Combining ability over environments for shoot and fruit borer resistance and other quantitative traits in Solanum melongena L.

Abstract

Ten parents and their 45 F1's were evaluated for fruit yield and its component characters along with shoot and fruit borer infestation over four environments. Highly significant variation was observed due to genotypes and environments for all the twelve characters studied. Both gca and sca variances showed significant interactions. The genotypes ABV 1, PBR 129-5 and Aruna were found to be good general combiners and 15 crosses have been identified as good specific combiner for fruit yield and other related traits. The genotyps PBR 129-5 had shown highly significant negative gca effects for shoot and fruit borer infestation.
