfully applied to all African varieties tested so far with a transformation frequency ranging from 0.2% to 3.8%. The method is based on the procedure developed by Li et al. (1996). This method is among others now used to 1) produce acyanogenic cassava (J{\o}rgensen et al 2005), 2) improve the nutritional value in the tubers, 3) virus resistance. The improvement of the nutritional value is focused on increasing the protein content in the tubers in varieties with and without a naturally increased levels of pro-vitamin A.

Highly client-oriented breeding with farmer participation in the Ethiopian cereal tef (Eragrostis tef (Zucc.) Trotter), Tefera, H., Belay, G.*, Assefa, K.* and Metaferia, G.*, in: African Journal of Agricultural Research, volume 3, number 1, pages 022-028, 2008.
 
Abstract:
This paper describes a highly client-oriented breeding applied to enhance the development and release of a tef (Eragrostis tef) variety with farmer participation in Ethiopia. The main features include; clear objective, target cross, early-stage researcher selection, multi-location yield trial, farmer on-station selection, judicious selection of few candidate varieties based on farmers' and researchers' selections, farmer managed on-farm trials, and release through the existing formal procedure. In the application of this strategy, tef exemplifies a crop with local importance, a clear market-driven selection criterion (cash crop) and farmers have better judgment of the criterion than researchers. Using farmers' consistent selection of genotypes, in conjunction with the required quantifiable data, breeders were able to release a new tef variety named ''Quncho''. The new variety was not the highest yielder, but it was higher in grain yield and better in seed-color quality (very white seed-color) than the long-time cultivated variety DZ-01-196 (Magna), which was used as quality check. Given the appropriate degree of client-orientation, the results also show how farmer participation and formal breeding programs complement each other so as to overcome the rather prohibitive variety release procedures based on data from participatory breeding alone.

Identification and validation of EST-derived microsatellites for genome analyses of cassava (Manihot esculenta Crantz) and related taxa in the Euphorbiaceae, Raji, A., Kolade, O., Anderson, J., Ugwu, C. D., Gedil, M., Dixon, A. and Ingelbrecht, I., 2008.
 
Abstract:
Using bioformatics tools, we identified 646 Simple Sequence Repeats (SSRs) in silico from a unigene set of 8,577 Expressed Sequence Tags (ESTs) in cassava for the development of genic microsatellite markers. A total of 346 primer pairs were designed. Of these, 96 primer pairs were tested for polymorphism among diverse, cultivated genotypes of cassava (M. esculenta) from Africa and South America and three wild species. The cassava array comprised landraces as well as elite lines, five of which have previously been used as parents of mapping populations. Ninety percent of the primers amplified DNA fragments. Candidate EST-SSRs were analyzed on high resolution agarose gels and on ABI 3100 Genetic Analyzer. The number of alleles ranged from 1 to 8 which is lower compared to microsatellites derived from genomic sources. Approximately 80% of the microsatellites detected only one or two alleles per accession indicating a low degree of duplicated loci, a surprising finding for a highly heterozygous species such as cassava. Several markers showed cross-genus amplification across castor bean (Ricinus communis) and leafy spurge (Euphorbia esula), thus showing transferability from cassava to other taxa of the Euphorbiaceae. This study provides an in-depth view of the frequency of microsatellites in the cassava transcriptome, demonstrates the successful development of genic SSRs, and also indicates that available EST and genomic resources of leafy spurge and castor bean can be utilized for microsatellite marker development in cassava.

Identifying aflatoxin resistance-related proteins/genes through proteomics and RNAi gene silencing, Chen, Z. Y., Brown, R., Guo, B. Z., Menkir, A. and Cleveland, T. E., in: Peanut Science, volume 36, number 1, pages 35-41, ISSN 0095-3679, 2009.
 
Abstract:
Aflatoxins are carcinogenic secondary metabolites produced mainly by Aspergillus flavus Link ex. Fries, and A. prarasiticus Speare during infection of susceptible crops, such as maize, cottonseed, peanuts and tree nuts. This paper will review research efforts in identifying aflatoxin resistance-related proteins/genes in maize. Similar strategies may be useful in peanut. For maize, although genotypes resistant to A. flavus infection or aflatoxin production have been identified, the incorporation of resistance into commercial lines has been slow due to the lack of selectable markers and poor understanding of host resistance mechanisms. Recently, resistance-associated proteins (RAPs) were identified through proteomic comparison of constitutive protein profiles between resistant and susceptible maize genotypes. These proteins belong to three major groups based on their peptide sequence homologies: storage proteins, stress-related proteins, and antifungal proteins. Preliminary characterization of some of these RAPs suggest that they play a direct role in host resistance, such as pathogenesis-related protein 10 (PR10), or an indirect role, such as glyoxalase I (GLX I), through enhancing the host stress tolerance. To verify whether these RAPs play a role in host resistance, RNA interference (RNAi) gene silencing technique was used to silence the expression of these genes in maize. RNAi vectors (glx I RNAi and pr10 RNAi) were constructed using Gateway technology, and then transformed into immature maize embryos using both bombardment and Agrobacterium infection. The extent of gene silencing in transgenic callus tissues ranged from 20% to over 99%. The RNAi silenced transgenic maize seeds have also been obtained from plants regenerated from Agrobacterium transformed callus lines. Kernel screen assay of the transgenic maize kernels demonstrated a significant increase in susceptibility to A. flavus colonization and aflatoxin production in some of the silenced transgenic lines compared with non-silenced control kernels, suggesting the direct involvement of these two proteins in aflatoxin resistance in maize.

