利用黄瓜雌性系做母本用于杂种一代制种,可节省去雄用工,提高种子产量与纯度,是加速黄瓜杂种一代利用的良好途径与措施。为了选育优良的黄瓜雌性系,并用于配制一代杂种,我所于1976年起,开展了黄瓜雌性系选育和利用研究工作,兹将结果初报如下: 一、试验材料及方法 主要应用回交 It is a good way and means to accelerate the utilization of cucumber hybrids by using the cucumber female parent as the female parent for the hybrid generation, which can save male labor and increase seed yield and purity. In order to breed excellent cucumber female lines, and for the preparation of the first generation hybrids, I started in 1976 cucumber female breeding and utilization of research work, the results are as follows: First, the test materials and methods are mainly used back cross
