无子西瓜是利用遗传上三倍体不孕性的特性进行栽培的。无子西瓜植株抗逆性强,生长旺盛,果实产量高(为同品种普通西瓜的1.3～1.5倍),含糖量高(比同品种普通西瓜含可溶性固体物高1度),品质优良(果肉密度较好),供应期长,瓤内无籽,食用方便,深受广大群众欢迎。无子西瓜以四倍体西瓜为母本,普通西瓜为父本,授粉后得三倍体西瓜种子而进行栽培。普通西瓜为二倍体,其体细胞的染色体数2X=22,配子(性细胞)的染色体数X=11。四倍体西瓜是通过人工诱变,使普通西瓜的染色体数加倍而获得。
Seedless watermelon is the use of genetic characteristics of triploid inoculum cultivation. Seedless watermelon plants with strong resistance, strong growth, high fruit yield (for the same species of common watermelon 1.3 to 1.5 times), high sugar content (than the same species of ordinary watermelon containing soluble solids 1 degree), good quality Flesh density is better), the supply period is long, no seeds within the bladder, easy to eat, welcomed by the general public. Seedless watermelon tetraploid watermelon as the female parent, common watermelon as the male parent, after pollination triploid watermelon seeds were cultivated. Common watermelon diploid, the somatic chromosome number 2X = 22, gametes (sex cells) chromosome number X = 11. Tetraploid watermelon is obtained through artificial mutagenesis, doubling the chromosome number of common watermelon.
