利用多年水稻（早籼稻和晚粳稻）区域试验产量结果和有关试验点气候资料，分析 了基因型×环境互作效应结构变化趋势、与主要气候因子以及试点平均产量的关系等．研究表 明，水稻基因型×环境互作效应值在年度间相对稳定，存在着一个相对稳定的数值．单一试点 水平上产生的交互效应值年度间也保持相对稳定．试点的互作效应由固定部分（由土壤等因素引 起）和随机部分（由不确定气候等因素引起）两部分混合组成，两部分约各占５０％．试点互作效应 与试点对品种判别能力的估算参数（Ｄｊ参数）之间均存在着较好的线性相关关系，与试点平均产 量之间则表现出一种不规则状态．与气候因子的相关性分析结果表明，晚粳稻试验点品种×地点 互作效应与１０月份（灌浆成熟期）的平均日照和平均气温有较大的相关性．从总体趋势上看，气 温和日照与试验点互作效应呈负向相关关系．
Based on the regional experimental yield data and the climatic data of the relevant experimental sites from years of paddy (early indica rice and late japonica rice), the trend of genotype × environment interaction structure change, the relationship with the main climatic factors and the average yield of the experiment were analyzed. Studies have shown that the rice genotype × environment interaction effect is relatively stable in the year, there is a relatively stable value. The interaction effects generated at the single pilot level also remained relatively stable during the year. The interaction effect of the pilot is composed of two parts: the fixed part (caused by soil and other factors) and the random part (caused by factors such as the uncertain climate). The two parts account for about 50% each. There is a good linear relationship between the experimental interaction and the estimated parameters (Dj parameters) of the ability of the pilot to discriminate the varieties, showing an irregular state with the pilot average output. The correlation analysis with climatic factors showed that there was a significant correlation between the interaction effect of variety × locality and the average sunshine and average temperature in October (filling maturity stage). From the overall trend, there is a negative correlation between air temperature and sunshine and experimental sites.
