Testing the adaptability of newly introduced crop varieties under potential growing agroecologies is an imperative component of a fast-track breeding approach in Ethiopia. A field experiment was conducted to evaluate the performance of climbing bean varieties for grain yield and other agronomic traits at four locations (Jimma, Haru, Assosa and Pawe...

Climbing bean (Phaseolus vulgaris L.) is an important pulse crop to ensure food and nutritional security in Ethiopia. However, its productivity is below its potential due to use of low yielding local varieties, biotic and abiotic stresses in different growing environments. Limited research was done on climbing bean and a few varieties were develope...

Common beans are important sources of food and cash in Ethiopia. Access to seed of improved bean varieties is the major bottleneck to common bean production. Most of the bean producers obtain seed of improved varieties from few seed suppliers, who are unable to sufficiently produce and sell seed at reasonable price. To improve the accessibility and...

Common bacterial blight (CBB) caused by Xanthomonas axonopodis pv. phaseoli and X. axonopodis pv. phaseoli var. fuscans is one of the major biotic constraints limiting common bean (Phaseolus vulgaris L.) production and productivity in Ethiopia. The objective of this study was to identify new sources of CBB resistance from a diverse panel of genotyp...

Common bean research program of Ethiopia aimed at development of demanded variety for enhanced adoption, improve food and nutrition security as well as to boost income of smallholder farmers thereby enhancing foreign earnings of the country. To achieve these aim, the breeding program use different strategies. These incudes, importing demanded varie...

Common bean (Phaseolus vulgaris L.) is an important staple crop for smallholder farmers, particularly in Eastern and Southern Africa. To support common bean breeding and seed dissemination, a high throughput SNP genotyping platform with 1500 established SNP assays has been developed at a genotyping service provider which allows breeders without the...

Common bean (Phaseolus vulgaris L.) contributes to food and nutrition security, and income generation for smallholder farmers and enhances foreign exchange earnings in Ethiopia. The crop is one of the major pulses that serve as a rotational crop in cereal based cropping systems in the lowland areas. However, the gap between the potential and nation...

The common bean research program in Ethiopia aims at contributing to the improvement of the livelihoods of smallholder farmers through generation and promotion of improved demand driven and climate-smart common bean based technologies and information thereby enhancing foreign currency earnings of the country. To achieve these goals, the breeding pr...

In Ethiopia, common bean breeding has been done through introduction of advanced germplasm form the CIAT and local cross making and evaluating the genotypes across years and locations. Through PABRA, bean varieties with known market attributes have also been imported and went through fast tracked evaluation and best ones released. In situ populatio...

Common bean variety selection within its production environment is often challenged by the occurrence of significant genotype-by-environment interactions (GEI) in the variety development process. Grain yield performance of 16 navy bean (Phaseolus vulgaris L.) lines was tested in a multi-environment variety trial during 2010 and 2011 main growing se...

Due to limited commercialization of legume varieties by the private sector, the legume seed system has remained rather underdeveloped and weak in many countries of sub-Saharan Africa. The TL II project developed and successfully implemented innovative seed delivery models that significantly impacted the seed systems in 13 countries of SSA and two i...

When genotypes are introduced into a new and diverse production environments, occurrence of significant genotype by environment interaction (GEI) complicates selection of stable genotypes. Therefore, fifteen introduced and one check small red common bean lines were evaluated at five representative dry bean growing locations of Ethiopia for seed yie...
