孤雌生殖就是母体的卵细胞不经过受精就发育为成体的生殖方法。由孤雌生殖所产生的后代的遗传性较纯,有较高的育种价值,因此,近年来国内外已开始把诱发孤雌生殖应用于作物育种。 在油菜育种方面,有人用自交系杂交的方法,生产杂交油菜,利用杂种优势,取得了较好的效果。但是,要培育稳定、纯合的自交系,往往需要较长的时间。而运用诱发孤雌生殖的方法,则可在2—3年的较短时间内育成稳定、纯合的自交系,使杂种优势
Parthenogenesis is the reproductive method in which the mother’s egg cells develop into an adult without fertilization. The heritability of parthenogenetic offspring is more pure and has higher breeding value. Therefore, in recent years, parthenogenesis has been applied in crop breeding in China and abroad. In rapeseed breeding, some people use inbred lines of hybrid methods to produce hybrid rape, the use of heterosis, and achieved good results. However, it takes a long time to cultivate stable and homozygous inbred lines. The use of induced parthenogenesis method, you can breed 2-3 years in a stable, homozygous inbred lines, the heterosis
