The experimental material comprised of 33 genotypes including ‘Surajmukhi’ as standard check was evaluated in randomized complete block design with three replications during summer-rainy season 2017. The estimates of PCV and GCV were high for dry fruit yield/plant and it also showed high heritability coupled with high genetic advance along with marketable red ripe fruit yield/plant, non- marketable red ripe fruits/plant, dry fruit yield/plant and oleoresin content. Majority of the traits showed high heritability along with moderate estimates of PCV, GCV and genetic advance. Correlation studies revealed that marketable red ripe fruit yield/plant showed positive association with fruit length, fruit girth, fruit width, plant height, average red ripe fruit weight, marketable red ripe fruits/plant, total red ripe fruits/plant, per cent marketable red ripe fruits/plant, average dry fruit weight and dry fruit yield/plant at both the levels. Total red ripe fruits/plant directly contributed maximum toward the marketable red ripe fruit yield/plant followed by per cent marketable red ripe fruits/plant contributed directly to a limited extent at both phenotypic and genotypic levels. Thus, indicating direct selection for these traits as a criterion for yield improvement in chilli. | Studies on variability, correlation and path analysis in red ripe chilli genotypes
