摘    要: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。

关 键 词:品种×地点互作  AMMI模型  稳定性和适应性  气候因子

Abstract:Through the analysis of yield stability and adaptability of eleven rice varieties selected from the middle-late maturity group of Liaoning province rice regional trial in 2004 at eight trial units,the relationship between the Genotype×Environment interaction and climatic factors was studied.The results showed that there was a remarkable difference of rice yield between different varieties and spots.The results of AMMI model indicated that some varieties had special adaptability in a certain spot,such as Yutian202 at the Wangshuitai of Liaoyang and Dashiqiao Agricultural Technology Extension Center,Shennong 9866,Liaoyan188 and Liaoxing3 around Shenyang area,Liaoyou2006 in the Agricultural Science Station of Haicheng Xisi and Liaoning Salt Soil Research Institute, respectively;both the stability and adaptability of Liaojing294 and Shennong9765 were preferably.Among the climatic factors,the temperature and solar radiation were the main factors effected the Genotype×Environment interaction,and the adaptability to climatic factors was different among varieties,for example,Liaoyan188 had especial adaptability in the environment with lower temperature,Yutian202 have especial adaptability in the area with less solar radiation hours,and Liaojing294,Shennong9765 and Huajing8 were adaptable in most trial spots.
Keywords:Interaction of Genotype×Environment  AMMI model  Stability and adaptability  Climatic factor
