摘　　要：根据多点试验资料,运用高稳系数法分析C815S系列杂交稻组合产量构成因素的效应和稳定性,研究C815S系列杂交稻组合产量构成因素变异与高产稳产性的关系。结果表明:供试组合之间的有效穗数、每穗粒数、千粒重、结实率差异显著或极显著;参试组合的产量与穗长呈显著正相关,产量高稳系数与有效穗高稳系数呈极显著正相关。In order to study the relationship between high yield stability and yield component factors of C815S hybrid rice combinations, the effect and stability of yield component factors of C815S hybrid rice combinations were analyzed by high-stable coefficient method based on the datum of multi-location experiments. The results indicated that there were significant or extremely differences among the experimental hybrid rice combinations in the effective panicles number, grain number per panicle, the 1 000-grain weight, seed setting rate; there was a significant positive correlation between yield and spike length of the experimental hybrid rice combinations, and there was a extremely significant positive correlation between high-stable coefficient of yield and high-stable coefficient of effective panicles number.
