杂交水稻不育系种子的纯度对杂交优势的发挥影响很大。不育系、保持系的纯度鉴定,一般采用花期鉴定。1987年3月,我们开始采用镜检种子颖壳内柱头鉴定杂交水稻三系及子一代种的真实性的研究。
The purity of the hybrid rice male sterile lines has a great influence on the hybridization advantages. Sterile lines, to maintain the purity of the line, the general use of flowering identification. In March 1987, we began to examine the authenticity of three-line and one-seed hybrids of hybrid rice by microscopic examination of the stigma of the seed husk.
