| 摘 要： | 为了给青稞品质育种提供参考,采用国际通用的混合键β-葡聚糖分析方法测定了195份青稞种质的(1→3),(1→4)-β-葡聚糖含量,结果显示,测定材料的平均β-葡聚糖含量为5.10％,变化范围为3.03％～7.16％;有21份材料的含量高于6％,1 5份材料低于4％,可分别用于食用、饲用和酿造用品种的育种.青海省18个育成品种(系)的β-葡聚糖含量变化范围为3.68％～6.48％,昆仑2号和昆仑10号β-葡聚糖含量分别高达6.23％和6.49％,05-鉴12和09-鉴16的β-葡聚糖含量最低,分别为3.77％和3.68％.不同棱形、粒色和粒重的种质之间β-葡聚糖含量无显著差异.

| Abstract: | Beta glucan contents of 195 hull less barley genotypes with different origins were determined using a mixed linkage assay. The mean content of all genotypes was 5.10%, ranging from 3.03%~7.16%. Among them there were 21 genotypes with beta glucan content higher than 6%, and 15 genotypes lower than 4%, and they could be used in breeding for food and beer varieties, respectively. The beta glucan content of 18 cultivars developed in Qinghai ranged from 3.68%~6.48%, with Kunlun 2 and Kunlun 10 being 6.23% and 6.49%, and with 05 Jian12 and 09 Jian16 being 3.77% and 3.68%, respectively. There was no significant difference in beta glucan content among different row types, grain colors and grain weights. |
