Abstract

The data was generated from twenty morphological and disease traits for estimating the correlation and path coefficient analysis, stability and diversity analysis. In results of genotypic & phenotypic correlation and path coefficient analysis, the maximum and positive correlation of yield was stand with the fruit average weight of 10 fruits (0.311 & 0.302), number of fruits/plant (0.275 & 0.291), fruit weight (0.253 & 0.241cm), fruit size of scar around peduncle end (0.213 & 0.202) and fruit number of locules (0.264 & 0.252), while, the yield was negatively correlated with some horticultural traits along with ToLCV (-0.582 & -0.557) and early blight (-0.375 & -0.360). Some characters showed low heritability (<1.00) with high genetic advances like Stem length of internode between 1st and 4th inflorescence (0.967 & 18.866), time of 50% flowering (0.997 & 13.799), fruit average weight of 10 fruits (0.999 & 48.535), number of fruits/plant (0.987 & 19.721), time of maturity from seed sowing (0.940 & 15.822), ToLCV (0.985 & 31.765) and early blight (0.992 & 37.786) which were exhibited additive gene action. Out of 24, a total 11, 13, 14 and 12 cultivars showed less than or equal to one (b<1 or b=1) regression coefficient for ToLCV (0.39-0.99), early blight (0.11-0.89), SLI (0.50-1.00) and number of fruits/plant (0.58-1.00), respectively.
