Comparison on flower, fruit and seed characteristics of tetraploid and diploid watermelons (Citrullus lanatus Thunb. Matsum. and Nakai)

In this study, the characteristics of tetraploid and diploid watermelon’s flowers, fruits, seeds were examined, their differences investigated. As plant material, ST101 ST82; WL92, WL124, WL134, WL216, WL259-B WL235 used. Flower (pollen viability, pollen germination, number anthers per anther flower); fruit (weight, length, diameter, rind thickness TSS) seed (weight 1000 seed, width, thickness, full number, yield, embryo/seed ratio, germination emergence) parameters terms parameters, watermelon has a higher value than watermelon. According to research results, average was found be in watermelons at 74.48% 71.62%. Pollen viability determined highest WL 235 (95.53%). had values, but length decreased (diploid 19.32 cm; 15.33 cm) significantly. Considering values watermelons, significant decrease occurred yield ratio (57.22%, 225.48 6.33 g/fruit, 57.51% respectively diploids; 37.31%, 57.67 4.90 46.42% tetraploid), no difference observed other parameters.
