摘　　要：引进甜荞(Fagopyrum esculentum Moench.)种质资源77份,进行农艺性状的田间鉴定,以期筛选出适宜内蒙古呼包地区种植的优异种质资源。结果表明,遗传性变异度以产量和单株粒重最大,变异系数分别为37.1%、38.5%,一级分枝数、单株粒数、第一侧枝长、茎壁厚、株高的变异系数较大,分别为36.6%、33.9%、32.4%、29.4%、21.9%,表明这些性状有丰富的遗传变异;通过对12个农艺性状的聚类分析表明,77份甜荞品种可分为3类,包括矮秆型21份、大粒高产型34份、高秆抗倒型22份;与产量显著相关的性状为单株粒重、千粒重、单株粒数(P<0.01)。综合来看,筛选出适于内蒙古呼包地区种植的兼具矮秆、高产、抗倒性状的优异甜荞种质资源9份。77 germplasm resources of sweet buckwheat(Fagopyrum esculentum Moench.)were introduced for field identification of agronomic characters,in order to screen excellent germplasm resources suitable for planting in the Hohhot-Baotou area of Inner Mongolia.The results showed that the yield and grain weight per plant had the highest genetic variability,with variation coefficients of 37.1%and 38.5%,respectively.The variation coefficients of the first branch number,grain number per plant,first lateral branch length,stem wall thickness and plant height were relatively high,with variation coefficients of 36.6%,33.9%,32.4%,29.4%and 21.9%respectively.It indicated that these traits had abundant genetic variability.Cluster analysis of 12 agronomic traits showed that 77 sweet buckwheat germplasm resources could be divided into 3 categories,including 21 short-stalk varieties,34 large-grain and high-yield varieties and 22 high-stalk and lodging-resistant varieties.The traits significantly related to the yield of buckwheat were grain weight per plant,1000-grain weight and grain number per plant(P<0.01).Nine excellent germplasm resources of sweet buckwheat with dwarf,high yield and lodging resistance were screened out,which were suitable for the climatic conditions in the Hohhot-Baotou area of Inner Mongolia.
