摘要
以南方水稻区域试验１９９５ 年和１９９６ 年中籼迟熟组的产量数据为资料，采用朱军等［１］ 提出的统计分析方法分析产量的各项方差分量，及参试品种产量的稳定性表现。方差分析结果表明，地点效应是影响产量的最主要因素。其次是年份×地点、品种×地点的互作。参试品种产量均低于对照特三矮２ 号。此外，对不同地区选育、不同亲本配制的品种产量性状进行了线性比较，分析了各品种产量对环境指数的敏感程度和稳定性表现。
Variance components and the stability performance of yield were analyzed for mid season indica rice in 1995 and 1996 in southern China regional trial with the methods by Zhu Jun et al [1] .The results indicated that location effect was the main factor .So the choice of trial location was important.There also existed large year effects by location or genotype location interactions.All of the variety yield were lower than the check Tesanai 2.Besides,the yield traits of rice which came from different breeding units or different parents were compared.The sensitivity degree of yield to environmental index were analyzed.
