Combining Ability Analysis for Fruit Yield in Bottle Gourd [Lagenaria siceraria (Mol.) Standl]

Present investigation was carried out during Zaid season 2019-2020 in (Y1) and 2020-2021 (Y2) at the Main Experimental Station (MES), Department of Vegetable Science, Acharya Narendra Deva University Agriculture & Technology, Nagar, Kumarganj, Ayodhya (U.P) with 21 genotypes six parental line their fifteen F1 hybrids bottle gourd by using diallel (excluding reciprocal) mating fashion. Experiment laid RBD include three replication having each experimental unit rows space 3 (m) apart a plant to spacing 0.50 (m). Significant variances over seasons were found for general as well sca all 17 traits studied pooled which suggested that both additive non-additive gene action most important expression traits. Pooled combining ability analysis revealed parents viz., P4, P6 P2 good combiner fruit yield per plant. An attempt identify desirable based on gca effect se performance character studied. Among 15 crosses P3 x P5 have specific combiners total along other contributing characters follow days first staminate flower anthesis, pistillate length average weight.
