The work is aimed at recombining several desirable traits that included promiscuity, high yield, high biomass, earliness, rust tolerance, drought tolerance and adaptation to the southern Africa conditions. At Chitedze, Malawi, segregating populations of F 2 and F3 generations were grown to select for adaptation, earliness, disease resistance, high biomass and pod load in the 2009/10 season. High shoot biomass is an indicator of enhanced biological nitrogen fixation as the plots did not receive nitrogenous fertilizers. A total of 33 individual plants were selected for these desirable traits from the F 2 crosses. From the F 3 a total of 1099 individual plants were selected. F 1 plants were also raised in the screen house from 18 crosses and their F 2 seeds were harvested. At IITA-Ibadan station, a total of 378 F 3 family rows were raised in 2009 from 33 crosses and a total of 485 individual plants were selected for their rust and other leaf diseases resistance, vigorous biomass and pod load (Table 11-23). Similarly, 130 F 5 family rows were grown at the same location and 183 desirable plants in terms of disease resistance, vigor and pod load were selected (Table 11-24). A total of 21 new crosses were also made from selected parental lines. Recombinant inbred lines (RILs) from two crosses were also raised for phenotyping. From TGx 1485-1D × UG5 and TGx 1485-1D × Soy104, a total of 299 and 287 RILs, respectively, were phenotyped for disease resistance and other associated traits. The F4 and F6 families of the selected plants were also grown in 2010. 236 Engaging Smallholder Farmers | Tropical Legumes II Project
