基　　金：The study is approved by the state 863 program in China (the program No.2002AA2070002)and Sichuan province 15 rice breeding key project.

摘　　要：Yihui1577 was bred after over 10 generations by crossing R16 and Yunan purple rice. Many new hybrid rice varieties have been bred with Yihui1577, of which Gangyou1577. Ilyou1577, Nyou1577 and Yixiang1577 were certified by Sichuan Crop Variety Release Committee, Gangyou1577 and Yixiang1577 were certified by National Crop Variety Release Committee. The series varieties bred with Yihui1577 have been used widely with accumulated area of 1,200,000 ha. By using Yihui1577 as breeding material, an excellent restore line Yihui3003 and some other restore lines, such as Yihui1979 and Yihui315 with good quality and combination ability have been bred. Analysis of combination ability and stability of restore line Yihui1577 was made by using agricultural experimentation and statistical approach. The combination ability analysis was made by not complete dual crossing method with 4 CMS lines and 6 restorer lines. It shows that the general combination ability effect value of Yihui1577 is 0.226, while Minghui63 is -0.113. So the general combination ability of Yihui1577 is prior to that of Minghui63. Stability analysis shows that the F value of Gangyou1577 is 1.81378, while Sanyou63 is 1.40327, both doesn＇t reach significant level. So Gangyou1577 has the same stability as Sanyou63.The same conclusion is got in the stability analysis of the breeds of II you 1577, Yixiang1577, Nyou 1577 and so on.以R16与云南紫稻杂交,经多代后,稳定育成宜恢1577,应用宜恢1577已配较多品种,经省级审定的有冈优1577、II优1577、N优1577、宜香1577等,其中冈优1577、宜香1577通过中国国家审定。宜恢1577所配系列组合现已累计推广达120万hm2。将宜恢1577作为材料运用到恢复系的选育,育成突破性恢复系宜恢3003,同时还育成宜恢1979、宜恢315等优质强配合力恢复系。本文运用田间试验设计的方法,比较系统地研究了宜恢1577的配合力和稳定性。用4个不育系与6个恢复系组成4×6不完全双列杂交作配合力分析,结果宜恢1577一般配合力效应值为0.226,明恢63为-0.113,所以宜恢1577的一般配合力优于明恢63;以冈优1577为例对用宜恢1577所配组合进行品种稳定性分析,结果冈优1577稳定性分析的F值为1.81378,未达显著标准,汕优63稳定性分析的F值为1.40327,未达显著标准,二者F值接近,所以冈优1577同汕优63一样存在较好的稳定性,对用宜恢1577所配其他品种的稳定性也进行了分析,结果同汕优63一样没有显著F值,都具有较好的稳定性。
