dc.description.abstractThe experiment was conducted at farm, Department of Genetics and plant Breeding, College of Agriculture, Raichur during kharif-2016. The experimental materials comprised of twenty eight chilli genotypes along with two susceptible checks. The experimental was laid out in completely randomized design in two replication with the objectives of evaluation of chilli genotypes for fruit borer resistance and quality parameters, to understand the association between quality parameters and fruit yield and to assess the genetic diversity for quality parameters. Analysis of variance showed highly significant difference among the thirty genotypes for most of the characters under study indicated that there is ample scope for selection. Desired traits like plant height, number of fruits, number of seeds and fruit colour showed high heritability coupled with high genetic advance as percent of mean. Correlation analysis revealed that yield was dependent on the yield attributing traits like fruit weight, dry matter, capsaicin content and chlorophyll content indicated that these are important parameters in improvement of chilli. Path analysis revealed that characters like plant height, number of primary branches, number of fruits, fruit diameter, fruit weight, number of seeds, dry matter, fruit pericarp thickness, fruit length, fruit colour, ascorbic acid, phenol content, chlorophyll content, soluble solids and fruit wrinkle showed positive direct effects on yield per plant. Among the 30 genotypes screened for fruit borer resistance, two genotypes namely Raichur Bullet and 07-L showed resistant reaction to fruit borer. Quality parameters like phenol, capsaicin and oleoresin were positively correlated with fruit borer resistance. Genetic divergence studies revealed that the genotypes were grouped into seven clusters based on yield and yield attributing characters and seven clusters based on quality traits suggested that the genotypes differed significantly among themselves when all the characters were considered simultaneously and there is considerable amount of diversity in these genotypes.en_US
