Abstract


Different crosses of groundnut were evaluated in generating productive, late leaf spot resistant segregants with desirable agronomic features. A large amount of variability was observed for pod yield and resistance when the single and multiple crosses were advanced from s1 to s3 generation by different selection schemes. Back cross and three way crosses were marginally superior over other crosses in mean performance and frequency of desirable segregants for all the yield parameters. On the other hand, single and double crosses were more resistant to late leaf spot. Higher proportion of desirable recombinants in three way and back crosses revealed the possibility of breaking the undesirable linkages in these cross categories. Single and double crosses were poor in giving superior recombinants indicating the need for selective intermating between desirable groups
