Study 2: Highest yielding genotypes in the 10th IWWYT-SA under low and high productive environments, 2008
Conclusions Grain yield of highest yielding genotypes in IWWYT-
IR and IWWYT-SA are comparable under irrigated management
Certain genotypes developed for dryland also possess yield potential that could efficiently utilize management practices for irrigated management
In general, different sets of genetic materials are needed under strictly semi-arid and irrigated environments
A few lines targeted towards stressed conditions in fact possess yield plasticity resulting in their superior performance both under dryland and irrigated conditions
