Abstract

Analysis of variance revealed significant differences among the 56 germplasm lines for all the 20 characters indicating the presence of adequate variability among the germplasms. Mean values for all the studied characters were differ significantly, for flowering parameters the gynoecious line (ABG-DG-T-5) deviate significantly from other genotypes in a population. Highest number of fruits per vine noticed in ABG-DG-T-1 (27.55 cm) and lowest in ABG-WT-9 (7.02 cm) bitter gourd genotypes. Average fruit weight recorded higher magnitude of variation ranged from 16.79 g (ABG-DG- T-9) to 221.49 g (ABG-DG-T-1). The highest yield per vine observed in ABG-DG-T-1 followed by ABG-WT-1

Conclusion

The characters showing higher additive variance among yard bitter gourd genotypes suggest that the genetic improvement of such traits could be achieved through selection by using the existing genotypes for those traits that exhibits higher variability. ABG-DG-T-5 can be used as gynoecy donor parent in hybridization with high yielding variety for development of high yielding with more number of fruits per vine. The highest yield per vine observed in ABG-DG-T-1 followed by ABG-WT-1. Moreover, this trait is highly influenced by additive gene action and selection could be effective
