Abstract

The present experiment was carried out to find out the variability among the thirty five diverse genotypes including one check for quantitative traits and qualitative traits. The research was conducted at Main Experiment Station of Department of Vegetable Science, Acharya Narendra Deva University of Agriculture & Technology, (Narendra Nagar), Kumarganj, Ayodhya, U.P. The experiment was conducted in Randomized Block Design with three replications. The wide range of variability among the traits during 2021 (kharif season). Genotypes involved in this study were genetically diverse and have good breeding value, which confirmed the predictions of analysis of variance. Out of 35 genotypes among four genotypes were produced significantly higher yield than best check Narendra Agrim.

Conclusion

Four genotypes viz., NDPK-40, 2018/PUMAR-2, 2018/PUMAR-6 and NDPK-33 were found significantly superior for fruit yield per plant than check variety Narendra Agrim. High magnitude of phenotypic as well as genotypic coefficients of variation were observed for the character average fruit weight 49.674 per cent followed by total fruit yield (kg) 44.835. Heritability and genetic advance revealed that high heritability coupled with high genetic advance was recorded for all the characters except days to first fruit harvest, days to first staminate flower anthesis, days to first pistillate flower anthesis and fruit equatorial circumference. Thus, these traits exhibiting high heritability in broad sense and high expected genetic advance as per cent of mean may be considered to be largely governed by additive gene action and therefore, could be effectively improved through selection.
