针对水稻光温敏核不育系高世代提纯繁殖过程中起点温度漂变的问题,利用生产用安农810S、P88S和C815S 3个光温敏核不育系种子,通过建立2个遗传背景完全相同的不育系大群体,实现核心单株筛选与繁殖同步进行,研究一种不育系提纯繁殖的方法。 Aiming at the problem of the starting temperature drifting in the process of purifying and breeding of high temperature light-sensitive genic male sterile line of rice, using three photo thermo-sensitive genic male sterile lines of Annong 810S, P88S and C815S, The same sterile large groups, to achieve the core of single plant screening and breeding simultaneously, to study a sterile line of breeding methods.
