Estimation of combining ability in bottle gourd [Lagenaria siceraria (Mol.) Standl.]

This study was conducted to estimate combing ability in bottle gourd. Fifty eight gourd genotypes comprising 45 hybrids, 10 parents and 3 checks were evaluated three different environments. The data analyzed as per Method-II, Model-I of Griffing (1956). Significant GCA effects desirable direction evident the inbred lines P6, P2 SCA hybrids P9 x P10, P4 P6 for days first harvest on pooled basis number branches vine. with significantly positive vine P5, P3 P8, harvest.
