dc.description.abstractThe current investigation was conducted at the Vegetable Research Farm of Banda University of Agriculture and Technology, Banda, (UP), India, during the Rabi seasons of 2021-22 and 2022-23 with 34 genotypes of brinjal (Solanum melongena L.) in a Randomized Completely Block Design with three replications. The data were recorded on sixteen qualitative characters, viz. days to 50% flowering, plant height at 50% flowering (cm), number of flowers per cluster, fruit setting percentage, days to first fruit picking, leaf area index (cm2 ), number of primary branches per plant, fruit length (cm), fruit circumference (cm), fruit diameter (cm), specific gravity of fruits (g/cm3 ), total soluble solid (ºBrix), plant height at last picking (cm), number of fruits per plant, average weight of the fruit (g), and fruit yield per plant (kg), and to estimate genetic variability, correlation coefficients, path coefficients, genetic divergence based on important measurable morphological traits, and randomly designed DNA based fifteen SCoT (Start Codon Targeted) molecular markers. The analysis of variance showed highly significant differences among the thirty-four genotypes of brinjal for all the sixteen characters, indicating significant genetic variation among the existing gene pool. Based on mean performance, genotype BUB-18-27 indicated highest fruit yield per plant and plant height at 50% flowering, whereas Kashi Uttam had maximum fruit weight and fruit circumference among 34 genotypes. Other promising genotypes were BUB-18- 15 for number of fruits per plant, Kashi Taru for fruit length, BUB18-2 for fruit diameter, CHBR-2 for leaf area index, BUB-18-10 for number of primary branches, BUB-18-5 for plant height at last picking, Pusa Shyamal & BUB-18-14 for minimum days to 50% flowering, and BUB-18-2 & BUB-18-14 for minimum days to first fruit picking. High magnitude of GCV and PCV, heritability in a broad sense, and genetic advanceas a percentage of mean were observed for number of flowers per cluster, number of fruits perplant, average fruit weight, leaf area index, fruit setting percentage, fruit length, fruit diameter, fruit circumference, fruit yield per plant, and number of primary branches per plant. At the genotypic and phenotypic levels, correlation coefficients on fruit yield per plant had indicated significant and positive correlation with average fruit weight, fruit length, leafarea index, fruit diameter, fruit circumference, fruit setting percentage, and number of fruitsper plant.
