Genetic variability analysis in brinjal (Solanum melongena L.)

Abstract

The research experiment was conducted to study genetic variability analysis for total 7 characters (5 quantitative and 2 bio-chemical) among 30 genotypes of brinjal (Solanum melongena L.). The investigation was conducted during Rabi season in the year 2021-22 at Rambhas Farm, Hill Millet Research Station, Navsari Agricultural University, Waghai, The Dangs, Gujarat, India. The study revealed high significant difference for most of the traits. Moderate GCV and PCV values were recorded for Average fruit weight (18.93%, 19.63%), Total no. of fruits per plant (18.47%, 19.51%), Total yield (16.62%, 17.80%) and Yield per plant (16.64%, 17.82%). It indicated that the extent of genetic variation observed was somewhat less for these characters among genotypes studied. High heritability coupled with high genetic advance were recorded for Average fruit weight (92.95%, 37.59%), Total no. of fruits per plant (89.67%, 36.04%), Total soluble solids (85.10%, 20.22%), Total yield (87.11%, 31.95%) and Yield per plant (87.15%, 32.00%) indicated that the characters were controlled by additive gene action and selection would be effective.
