dc.description.abstractThe investigation on “Variability and genetic diversity studies in brinjal (Solanum melongena L.) genotypes” was undertaken during Rabi season of 2013. Sixty brinjal genotypes were evaluated in randomized block design with three replications in Sector no.1 under the University of Horticultural Sciences, Bagalkot. Analysis of variance revealed highly significant differences among genotypes for 26 out of 29 characters studied. Broad genetic base was evident as the values of genotypic and phenotypic coefficient of variations were high for number of primary branches (90 and 120 DAT), stem girth at 60 DAT, leaf area (60 and 90 DAT), number of fruits per cluster, number of fruits per plant, average fruit weight, fruit length-diameter ratio, total yield per plant and phenol content. High heritability coupled with high genetic advance over mean was observed for plant height (60, 90 and 120 DAT), plant spread at 60 DAT, number of primary branches (90 and 120 DAT), stem girth at 60 DAT, leaf area (60 and 90 DAT), days to first flowering, number of fruits per cluster, fruit length, fruit diameter, fruit length-diameter ratio, average fruit weight, phenol content, early yield per plant, total yield per plant and per cent dry matter in fruits indicates predominance additive gene action. Thus, there is ample scope for improving these characters through direct selection. Correlation studie s revealed significant and positive association of total yield per plant with fruit diameter, early yield per plant and number of fruits per plant. Path analysis studies revealed high direct effects of number of fruits per cluster and early yield per plant on total yield per plant. Mahalanobis D2 analysis grouped 60 genotypes of brinjal into seven clusters. The cluster III showed maximum intra-cluster distance and maximum inter-cluster distance was observed between clusters III and VII. Average fruit weight contributed maximum (52.32%) to the genetic diversity followed by number of fruits per cluster (14.52%) and plant spread at 60 DAT (13.90%). Heterosis studies can be planned by involving genotypes belonging to cluster III and cluster VII. The high yielding genotypes having purple coloured fruits with white stripes and spiny (CBB-6, CBB-17, CBB-29 and CBB-45), green coloured fruits with white patches and spiny (CBB-7 and CBB-23) and purple coloured fruits with green stripes (CBB-1) can be further assessed for stability before exploiting them for commercial cultivation.en_US