Novel sources of resistance to Fusarium stalk rot of maize in tropical Africa, Afolabi, C., Ojiambo, P., Ekpo, E.*, Menkir, A. and Bandyopadhyay, R., in: Plant Disease, volume 92, number 5, pages 772-780, ISSN 0191-2917, 2008.
 
Abstract:
Fusarium stalk rot is one of the most widespread and destructive diseases of maize, and deployment of resistant genotypes is one of the most effective strategies for controlling the disease. Fifty inbred lines and four checks from the breeding program of the International Institute of Tropical Agriculture were evaluated in field trials at Ikenne and Ibadan, Nigeria in 2003 and 2004 to identify new sources of resistance to stalk rot caused by Fusarium verticillioides. Evaluations were conducted under artificial inoculation and natural infection at Ibadan and Ikenne, respectively. Disease severity was recorded using a severity scale (SS) and direct estimation of stalk discoloration (SD). The two methods of disease assessment were compared and combined to classify genotypes into resistance groups using results from rank-sum analysis. In 2003, disease severity ranged from SS = 1 to 5 and SD = 1.3 to 33.8% at both locations. Both SS and SD were significantly (P < 0.01) higher in 2003 than in 2004 at the two locations. In both years, inbred lines significantly differed in SS (P < 0.02) and SD (P < 0.04) at Ibadan. Similarly, inbred lines significantly differed in SS (P < 0.04) and SD (P < 0.04) when genotypes were evaluated at Ikenne. Disease assessments based on SS and SD were significantly correlated (0.68 < r < 0.95, P < 0.01) in both years. Based on the results from rank-sum analysis, inbred lines were separated into highly resistant, resistant, moderately resistant, moderately susceptible, susceptible, and highly susceptible groups. At Ibadan, 6 (11.1%) and 8 (14.8%) were identified as highly resistant and resistant, respectively, whereas 11 (20.4%) were identified as resistant at Ikenne. Inbred lines 02C14609, 02C14643, 02C14654, and 02C14678 were consistently classified as either highly resistant or resistant to stalk rot across locations and years while the check genotypes were classified either as susceptible or moderately susceptible to stalk rot. These four inbred lines identified to have high levels of disease resistance may be used for breeding maize with resistance to Fusarium stalk rot.

Severity of anthracnose and virus diseases of water yam (dioscorea alata L.) in NIgeria I: effects of yam genotype and date of planting, Egesi, C. N.*, Onyeka, T. and Asiedu, R., in: Crop Protection, volume 26, number 8, pages 1259-1265, ISSN 0261-2194, 2007.
 
Abstract:
Anthracnose and virus diseases exert devastating impacts on yam production in many tropical regions of the world where the crop contributes to food security and income generation. The complexities in their epidemiology necessitate the use of integrated approaches in their management. Six genotypes of Dioscorea alata, planted on six dates (March?August) in each of 1998 and 1999 in Ibadan, Nigeria, were evaluated to determine the effects of planting date and genotype on severity of the two diseases. The date of planting had a profound influence on anthracnose severity, contributing 72% of the observed variation due to combined effects of planting date, genotype and their interactions. In contrast, the genotype effect was most dominant with respect to virus severity, accounting for 85% of the total observed variation. Planting in August supported least anthracnose development while April and May plantings resulted in the least severity of virus diseases. While selection of planting time could be used to manage anthracnose disease, its application could be influenced by the prevailing weather conditions in a particular location. Two of the genotypes (TDa 291 and TDa 297) had low severity values for both diseases across the different planting dates. Availability of such sources of multiple disease resistance and appropriate choice of planting date would be very useful in integrated management of the two major yam diseases.

