无籽西瓜中没有种子,不能产生下一代。要再栽培无籽西瓜,必须繁殖四倍体西瓜和二倍体西瓜,每年以四倍体西瓜为母本、二倍体西瓜为父本杂交,产生三倍体种子,播种三倍体种子,长出三倍体植株结无籽西瓜(图1)。三倍体种子的制种技术如下: Seedless watermelon without seeds, can not produce the next generation. To re-culture seedless watermelon, tetraploid watermelon and diploid watermelon must be multiplied each year tetraploid watermelon as the female parent, diploid watermelon as the male parent to produce triploid seeds, seed triploid, Triploid plant grow seedless watermelon (Figure 1). Seed production techniques of triploid seeds are as follows:
