| 摘 要： | 利用厚皮甜瓜单性花材料(雌雄异花同株)作母本,对薄皮甜瓜品种(雄全同株)进行单性花转育,杂交F1代均表现为雌雄异花同株,F2代表现为雌雄异花同株和雄全同株3∶1的分离比例,回交后代出现雌雄异花同株和雄全同株1∶1的分离,以上各世代单性花性状遗传分离规律的结果表明,甜瓜单性花性状受单显性基因控制,遗传简单而稳定。经杂交1代,回交2代的转育,后代果实性状逐渐趋于薄皮甜瓜品种,性状表现优良,通过连续4代自交筛选,获得了单性花性状稳定的薄皮甜瓜单性花系2份,可用于杂交一代制种。

| Abstract: | It was studied to transfer the monoecious character of monoecious muskmelon to oriental melons with andromonoecious character through crossing.F1 hybrids expressed monoecism.The ratio of monoecism and andromonoecism in F2 generations was 3:1.Backcrossing with andromonoecious oriental melons,the generations showed monoecism and andromonoecism separated in the ratio of 1:1.The results showed that the monoecious character was controlled by single dominant gene,which heredity was simple and steady.The crossing ... |
