Abstract: Understanding the direction and magnitude of the correlation between fruit yield and its attributing traits in bell pepper (Capsicum annuum L. var. grossum Sendt.) is a prerequisite for the identification of such characters whose selection would prove beneficial in any breeding programme. The correlation coefficient analysis measures the mutual relationship between various characters and it determines the component traits on which selection can be relied upon the effect of improvement. The correlation coefficient analysis was studied in 43 genotypes in bell pepper for different characters viz., days to 50 per cent flowering, days to first picking, plant height (cm), primary branches per plant, harvest duration (days), fruit length (cm), fruit width (cm), pericarp thickness (mm), lobes per fruit, average fruit weight (g), marketable fruits per plant, marketable fruit yield per plant (g), capsanthin content (ASTA units), TSS (oBrix) and ascorbic acid content (mg/100g) under Randomized Complete Block Design with three replications during summer-rainy season, 2018. Significant and positive correlation of marketable fruit yield per plant, both at genotypic and phenotypic levels was recorded with marketable fruits per plant, harvest duration, average fruit weight and fruit width while significant and negative correlations were observed with days to 50 per cent flowering and days to first picking. The data pertaining to phenotypic and genotypic path revealed that marketable fruits per plant had maximum positive direct effect on marketable fruit yield per plant followed by average fruit weight. Similarly, marketable fruit yield was also increased by positive indirect effects of harvest duration and fruit width. Thus, direct selection for the above traits will be helpful in improving marketable fruit yield of bell pepper.
