Since the first tetraploid was obtained in 1939 , polyploidy breeding has always been the focus of watermelon breeding 从1939年获得第一个四倍体西瓜以来，多倍体育种就一直是西瓜育种的一个热点。
Allopolyploidy a type of polyploidy involving the combination of chromosomes from two or more different species 异源多倍体：两种或两个以上的不相同的物种杂交，杂种经染色体加倍形成的多倍体类型。
Alternatively , like allopolyploids , they may arise by the nondisjunction of chromatids during the mitotic division of a zygote 与异源多倍体相似的是，它们也是在有丝分裂中合子的染色单体不分离形成的。
Autopoly - ploids may arise from the fusion of diploid gametes that have resulted from the nondisjunction of chromosomes at meiosis 同源多倍体通常可能来自在减数分裂过程中染色体不分离导致的二倍体融合。
