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，稳定性下降，茉莉丝苗的引入又使品种稳定性再次提高.筛选出的优良种质，可用于培育高稳定性产量性状的水稻新品种，促进水稻高产稳产育种.

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 stability in Feng′aizhan and the lowest in Shuanggui 36.Grain width and top leaf width,with stability coefficients of 0.043 and 0.049,showed the highest stability,followed by rice yield(with the stability coefficient of 0.1 78)and spikelet number per panicle(with stability coefficient of 0.935 ).Pedigree analysis showed that: the introduction of Changsizhan improved yield stability significantly.With changing breeding objectives,the stability index decreased until the introduction of Molisimao.The excellent germplasm resources would contribute to new rice variesty breeding with high stability of yield and yield related traits,thus promoting high and stable yielding rice breeding.
