为了阐明不同水稻品种产量稳定性的差异,以黄华占系谱品种及亲本为材料,连续两年四季对17个产量相关性状进行考查,应用加性主效应和乘积交互作用(AMMI)模型进行稳定性分析.结果表明,在四种环境下水稻产量发生较大变化,变幅为2.21%~19.45%,不同品种间产量的稳定性存在较大差异,其中产量稳定性最好的是丰矮占,最差的是双桂36.各品种的产量相关性状稳定性差异较大,粒宽和剑叶宽稳定性最好,稳定性系数均值分别为0.043和0.049;产量稳定性居中,稳定性系数为0.178;每穗总粒数稳定性最差,稳定性系数为0.935.系谱品种稳定性分析表明,长丝占的引入使得系谱品种产量稳定性大幅提升.随着育种目标的变化,稳定...

In order to illuminate the difference in yield stability for different varieties,yield stability was analyzed with varieties derived from Huanghuazhan and their parents as materials based on 1 7 yield-related traits for four consecutive seasons in two years by using the Additive Main effects and Multiplicative Interactions （AMMI）model.The results showed that rice yield greatly changed in the four environments,ranging from 2.21 % to 1 9.45 %.The yield stability and yield-related traits stability were variety-dependent,with the highest yield st...
