摘要
本实验结果表明Ⅱ优501制种田适宜的行比为2：10，适宜密度母本为13．3×16.7cm，父本为25.0×13．3cm．每公顷3000kg的群体产量结构，为有效穗2．7～3．0×106／hm2，穗粒数为100－120粒，异交结实本为40％左右，千位党25g左右。
The suitable row ratio of restorer to male-sterila line was 2: 10,the desirable density ofplants was 13. 3×16. 7cm2 for mater parents and 25. 0×13. 3cm2 for patermal parents. The yieldcostruction of 3000kg per hectare were the effective panicles of 2. 7- 3. 0 ×106 per hectare, thespiketets of 100-120 grains per panicle,the cross fericity of 40% and the 25g weight of 1×103grains.
