Okii, DennisBadji, ArfangOdong, ThomasTalwana, HerbertTukamuhabwa, PhinehasMagdalena, WilliamGepts, PaulMukankusi, Clare Mugisha[Responses to selection for yield traits and key diseases among common bean genetic pyramids across locations]Responses to selection for yield traits and key diseases among common bean genetic pyramids across locations

The amount of genotypic and phenotypic variability that exists in a species is important for selection and initiating breeding programs. Yam bean is grown locally in tropical countries of the Americas and Asia for their tasty storage roots, which usually have low dry matter content. The crop was ...

The yam bean (Pachyrizhus spp) was recently introduced as a root crop with high-yield potential, considerable protein and micro-nutrient concentration to investigate its potential for food production in Rwanda. Except for Chuin types (Pachyrizhus tuberosus) which have high storage root dry matter...

Germplasm of common beans from the Mesoamerican gene pool races: Durango, Jalisco, Mesoamerica and Guatemala have highest genetic variation for the crop's improvement. The objective was to assign 50 common bean germplasm in Uganda into its gene pool races based on analyses of population structure...

Kiryowa, M.Nkalubo, Stanley T.Mukankusi, Clare MugishaTalwana, HGibson, P.J.Tukamuhabwa, Phinehas[Effect of marker aided pyramiding of anthracnose and Pythium root rot resistance genes on plant agronomic characters among advanced common bean genotypes]Effect of marker aided pyramiding of anthracnose and Pythium root rot resistance genes on plant agronomic characters among advanced common bean genotypes

Multiple co-infections by different pathogens on common bean (Phaseolus vulgaris L.) affect its productivity and cause complete crop loss in susceptible varieties. Therefore, gene pyramiding using marker assisted selection (MAS) and backcrossing, provide alternative cost-effective control measu...

Root and tubers crops are key staple crops for both rural and urban populations in Rwanda and supporting more than nine million people living in densely populated areas and sustained on agriculture with diverse range of cultivated species. Yam bean (Pachyrizhus spp) was introduced for both its im...

Cassava brown streak disease (CBSD) is the most devastating disease of cassava in southern, eastern and cntral Africa, and can cause up to 100% yield loss. Limited progress has been made in breeding for host plant resistance due to limited knowledge on the resistance variability to the disease....
