摘要：

为北方苦荞生产中提供合理利用‘晋荞麦2号’的依据，根据2006—2008年度国家苦荞品种（北方组）区域试验和2008年度国家苦荞生产试验资料，采用方差分析和新复极差测验法、高稳系数法、结合产量变异系数和适应度对品种进行丰产稳产性分析。结果表明，在2006—2008年国家苦荞品种（北方组）区域试验中和2008年国家苦荞生产试验中，‘晋荞麦2号’平均产量分别为2006.0 kg/hm2和2152.5 kg/hm2，分别比统一对照‘九江苦荞’增产13.3%和24.4%；高稳系数分别为39.80%和5.4%，均小于对照‘九江苦荞’；产量变异系数分别为41.58%和38.85%，均小于对照‘九江苦荞’；适应度分别为48.7%和100%，均高于对照‘九江苦荞’。由此得出，‘晋荞麦2号’是一个丰产稳产性高、适应性强的中熟苦荞新品种，具有较好的广适性，品质好，适宜加工各种苦荞保健产品和进行产业化开发，在中国北方苦荞种植区具有良好的应用前景。

Abstract:

The aim was to provide the basis for the rational utilization of ‘Jinqiaomai2’ in the tartary buckwheat in the north of China tartary buckwheat planting area. Using method analysis of variance and New multiple range test method, high stability coefficient method, combining with the coefficient of variation of the yield and adaptability degree, high yield stability of varieties was analyzed. In the 2006-2008, tartary Buckwheat region test of Country (Northern China) and tartary buckwheat production test of Country in 2008, the average yield of ‘Jinqiaomai2’ were 2006.0 kg/hm2 and 2152.5 kg/hm2, increasing by 13.3% and 24.4% than that of the control. Their high stability coefficients were 39.80% and 5.4%, being all lower than that of the control. Their yield variation coefficients were 41.58% and 38.85%, being all lower than that of the control. Their fitness were 48.7% and 100%, being all higher than that of the control. ‘Jinqiaomai2’ is a high and stable yield and high adaptability new tartary buckwheat varieties, has wide adaptability, good quality, suitable for processing all kinds of tartary buckwheat health products and the industrialization of development, has a good application prospect in the north of China tartary buckwheat planting area.
