Abstract

Genotypic correlation coefficients and path coefficients among fruit yield and other elevan yield related traits in brinjal were estimated from 15 diverse genotypes evaluated during two consecutive years. Fruit yield was significantly and positively correlated with fruit number and ratio of length of peripheral seed ring. It had negative correlation with fruit diameter and mesocarp thickness. Mesocarp thickness also showed positive association with infested shoot percentage, fruit diametere and ratio of length of seedless area while it was negatively associated with fruit number, fruit length and ratio of length of peripheral seedling area. Percentage of infested fruit yield was highly positively correlated with infested fruit number percentage. Path analysis indicated that mesocarp thickness had the maximum influence on fruit yield followed by fruit diameter, fruit number and ratio of length of peripheral seedring, suggesting that the improvement in fruit yield could be efficient if the selection is based on these component characters.
