ABSTRACT
Forty three genotypes include 6 lines, 5 testers, 30 F1 hybrids and two checks (Tejaswini and Indam-5) were evaluated in three different environments for stability analysis. Variance due to genotypes × environment interactions were significant for all the characters. Considering all the yield attributing traits and yield together, it was found that three genotypes were most stable for fruit yield per plant with high mean yield performance. The hybrid LCA 704 x LCA 315 had the highest mean value for fruit yield and fruit length, number of fruits per plant, average fruit weight and seed weight. The second high yielding genotype LCA 704 x LCA 703 was found to be highly stable for per cent fruit set, number fruits per plant, fruit length, average fruit weight, seed weight and vitamin C content. The third high yielding genotype LCA 712 x LCA 703 was stable with respect to plant height, plant spread, per cent fruit set, fruit length, average dry fruit weight and the seed weight. It can be concluded that three hybrids viz., LCA 704 x LCA 315, LCA 764 x LCA 315 and LCA 712 x LCA 703 are stable with desirable per se performance for fruit yield and other important traits. These hybrids may be further tested over locations and years, and recommended for commercial release. The knowledge and material generated in the investigation could be utilized for future chilli breeding programmes.
