IMPACT OF GREEN FRUIT YIELD AND ITS ASSOCIATED TRAITS ON THE PERFORMANCE OF INDIGENOUSLY DEVELOPED CHILLI HYBRIDS (CAPSICUM ANNUUM L.)

Abstract
Impact of indigenously developed chilli hybrids was assessed for the major yield determining traits viz; number of fruits, fruit weight, pericarp weight, seed weight, fruit length, fruit width and fresh fruit yield. Significant differences were observed among the chilli genotypes for all the traits. The indigenous chilli hybrid (HYB-5) contributed maximum green fruit yield of 36.69 t/ha following HYB-1 (36.17 t/ha) which were statistically at par to each other as compared to the commercial hybrid (222-HYB) with 28.42 t/ha and the local varieties viz; Tatapuri (16 t/ha) and Lounghi (4.60 t/ha). The phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all the traits. The traits like number of fruits per plant, fruit length, fruit weight, pericarp weight and fresh fruit yield not only exhibited high PCV and GCV values but also high worth of heritability in broad sense (86% to 99%) and high genetic advance (32.85% to 60.66%) which signified the existence of large variability, with the least involvement of the environmental factors on the expression of these traits which may be utilized through selection for better improvement. Moreover, the genotypic correlations were generally higher than the phenotypic correlations. Fruit length, number of fruits per plants, pericarp weight and fruit weight were positively and significantly correlated to fresh fruit yield both at genotypic and phenotypic level. This in other words indicated the presence of additive gene action for these characters and can respond well to selection after establishing a meaningful correlation with fresh fruit yield. However, a non-significant correlation existed between fresh fruit yield and seed weight.
