The present experiment was formulated on vegetable research farm, Bihar Agricultural University, Sabour to study the per se performance of 21 hybrids with seven dissimilar parents. The ANOVA for experimental design expressed that the treatment variance were highly significant for all the quantitative and qualitative traits. Fruit yield is the ultimate character which shows the utility of a genotype in farmer’s field. As per the present findings, the parents Pusa Ausadhi, followed by BRBT Local and Kathi were the most promising parental line. However, among hybrids, Pusa Ausadhi X BRBT Local followed by Kathi X BRBT Local and BRBT Local X Konkan Tara were considered as best hybrid regarding fruit yield. For quality point of view, the best promising parent were found to be BRBT Local for total soluble solid (TSS) and chlorophyll content, Konkan Tara for carotenoid content, Kathi No. 1 for total phenol content and Konkan Tara for ascorbic acid. Out of 21 hybrids, BRBT Local X Konkan Tara had highest ascorbic acid content followed by Kathi X Konkan | Study of per se performance of parents and hybrids for yield and quality of bittergourd (Momordica charantia L.)
