Abstract
对山西省苦荞品种资源的分布区域、主要农艺性状和营养成分进行分析,开展苦荞资源研究,对筛选优异苦荞种质资源和改良苦荞品种具有重要的指导意义。利用Excell 2003和 DPS 7.5软件,从品种资源的分布区域、主要农艺性状和营养成分含量3个方面,对《山西省农作物品种资源目录》和《中国荞麦品种资源目录》记载的山西省苦荞品种资源进行了统计分析。结果表明:山西省各地均有苦荞种植,但不同苦荞品种在生育期、株高、主茎节数、主茎分枝数、单株粒重和千粒重性状上存在着明显差异,表现出苦荞地方品种资源的多样性。山西省苦荞资源的蛋白质和脂肪含量平均值高于全国平均水平,维生素PP含量平均值与全国平均水平相当,而维生素E含量平均值低于全国平均水平;微量元素Ca、 Mg、 Cu、P和Se等含量极为丰富, Fe、 Mn和Zn等含量亦较高;含有的18种氨基酸中谷氨酸含量最高,色氨酸含量最低。并采用欧氏距离,利用类平均法对调查材料进行了系统聚类分析。通过对《山西省农作物品种资源目录》和《中国荞麦品种资源目录》中保存的苦荞资源进行分析,对不同的品种资源进行了分类,育种工作者可以选择具有互补性状的种质资源,通过杂交育种途径,选育出丰产、优质、抗逆的新品种。
The purpose of this paper was to lay a foundation for researchers to select excellent buckwheat germplasm resources and improved buckwheat varieties.Tartary buckwheat recorded in the books Catalogue of Gops Germplasm Resources in Shanxi Province and Catalogue of Chinese Buckwheat Germplasm Resources were analyzed by Excel 2003 and DPS 7.5 from the aspects of distribution area, main agronomic traits and nutritional ingredients.The results showed that local buckwheat varieties have diversity.Different varieties of buckwheat vary in plant height, node numbers of the main stem, grain weight per plant, grain weight per plant and 1000-grain weight.Compared with national average value, buckwheat in Shanxi is higher in protein and fat, but lower in vitamin E and same in vitamin PP.Buckwheat is rich in Ca, Mg, Cu, P, Se, Fe, Mn, Zn.Buckwheat contains 18 kinds of aminophenol with highest content of glutamic acid and lowest content of tryptophane.After analyzing and classifying tartary buckwheat germplasm resources recorded in Catalogue of Gops Germplasm Resources in Shanxi Province and Catalogue of Chinese Buckwheat Germplasm Resources, breeders can use these germplasm resources to crossbreed and then breed new varieties with high yield and quality and strong adverse resistance.
