运用 AMMI模型对 1 996年全国籼型杂交稻区域试验中稻两系组资料进行分析 ,结果表明 :组合稳定性评价很重要 ,基因型与环境的互作达极显著水平 ,互作效应 (平方和 )几乎为基因型效应 (平方和 )的 2倍 ,AMMI模型的前三个主成分共解释了 80 .4 1 %的交互作用信息 ,为线性回归模型的 3 .1倍。安湘 S/ 871 3、两优 T63表现出较高产且稳产 ,培矮 64 S/山青 1 1、培矮 64 S/ 2 4 1 0、培矮 63 S/ R3 1 8表现较稳产而不高产 ,两优 79、培矮 64 S/ JR1 0 68既不高产也不稳产。
The AMMI model was used to analyze the data of two lines in the regional experiment of indica hybrid rice in China in 1996. The results showed that the combination stability was very important, the interaction between genotype and environment reached extremely significant level, and the interaction effect ) Was nearly double the genotype effect (sum of squares). The first three principal components of the AMMI model explained a total of 80.41% of the interaction information, which was 3.1 times of the linear regression model. Anxiang S / 871 3, Liangyou T63 showed higher yield and stable yield, Pei’ai 64 S / Shanqing 1 1, Pei’ai 64 S / 2 4 1 0, Peiwa 63 S / R3 1 8 showed stable yield High yield, Liangyou 79, Peiwa 64 S / JR1 0 68 neither high yield nor stable yield.
