Stability Analysis for Growth and Yield Attributes in Brinjal (Solanum melongena L.)

The present investigation was carried out to study stability performance over three locations for fruit yield and its components in 51 genotypes (36 hybrids + 15 parents) of brinjal using Line x Tester mating design. The analysis further revealed that component of G x E interactions were significant for plant height, days to 50 per cent flowering, average fruit weight, number of fruits per plant, fruit yield per plant and ascorbic acid indicating that linear as well as own linear component were important. In present experiment, none of the parent showed average stability for fruit yield per plant and its component characters while only one cross, JBL-08-08 x NSR-1 exhibited average stability for fruit yield per plant. Parents as a group yielding slightly higher mean value as compared to hybrids.
