Assessment of genetic parameters on various quantitative traits in brinjal (Solanum melongena L.)

Abstract

Present investigation was carried out during rabi 2021 with 18 genotypes and three replications in randomized block design at centurion farm, M. S. Swaminathan School of Agriculture, Centurion University of Technology and Management (CUTM), Paralakhemundi, Odisha. Analysis of variance revealed that the mean sum of square due to genotype was highly significant for all the characters under study except for days to 50% flowering. The estimates of mean performance on fruit yield per plant revealed that the genotype, Pusa Purple Long had highest fruit yield per plant (2.12 kg/plant) followed by Sabour Sadabahar (1.52 kg/plant), Green Long (1.17 kg/plant) and Black Beauty (1.15 kg/plant). The magnitude of genotypic coefficient of variation was lower than the corresponding phenotypic coefficient of variation for all the characters under test. The high estimation of heritability united with high estimation of genetic advance was recorded for the characters like fruit yield per plant, fruit weight, plant height and fruit length. High heritability coupled with high genetic advance as per cent of mean was recorded for the traits fruit length, fruit weight, number of fruits per plant, shelf life of fruit and fruit yield per plant.
