摘要: 选取黄瓜两个雌雄同株型的强雌性高代自交系材料与普通雌雄同株、两性花株、纯雌株高代自交系材料杂交, 通过对F1、F2、BC1 -1 和BC1 -2 代性型观察, 统计分析表明: 雌雄同株型的强雌性由1对不完全显性和1对隐性基因控制, 暂定名为Mod-F1和mod-F2, 它们是新发现的黄瓜性别表达的两个基因, 能增强黄瓜植株雌性的表达, 与F和M 基因独立遗传。

Abstract: Through the analysis of the sexual character ofmonoecious plants based on the ability of producing exclusively female flowers at later stages, monoecious cucumber could be divided into two groups of monoecious: common monoecious and monoecious-subgynoecious (MOA-subgynoecious). In the experiment, which 5 parental combinations from inbred two MOA-subgynoeciouses (98217, S22298) , monoecious (95) ,gynoecious (W I1983G) and hermaphrodite (W I1983H) and their F2 , BC1 -1 , BC1-2 were as research materials. Genetic analysis showed the MOA-subgynoeciouswith the ability of producing exclusively female flowers at later stagerswere controlled respectively by one pair of incompletely dominant gene and one pair of recessive gene, which were respectively designated presently as Mod-F1 and mod-F2. Genes Mod-F1 and mod2F2, which enhanced the intensity of femaleness, inherited independently with F and M genes.
