裸燕麦品种(系)丰产性和适应性评价

Evaluation of high yield and adaptability of naked oats(lines)

【目的】明确2003—2014年国家裸燕麦区域试验品种(系)的丰产性和适应性,并划分适宜种植区域,为品种的推广提供依据。【方法】采用标准差(standard deviation of means,SD)校正的GGE双标图(SD-GGE)法,对4轮试验、30个裸燕麦参试品种在21个试点的丰产性和适应性进行分析。【结果】方差分析表明,环境是影响产量变化的主要因素,环境变异占总变异的47.53%~83.95%。GGE双标图分析表明,9418、坝莜10号、蒙燕2号和张莜7号为在参试的大部分试点中产量较高的品种;4轮试验中山西省五寨县试点品种籽粒丰产性顺序与所有试点平均产量排序基本相同。【结论】9418、坝莜10号、蒙燕2号和张莜7号为丰产性和适应性较强的品种;山西省五寨县试点的代表性较好。

【Objective】The high yield and adaptability of varieties(lines)participating in the naked oats regional test in China from 2003 to 2014 were determined,and suitable planting sites were devided to provide a basis for the promotion of the varieties.【Methods】The standard deviation of means(SD)corrected GGE-Biplot(SD-GGE)method was used to evaluate the high yield and adaptability of 4 rounds of trials and 30 naked oat varieties in 21 pilots.【Results】The analysis of variance showed that the environment was the main factor affecting yield changes,accounted for 47.53%-83.95%of the total variation.On the GGE-Biplot,9418,Bayou No.10,Mengyan No.2 and Zhangyou No.7 were higher yields in most of the pilots tested.In all 4 rounds of trials,the high yield of all varieties in the Wuzhai County in Shanxi Province was basically the same as the order of the average yield of all the experimental sites.【Conclusion】9418,Bayou No.10,Mengyan No.2 and Zhangyou No.7 were high yield and strong adaptability varieties.Wuzhai County in Shanxi Province was a good respresentative of all the sites.
