肉眼如何识别真假杂交水稻种子?我们提出如下几个简易方法: 一、杂交稻种子是不育系通过恢复系授粉后结成的种子,不育系雌蕊柱头大多外露,张颖角度较大,开颖时间较长利于授粉。因此杂交稻种子的谷粒结实后,在内外颖之间。可以见到明显的小黑点,即柱头的痕迹(借用放大镜更好),内 How can we identify the true and false hybrid rice seeds? We propose the following simple methods: First, the hybrid rice seeds are sterile lines formed by the restorer pollination of the seeds, stigma sterility mostly stigma exposed Zhang Ying angle larger, Open time longer conducive to pollination. Therefore, after the grain of hybrid rice seed strong, both inside and outside Ying. Can see the obvious black spots, that stigma marks (borrow the magnifying glass better), inside
