安徽省早稻新品种(组合)区域试验

Regional Test of New Early Rice Varieties(Lines) of Anhui Province

[目的]鉴定安徽省选育或引进的早稻新品种(组合)在不同区域条件的丰产性、稳产性、适应性和抗逆性。[方法]依据省种子管理站要求,采取完全随机区组排列,3次重复进行田间试验。[结果]产量最高的为浙辐2306达7 575.0 kg/hm2,早籼276位居第2位达7 300.5 kg/hm2,位列第3的是直早038达6 987.0 kg/hm2,均比对照高;浙辐2306、早籼276、直早038的农艺性状、抗性等也较好。[结论]参加续试的品种浙辐2306、早籼276和直早038可进行生产性示范。

[Objective] The aim was to identify the high yielding,stable yielding,adaptability,and resistance to stress of some new early rice varieties（combinations） bred and introduced by Anhui Province under different regions.[Method] According to the requirement of seed management station,the field test was conducted on by randomized complete block design with three repeated.[Result] Zhefu 2306’s yield was the highest with 7 575.0 kg / hm2,the next was Zaoxian 276 with 7 300.5 kg/hm2,the third was Zhizao 038 with 6 987.0 kg/hm2,which were higher than that of control;and the agronomic traits and resistance of Zhefu 2306,Zaoxian 276 and Zhizao 038 were all better.[Conclusion] Among the tested rice varieties,Zhefu 2306,Zaoxian 276 and Zhizao 038 can be used to carry out the next production demonstration.
