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.
