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