Abstract

Eighty one brinjal genotypes (nine parents and 72 hybrids) were evaluated for 14 characters. Results showed that marketable
yield per plant had significant positive association for both at genotypic and phenotypic level with all the characters studied viz.,
plant height, number of branches per plant, fruit girth, calyx length, number of fruits per plant, single fruit weight, protein content
and total phenol content. The earliness showed positive association with fruit borer infestation both at genotypic and phenotypic
level. The marketable yield per plant had significant negative association both at genotypic and phenotypic level with shoot and
fruit borer infestation. Neither positive nor negative significant correlation was registered by shoot borer infestation with other
characters. The shoot borer infestation showed negative relation with ascorbic acid content, protein content of fruit and total
phenol content at vegetable maturity.
