Association of charecters on yield and shoot and fruit borer resistance in brinjal (Solanum melongena L.)

Eighty one brinjal genotypes (nine parents and 72 hybrids) were evaluated for 14 characters. Results showed that marketableyield 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,...

Description
Summary:Eighty one brinjal genotypes (nine parents and 72 hybrids) were evaluated for 14 characters. Results showed that marketableyield 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 contentand total phenol content. The earliness showed positive association with fruit borer infestation both at genotypic and phenotypiclevel. The marketable yield per plant had significant negative association both at genotypic and phenotypic level with shoot andfruit borer infestation. Neither positive nor negative significant correlation was registered by shoot borer infestation with othercharacters. The shoot borer infestation showed negative relation with ascorbic acid content, protein content of fruit and totalphenol content at vegetable maturity.
