摘要
为准确评价水稻区试品种稳产性和适应性,利用GGE双标图对 2019 年辽宁省中早熟区试 6 个试验点的 14 个参试品种的产量数据进行分析.结果表明,基因型(G)、环境及基因型与环境互作(GE)均对水稻产量存在极显著影响.6 个区试点可分为 3 个生态类型区,源粳2 号在所属的生态区表现最优.美锋稻 245、源粳 2 号和富禾稻258 属丰产稳产性较好的品种,为理想品种.区试点中开原市示范繁殖农场区分力最好,桓仁满族自治县种子管理站代表性最强,抚顺市种子管理站具有很好的区分力及较强的代表性,是较理想的区域试验点.
Abstract
To accurately evaluate the stability and adaptability of rice varieties,we analyzed the yield data of 14 participating varieties from six mid-early experiment sites of Liaoning Province using GGE-biplot in 2019.The results showed that genotype,environment and interaction between genotype and environment influenced rice yield very significantly.The six pilot areas can be divided into three ecological types,and Yuanjing 2 performed the best in its respective ecological areas.Meifengdao 245,Jingyuan 2,and Fuhedao 258 were ideal varieties for this experiment due to their high-yielding ability and good stability.Among the experimental pilots,Kaiyuan Demonstration and Multiplication Farm had the strongest discrimination,Huanren Manchu Autonomous County Seed Management Station had the best representativeness,and Fushun Seed Management Station had good discrimination ability and strong representativeness,making it an ideal regional experimental site for this experiment group.
