为筛选出适宜甘肃半干旱区荞麦产区会宁县种植的荞麦品种，丰富荞麦品种类型，促进荞麦产业可持续发展，对引进的20个荞麦品种进行比较试验，并对荞麦主要农艺性状、产量、品质进行比较与分析。结果表明，10个甜荞品种中，以定甜荞1号产量最高，为979.6 kg/hm2，较参试甜荞品种平均产量增产40.31%；其单株粒重5.83 g、粗蛋白含量156.13 g/kg、总黄酮含量5.56 mg/g，均为参试甜荞品种中最高。10个苦荞品种中，以定苦荞1号产量最高，为1 861.5 kg/hm2，较参试苦荞品种平均产量增产89.10%；其株高99.9 cm、主茎节数22.8节，均为参试苦荞品种最高；分枝数19.0个、单株粒重7.75 g、总黄酮含量27.63 mg/g，均较高。大甜1号和云荞1号综合性状好，产量较高，分别为845.5、1 633.4 kg/hm2；大甜1号总黄酮(4.26 mg/g)、粗脂肪含量(22.96 g/kg)均较高，千粒重(41.86 g)显著高于其他参试甜荞品种；云荞1号淀粉含量(795.67 mg/g)高于其他参试苦荞品种，粗蛋白含量(166.43 g/kg)较高。综上所述，可将定甜荞1号、定苦荞1号作为优选品种在甘肃半干旱区及相似生态区示范推广；可将大甜1号作为大粒专用型品种、云荞1号作为高淀粉专用型品种在甘肃半干旱区及相似生态区示范推广。

To identify buckwheat variety suitable for cultivation in the buckwheat production area of Huining County, enrich buckwheat variety types, and promote sustainable development of the buckwheat industry, 20 introduced buckwheat variety were subjected to comparative experiment, and their major agronomic traits, yield, and quality were analyzed. Results showed that among the 10 sweet buckwheat varieties, Dingtianqiao 1 had the highest yield of 979.6 kg/ha, which was 40.31% higher than the average yield of the tested sweet-buckwheat variety. Its single-plant grain weight(5.83 g), crude protein content(156.13 g/kg), and total flavonoid content(5.56 mg/g) were all the highest among the tested sweet buckwheat variety. Among the 10 tartary buckwheat varieties, Dinkuqiao 1 had the highest yield of 1 861.5 kg/ha, 89.10% higher than the average of the tested tartary buckwheat varieties. Its plant height (99.9 cm) and number of main-stem nodes (22.8) were the highest, its branch number (19.0), single-plant grain weight (7.75 g), and total flavonoid content(27.63 mg/g) were also relatively high. Datian 1 and Yuntian 1 had good overall traits and relatively high yields of 845.5 and 1 633.4 kg/ha, respectively. Datian 1 showed high total flavonoid content(4.26 mg/g) and ether extract content(22.96 g/kg), and its thousand-grain weight(41.86 g) was significantly higher than other tested sweet buckwheat varieties. Yuntian 1 had a higher starch content(795.67 mg/g) than other tested tartary buckwheat varieties and relatively high crude protein content(166.43 g/kg). In conclusion, Dintianqiao 1 and Dinkuqiao 1 can be recommended as preferred variety for demonstration and promotion in the temperate semi-arid region of Gansu and similar ecological zones. Datian 1 can be used as a large-grain specialized type, and Yuntian 1 as a high-starch specialized type for promotion in the same regions.
