Abstract: In order to select new cultivars of bitter gourd, 26 hybrid combinations were made based on the expected F1 traits by using 23 bitter gourd core parents. Through the comparison of the first female node, melon shape, pedicel shape, melon tail shape, melon meat thickness, single melon weight and other traits and yield, the five excellent combinations of MA0361×ZK25-2, ZK90×ZK54, ZK91×ZK90, YW8×ZK54, YW4×ZK25-2 were screened, and the yield were increased by 41.5%~95.6% than that of the control, which were suitable for trial planting. |
