种子质量由种子纯度、净度、发芽率、水分等要素构成,其中最关键的是种子纯度,也是生产上最敏感的问题。为了搞好蜀杂6号的纯度检验,我们从分析它的生产过程着手,确定了与种子纯度非常密切的三个技术环节及造成的后果:一是制种过程中,必须在核不育两用系始花前将占总株数50%左右的可育株彻底士净砍除并运出生产田块,否则可育株与不育株授粉后将在下一代分离出50%左右的不育株。
Seed quality by the seed purity, clarity, germination rate, moisture and other elements, of which the most critical is the seed purity, but also the most sensitive production issues. In order to improve the purity of Shu hybrid No. 6, we start from the analysis of its production process, to determine the very close and the purity of the seeds of the three technical aspects and the consequences: First, the seed production process must be two nuclear infertility With the beginning of the line before the total number of plants will be about 50% of the total fertility plants net cut off and shipped out of production plots, or fertile plants and sterile plants pollination in the next generation will be isolated about 50% of infertility Strain.
