为研究寒地水稻产量的稳定性和对环境的适应性,利用AMMI模型分析了9个黑龙江省垦区水稻品系在8个不同生态点的产量情况和环境互作。最终通过结果得出结论,环境对产量的影响最大,其次是基因型与环境互作,基因型的影响最低。9个参试品种稳定性为农大1226>龙粳20(CK)>垦稻10-2883>农丰11-02>垦系09-36>垦稻10-507>垦10-599>农丰11-03>农大04-058,试验点中对产量的鉴别力为八五三农场>红卫农场>查哈阳农场>八五八农场>红旗岭农场>三江所农场>江滨农场>梧桐河农场。在调查品种与试验点的适应性中,得出垦稻10-507在八五三农场,农丰11-03在红卫农场,农丰11-02在查哈阳农场,垦10-599在八五八农场、江滨农场和梧桐河农场表现出最佳适应性。
In order to study the stability of winter rice yield and its adaptability to the environment, the AMMI model was used to analyze the yield and environmental interactions of rice lines in eight different ecological sites in nine Heilongjiang reclamation areas. Finally, the conclusion is drawn from the results that the environment has the greatest impact on the yield, followed by genotype-environment interaction with the lowest genotype impact. The stability of 9 tested cultivars was Nongda 1226> Longjing 20 (CK)> Kenting 10-2883> Nongfeng 11-02> Kenren 09-36> Ken rice 10-507> Ken 10-599> Nongfeng 11 -03> Nongno 04-058, the discriminating power of the experiment at the experiment site is 835 Farm> Hongwei Farm> Chahayang Farm> 858 Farm> Hongqiling Farm> Sanjiang Farm> Jiangbin Farm> Indus River farm. In the investigation of the adaptability of varieties and test points, come Kennamen 10-507 in the 853 Farm, Nongfeng 11-03 in Hongwei Farm, Nongfeng 11-02 in Chahayang Farm, Ken 10-599 in Eight hundred fifty-eight farms, Riverside Farm and Indus River farms showed the best adaptability.
