Evaluating Varieties and Test Sites in the 2017 Rice Regional Trials of Hubei Province by GGE Biplot Based on Genstat

为分析水稻区试参试品种的丰产性、稳产性、适应性以及区试地点的代表力和鉴别力,采用Gen Stat软件中的GGE双标图对湖北省2017年水稻区试A组12个参试品种和10个区试地点进行了分析。结果表明,深两优10号、亮两优1212、隆晶优4393、襄优5327产量较高,亮两优1212、隆晶优4393、聚两优639、深两优10号具有较好的稳产性,襄优5327稳产性较弱,但在生产上仍有推广利用的价值。区试地点沙洋县、黄冈市、孝南区的代表力和鉴别力较强。

To analyze the high yield, stability production and adaptability performance of rice varieties and the representativeness and discrimination of test sites in regional trials, the GGE biplot based on Genstat was employed to identify 12 varieties from 10 test sites of A group in the 2017 rice regional trials of Hubei province. The results showed that, ‘Shenliangyou10＇,‘Liangliangyou1212＇, ‘Longjingyou4393＇ and ‘Xiangyou5327＇ had higher yield; ‘Liangliangyou1212＇, ‘Longjingyou4393＇,‘Juliangyou639＇ and ‘Shenliangyou10＇ had better stability production performance; The yield of‘Xiangyou5327＇was high while its stability was low, which still had application value for production. Shayang, Huanggang, and Xiaonan had the greater representativeness and discrimination.
