应用 Ａ Ｍ Ｍ Ｉ模型分析了 １９９７ 年南方稻区晚粳品种区域试验的参试品种产量。结果表明：８ 个品种的产量超过对照秀水 １１， 增产幅度达 ０４％ ～１２１％ ， 其中镇稻 ５３２、７０ 优 ０４、９２１２、丙 ９３６３ 增产极显著；基因型×环境的互作平方和为品种平方和的 ２５ 倍， Ａ Ｍ Ｍ Ｉ２ 模型解释了互作平方和的 ７９９２％ ，鄂粳杂 １ 号、秀水 １１、７０ 优 ０４、华粳杂 １号、９２１２、丙 ９３６３ 和镇稻 ５３２ 的稳定性相对较好； 镇稻 ５３２、９２１２ 的适应性较广，产量不高稳定性不好的品种粳 ７９１在江苏南京、上海有效利用了互作，表现出特殊适应性。 The A M M I model was used to analyze the yield of the tested varieties in the regional trials of late japonica rice varieties in southern rice in 1997. The results showed that the yield of 8 cultivars exceeded the control Xiushui 11 and the yield was up to 04% ~ 121%. Among them, the yields of Zhenzao 532,70, 04,9212 and 9363 increased significantly; genotype × The sum of the squares of the interactions of the environment is 25 times of the square of the varieties. The A M M I2 model explains 7992% of the sum of squares of interactions, Ejingzaza 1, Xiushui 11,70 You 04, Huajingza 1 No. 92,12, 93 93 and the stability of the town of rice 532 is relatively good; town of rice 532, 92 12 wide adaptability, yield is not high stability of the poor variety japonica 791 in Nanjing, Jiangsu, Shanghai Effective use of the interaction, showing special adaptability.
