Abstract:

The present experiment was conducted to study correlation and path analysis for yield and quality traits of 28 genotypes. Significant variations were found among the genotypes for characters studied. The correlation coefficient analysis at genotypic level revealed that fruit yield per vine had positive and significant association with fruit number per vine (0.85), fruit weight (0.613), fruit equatorial diameter (0.53), ascorbic acid content (0.69) and crude fibre content (0.49). Path coefficient analysis at genotypic level revealed that number of fruits per vine exerted the highest positive direct effect (3.64) on total yield per plant followed by sex ratio (2.29), fruit polar diameter (1.83), days to first harvest (1.57) and fruit equatorial diameter (0.92). Besides this negative direct effect on yield per plant was recorded by 100 seed weight (-2.06), ascorbic acid content (-1.12), fruit weight (-1.03), β-carotene (-0.90) and days to first female flower appearance (-0.39).
