Abstract

Thirty two brinjal genotypes were evaluated for thirteen quantitative characters and there was significant difference among the genotypes for all the traits studied. Thakkallapalli Local-3 (2509.73 g) was the highest yielder. High PCV and corresponding GCV estimates were recorded for yield per plant, borer infestation percentage, fruits per plant, fruits per cluster, fruit length, seed weight and calyx length indicating the presence of high variability in the germplasm. Moderate PCV and GCV values were registered for plant height, fruit weight, fruit girth, number of primary branches, days to first flowering and days to first harvest. High heritability coupled with high genetic advance as percentage of mean was registered for all the characters studied.
