雌性系是指遗传性相对一致,只发生雌花而无雄花(或基部产生少量雄花)的系统,用它作母本与普通的雌雄同株异花的黄瓜种自然杂交,在雌性系植株上,采收的种子是杂种一代,从而省去了人工杂交或人工去雄环节,降低了制种成本,也便于大面积制种。选育雌性系,我国大陆目前主要采用两种方法:一种是选择强雌性单株,利用其产生的少量雄花,进行授粉留种;另一种方法是用赤霉素处理诱导雄花的发生,其授粉留种则采用集团半分法进行株系间的选择、淘汰
Female line refers to the relatively inherited, only the occurrence of female flowers without male flowers (or a small amount of male flowers at the base) system, using it as the female parent and common hermaphrodite cucumber hybrids naturally in female plants, The harvested seeds are a hybrid generation, thus eliminating the need for artificial hybridization or artificial dehumans, reducing the cost of seed production and facilitating large-scale seed production. Breeding female, mainland China currently mainly adopts two methods: one is the selection of strong female plants, the use of a small amount of male flowers generated for pollination and other species; the other method is the use of gibberellic acid treatment to induce the occurrence of male flowers, The pollination of species is the use of semi-sub-group method to select between strains, eliminated
