摘要
为培育适宜沿江、江淮地区种植的粮(籽粒)和草(饲草)产量及品质优良的大麦新品种,对12份多棱饲用大麦新品系和对照品种西引二号的饲草和籽粒的产量及品质进行比较,运用灰色关联度分析法进行综合评价。结果表明,B11015-1干草产量显著高于大部分自育品系,但与对照差异不显著;多个自育品系的籽粒产量高于对照,其中B11015-7籽粒产量最高;B11015-7和B11015-3饲草粗蛋白含量较高,分别为7.96%和7.82%;B11015-2和B11015-14相对饲喂价值(RFV)较高,分别为159.15和157.14;B11015-3和皖饲2-1籽粒蛋白质含量较高,分别为10.33%和10.03%。采用灰色关联度分析,以10个性状指标对参试品种(系)进行综合评价,初步认为B11015-3、B11015-1、B11015-2和B11015-14等4个自育品系优于对照,可能成为沿江、江淮等地种植的粮、草兼用多棱饲用大麦材料。
In order to breed elite barley varieties suitable for planting along the Yangtze River and Jianghuai regions with good forage and grain yield and quality, 12 multi-rowed barley lines were compared with Xiyin No.2(control variety, CK) and evaluated through grey correlation analysis. The results showed that the hay yield of B11015-1 was significantly higher than most of other lines, but had no significant difference with CK. The grain yield of several lines was higher than CK, among which B11015-7 had the highest grain yield. B11015-7and B11015-3 had higher crude protein contents of 7.96% and 7.82%, respectively, while B11015-2 and B11015-14 had higher relative feeding value(159.15 and 157.14, respectively). B11015-3 and Wansi 2-1 had higher protein contents(10.33% and 10.03% respectively). Grey correlation analysis based on ten selected traits revealed B11015-3, B11015-1, B11015-2 and B11015-14 were superior than CK. Therefore, the selected four lines are elite barley materials for planting in Yangtze River and Jianghuai regions to harvest forage and grain.
