黄瓜雌花朝向遗传规律初探

Studies on the Inheritance of Female flowers Growth Orientation in Cucumber

通过将不同雌花朝向的黄瓜材料杂交,观察F1雌花朝向及商品瓜率。结果发现:黄瓜雌花朝向越向下,其商品瓜率越高;同类型雌花朝向的材料杂交,其后代F1雌花朝向较为稳定;不同类型雌花朝向的材料杂交后,其F1的雌花朝向趋于中亲值。根据试验结果提出了在黄瓜育种过程中选择雌花朝向向下的黄瓜材料作为亲本,有利于提高黄瓜商品率。

Studied the inheritance of female flowers growth oritation and its commodity rate in cucumber. Results showed that the more toward down of the female flowers growth orientation, the more higher of the commodity rate. It was stable in Hybrid F1 by crossing the same type of female flowers growth oritation, but was towards mid-parent by the different type. In the breeding proceeding, to select female flowers towards down as parents could improve the commodity rate.
