  • 92-9146-058-3
Subject(s): Summary: From 11,000 bread wheat introductions screened in Kenya between 1984 to 1986, six genotypes were selected with stable resistance to leaf, stem and yellow rust and with good agronomic performance. These selections were crossed with three Kenyan commercial cultivars in a half diallel. Selection for near complete or complete resistance to yellow rust and good agronomic performance was performed at each generation of advancement. Twenty-one F7 genotypes, representing 1O crosses were ultimately selected. These were entered into preliminary yield trials in 1992 and 1993. Seven entries were advanced to the National Performance Trial in 1994, 1995 and 1996. Three genotypes K.7635, K.7638, and K.7642 are now being considered for release.
