摘要
通过采用GGE双标图方法分析了2017-2018年国家冬油菜品种区域试验长江中游区参试品种的丰产性、稳产性、适应性及各试点的试验代表力、鉴别力和区分能力。结果表明,参试品种的基因型效应、环境效应、基因型与环境互作效应均达极显著水平,4组试验平均环境效应占处理平方和的48.25%,基因型效应占15.15%,基因型与环境互作效应占36.60%。利油杂178、创杂油16号、中油769、华油杂706、中油619、圣光168、渝油39和景油517等品种具有良好的丰产性、稳产性和适应性,在湖南衡阳、常德、岳阳和湖北荆州等试点综合评价值较高,有较强的试点代表力、鉴别力和区分能力。
The high yield,stable yield and adaptability of the national winter rape variety regional test in the middle reaches of the Yangtze River from 2017 to 2018,and the test representative,discrimination and differentiation ability of each pilot were analyzed by using the GGE double plot method.The results that the main effects of genotype(G),environment(E)and genotype by environment interaction(GE)were significant.Among them,E accounted for 48.25% of the treatment total variation in the sum of squares on average,whereas G and GE accounted for 15.15%and 36.60%,respectively.Liyouza178,Chuangzayou No6,Zhongyou 769,Huayouza 706,Zhongyou 619,Shengguang 168,Yuyou 39 and Jingyou 517 had excellent high yield,stability and adaptability.Hengyang city,Changde city,Yueyang city of Hunan province,Jingzhou city of Hubei province and other pilot sites have high comprehensive evaluation values,and have strong pilot representative,discrimination and differentiation ability.
