A study on genetic diversity and genetic variability in brinjal

Twenty three genotypes of brinjal were assessed to know the nature and magnitude of genetic divergence and genetic variability for fruit yield and its contributing characters. The population was grouped into six clusters. The cluster I comprised of six genotypes followed by cluster II and III each with five genotypes, while the cluster VI was solitary cluster. The clustering pattern indicated that there was no association between geographical distribution of genotypes and genetic divergence. However, the shape and colour of fruits of genotypes played major role in grouping of genotypes into various clusters. The maximum inter cluster D2 value was reported between cluster II and III. The GCV, heritability and genetic advance as per cent of mean were high for fruit length, fruit girth and 10-fruits weight indicating additive gene action which contributed maximum divergence and played major role in improvement of brinjal yield.
