Design-II analysis for estimatimg general and specific combining ability effects of cotton leaf curl virus resistant inbred parents [electronic resource].

Includes references.

Combining ability estimates are very important attributes to cotton breeders in predicting genetic improvement that could be made through hybridization and selection. Cross Classification Design-II analysis that involved 5 cotton leaf curl virus (clcv) susceptible male and 5 clcv resistant female inbred parents were crossed in cotton research institute, Sindh, Pakistan, during summer Season 2000 and 2001, thus forming 25 intrahinutum F1 hybrids were studied. The mean squares due to male and female parents both determined general combining ability (GCA) variances and males x females which pertained to specific combining ability (SCA) variances were significant for all the six characters.
