dc.description.abstractABSTRACT The present investigation entitled “Genetic variability and characters association in brinjal (Solanum melongena L.) genotypes” was carried out at the Experimental Farm, Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, (HP) during summer-rainy season of 2017, to evaluate fifty diverse genotypes of brinjal in RCBD model replicated thrice. The observations were recorded on plant height, number of branches per plant, days to 50 per cent flowering, days to first harvest, total harvest duration, fruit length and breadth, fruit weight, number of marketable fruits per plant, marketable fruit yield, TSS, ascorbic acid content, incidence of fruit rot, fruit borer and morphological traits viz. growth habit, fruit bearing habit, fruit shape, fruit colour, leaf colour, stem colour, calyx colour and spinyness. Analysis of variance showed highly significant variations among the genotypes for all the qualitative and quantitative traits under study. Long fruited Punjab Barsati (309.17) and UHF BRL - 4 (307.21), oblong fruited PBH - 3 (359.02) and round fruited PBHR - 42 (346.69), SR- 312 (328.85), SR-333 (309.83), SR-305 (275.60), SR-303 (266.87), SR-321(245.95) and UHF BRL-6 (224.83) recorded significantly greater yields (q/ha) over their respective shape’s check varieties i.e. PPL (270.35), Pusa Kranti (245.10) and Punjab Nagina (188.82). High heritability coupled with high genetic gain was observed for incidence of fruit rot and fruit borer, number of fruits/plant, yield, fruit weight, ascorbic acid content, fruit size (length & breadth) and number of branches. High heritability along with moderate genetic gain was observed for plant height, TSS and days to 50 per cent flowering whereas, high heritability with low genetic gain was reported for the traits; days to first harvest and total harvest duration. Yield per plant was positively correlated with fruits/plant, fruit weight and fruit size, total harvest duration and ascorbic acid content. High positive direct effects towards fruit yield/plant were contributed by number of fruit/plant and fruit length at genotypic level. Genetic divergence studies revealed that cluster II, V and VIII accommodated maximum number of genotypes (9). The maximum inter cluster distance was recorded between cluster VII and VIII and therefore, the hybridization between the genotypes of these two clusters will be more rewarding for getting superior hybrids or recombinants in segregating populationsen_US
