遵照伟大领袖毛主席关于“有了优良品种,即不增加劳动力、肥料,也可获得较多的收成。”的教导,我们在水稻杂种优势利用的研究工作中,在探讨甲基砷酸锌对水稻杀雄规律的同时,进行了杂交制种的初步尝试。现就有关几个问题,作如下讨论: 一亲本组合的选配通过对30多个水稻品种的杀雄处理和制种试验,我们认为选择好亲本(尤其是母本)是关系到杀雄和杂交制种成败的关键。甲基砷酸锌是非选择性杀雄药物,它对水稻各器官都会产生不同程度的药害。不同水稻品种 According to the guidance of Chairman Mao, the great leader, on “good varieties, that is, no additional labor and fertilizers can be obtained.” In the research work on the utilization of rice heterosis, Rice kill male rules at the same time, the hybrid seed production of the initial attempt. Here are a couple of questions we will discuss on the following topics: Selection of a Parent Portfolio Through the malevolent treatment and seed production test on more than 30 rice cultivars, we think that choosing a good parent (especially the female parent) is related to killing and crossing Seed production success or failure of the key. Methylzinc arsenate is a non-selective killing drug, it will produce different degrees of phytotoxicity to all organs of rice. Different rice varieties
