Twelve genotypes of brinjal including check “Pusa Purple Long” were evaluated in Randomized Complete Block Design to assess the extent of genetic variability, heritability, genetic advance, character association and path coefficient analysis with respect to various horticultural traits including marketable fruit yield per plant. Analysis of variance indicated significant difference among the various genotypes with respect to all the traits studied. Best genotypes in terms of marketable fruit yield per plant was B-COHF-NERI-41(1.23 kg), B-COHF-NERI-50 (1.17 kg) and B-COHF-NERI-43 (1.00 kg). The traits viz. ascorbic acid, fruit length, average fruit weight, weight of 100 seeds, fruit diameter, marketable fruit yield per plant and number of primary branches expressed high GCV and PCV values. High heritability was exhibited by the trait ascorbic acid followed by number of seeds per fruit, weight of 100 seeds, total soluble solids, days to first harvest, plant spread, fruit length, number of primary branches, average fruit weight, pedicel length, plant height, harvest duration, leaf length, stem diameter and days to 50% flowering. However, high genetic advance as percentage of mean was observed for the trait ascorbic acid followed by the traits fruit length, average fruit weight, weight of 100 seeds, harvest duration, fruit diameter, number of primary branches, marketable fruit yield per plant, leaf length, pedicel length, plant height and total soluble solid. The trait marketable fruit yield per plant had positive and significant character association with the traits viz. pedicel length, average fruit weight, fruit diameter, number of seeds per fruit, weight of 100 seed, number of primary branches, stem diameter, plant height, plant spread and ascorbic acid both at genotypic and phenotypic levels respectively. Path analysis studies showed that highest positive desirable direct effect on marketable fruit yield per plant was observed by the character average fruit weight.EnglishThesis
