在分析2004年辽宁省中晚熟区试中11个水稻品种在8个不同试点产量稳定性和适应性的基础上,探讨了品种×地点互作与气候因子的相互关系。结果表明:不同品种、不同地点产量差异极显著;AMMI模型结果指出雨田202在辽阳望水台、大石桥市农业技术推广中心,沈农9866、辽盐188及辽星3号在沈阳周边地区,辽优2006在海城市西四农科站、辽宁省盐碱地利用研究所具有特殊的适应性;而辽粳294和沈农9765的稳定性和适应性都比较好。影响品种×地点互作的主要气候因子是温度和日照,且不同品种对气候因子的适应性也不同,如辽盐188对温度较低的环境有特殊适应性,雨田202对日照时数较少的环境有特殊适应性,而辽粳294、沈农9765和花粳8号却适应大多数的环境。
On the basis of analyzing the stability and adaptability of 11 rice cultivars tested in mid-late maturity region in Liaoning Province in 2004, the interrelationship between cultivar × spot interaction and climatic factors was discussed. The results showed that there were significant differences in yield between different varieties and locations. The results of AMMI indicated that Yutian 202 was located in the surrounding area of Shenyang in Wangsitai, Liaoyang, agricultural technology promotion center of Dashiqiao, Shennong 9866, Liao salt 188 and Liao Xing 3, Liaoyou 2006 had special adaptability in Xici Agricultural Station of Haicheng City and the utilization of saline-alkali land in Liaoning Province. However, the stability and adaptability of Liaoyou-294 and Shennong 9765 were better. The main climatic factors influencing species × site interaction are temperature and sunshine, and the adaptability of different species to climatic factors is also different. For example, Liaoyu 188 has special adaptability to lower temperature environment and Yutian 202 has less sunshine hours Of the environment have special adaptability, and Liaojing 294, Shennong 9765 and flower japonica 8 adapt to most of the environment.
