Studies on genetic variability, heritability and genetic advance in Brinjal (Solanum melongena L.)

Abstract

The current study was conducted in a Randomized Block Design with three replications at the Crop Research Center-1, School of Agriculture, ITM University Gwalior (Madhya Pradesh), during the Rabi season of 2022–2023. Fourteen quantitative characters from 18 brinjal genotypes were assessed, and it was discovered that there were substantial differences in all the features examined. All of the genotypes and characters under examination showed highly significant differences, showing that each character had a considerable level of variability. For every character analyzed, PCV estimates were greater than their matching GCV. Fruit width (41.29% and 41.2%), average fruit weight (36.44% and 35.89%), fruit production per plant (32.15% and 31.88%), flower count per cluster (31.17% and 27.93%), and days to first flowering (25.24% and 24.65%) all had high PCV and GCV values. Fruit width (83.94 and.), average fruit weight (72.80%), fruit output per plant (65.11%), number of flowers in cluster (51.57%), and days to first blossom (49.58%) were all found to have high heritability along with high genetic progress.