Sink competition and desuckering effects on field performance of triploid and tetraploid plantain genotypes, Tenkouano, A., Vuylsteke, D. and Swennen, R.+, in: Journal of Crop Improvement, volume 20, number 1/2, pages 31-51, 2007. [DOI]
 
Abstract:
Reproductive growth in polyarchic Musa spp. varieties occurs by the simultaneous growth of several shoots, resulting in competitive inhibition of fruit development in the individual shoots, particularly under poor soil fertility conditions. Nine plantain genotypes were forced into single-culm growth by continuous sucker removal in the ratoon crop (RC). There were no significant differences among genotypes for days to flowering (DTF) and days to harvest (DTH) in the plant crop (PC), but significant differences occurred in RC for both traits. There was a negative correlation between degree of sucker growth in the PC and DTF or DTH in RC, indicating that early flowering and maturity in the RC occurred as a result of fast sucker development in the PC. Likewise, bunch weight in the RC was positively correlated with sucker growth in the previous crop. However, sucker growth appeared to compete against the development of the bunch in the PC, resulting in a significant reduction in fruit size but not fruit number. Desuckering significantly reduced DTF and DTH in the RC. Bunch weight and fruit size were significantly improved by sucker removal in the RC. Gains were highest for genotypes that normally produce multiple lateral shoots and lowest for those displaying a more hierarchical growth habit. Thus, sucker removal could be recommended as a crop management option for the polyarchic Musa genotypes.

Cassava is one of the most important sources of carbohydrates for over 500 million people in the (sub)tropics. Cassava plays an important role in the food security of many developing nations, especially in sub-Saharan Africa (SSA). Cassava is highly heterozygous, genetically complex, and many varieties either do not flower or produce few seeds thus hampering conventional crop improvement. Several major constraints limit the production and utilization of cassava roots, including two viral diseases, the Cassava Brown Streak Disease (CBSD) and the Cassava Mosaic Disease (CMD), which are specific to SSA. Farmer-preferred landraces are often susceptible to CBSD and/or CMD. Genetic transformation of cassava could complement conventional breeding programs for CBSD and/or CMD resistance. Current protocols for genetic transformation of cassava are limited to model genotypes which are not used by farmers of breeders in SSA. Since transformation protocols are genotype-dependent, suitable procedures for genetic modification of the landraces need to be developed. We have established somatic embryogenesis and organogenesis for three farmer/breeder-preferred varieties, two from East Africa (cv Kibaha and cv Albert) and one from West Africa (TME12) which are susceptible to CBSD. Primary and cyclical somatic embryogenesis was established for the three varieties. Cotyledon tissues from somatic embryos were used as source explants for Agrobacterium-mediated genetic transformation. Using an intron-interrupted {\^a}{\"i}¿½glucuronidase reporter gene construct under control of the Cassava vein mosaic virus promoter, stably transformed cassava tissues and plants were obtained. Molecular evidence for stable expression of the transgenes will be presented.

Soybean maturity and environmental effects in savanna systems; I: dry matter accumulation, Singh, A.*, Carsky, R., Lucas, E. O.* and Dashiell, K., in: Journal of Sustainable Agriculture, volume 20, number 1, pages 75-93, 2002.
 
Abstract:
Growing soybean varieties with high residue yield may help to sustain the soil organic matter (SOM) content when recycled. Replicated field trials were conducted in four Guinea savanna sites in Nigeria to study the dry matter partitioning in six soybean genotypes and evaluate them for biomass production. The varieties were early TGx1485-1D and late TGx1670-1F in Trial 1 and early TGx1485-1D, TGx1805-2E and TGx1681-3F, medium TGx1809-12E and late TGx923-2E and TGx1670-1F in Trial 2. On average, the proportion of total dry matter ac-cumulated in soybean plant parts was 42% in grain, 36% in stover, 12% in leaf litter and 11% in roots and nodules. While maturity class had no significant effect on the grain yield of soybean, significantly higher dry matter accumulation of roots and nodules, leaf litter, and stover was observed in medium and late varieties compared with early varieties (P < 0.05). Thus, medium and late varieties would be better able to sustain the SOM content than early varieties when the residues are recycled. Strongly acid soils in a high rainfall environment limited soybean biomass production and potential to maintain SOM.

The effect of genotype, location and season on cassava starch extraction, Benesi, I.*, Labuschagne, M.*, Herselman, L.*, Mahungu, N. and Saka, J., in: Euphytica, volume 160, pages 59-74, 2008. [DOI]
 
Abstract:
When cassava is harvested too early, it often leads to reduction in yield, while delayed harvest leads to development of woody and fibrous tuberous roots, and reduction in starch content. The optimum harvest time is not known. The objectives of this study were to determine the effect of genotype, location and season on starch extraction in order to find an optimum harvest regime for cassava, and to find the best parameter for monitoring starch levels in cassava tuberous roots. Results showed that genotypic effect was large for starch weight, starch extraction rate on fresh weight basis, and root dry matter content. This suggested that high starch weights could be realised by selection of suitable varieties for starch extraction. It was found that cassava harvesting and starch extractions should be done between October and November since the highest starch extraction rates were achieved during that period, and drying of the extracted starch using the open air method was fast and convenient. The results also suggested that starch levels can efficiently be monitored using starch extraction rate on fresh root weight basis. Starch content on fresh root basis and root dry matter content can also be used to determine the optimum time to harvest cassava for starch extraction but were inferior to starch extraction on fresh root weight basis.
