摘要 根据多点试验资料,运用高稳系数法.对C815S系列杂交稻组合的高产稳产性进行综合分析和评价。结果表明:C815S所配系列有8个组合的产量显著或极显著高于对照汕优63、C两优1102、C两优87平均产量比汕优63增产9.8%以上,虽然稳产性一般,但这两个组合丰产性好。参试组合对不同试验地点的适应性有显著差异,其中有5个组合的高稳系数高于对照,C两优343、C两优1768的高稳系数都在90以上。 According to the datum of multi-location experiments, the high yield stability of C815S hybrid rice combinations was comprehensively analyzed and evaluated by the method of high stability coefficient. The results showed that the yield of eight hybrid combinations, which derived from the C815S, were significantly higher or extremely higher than that of the control; the average yield of Cliangyou1102 and Cliangyou87 all increased by over 9.8% than that of Shanyou63, although the stability of these two combinations was commonly, but the fertility of them was great; the adaptability of each experimental varieties in different experimental locations was significantly different, the high stability coefficient of five combinations was higher than that of control, and the high stability coefficient of Cliangyou343 and Cliangyou1768 were over 90.
