| 摘 要： | 对选育的鹅观草(Roegneria kamoji)新品系——都江堰鹅观草和川农2号鹅观草，以国审品种“赣饲1号” 纤毛鹅观草(R.ciliaris cv. Gansi No.1)为对照，在四川成都平原上进行牧草生产性能和适应性试验。经连续3年的品种比较试验表明，都江堰鹅观草和川农2号鹅观草干草产量分别为20 973 和21 831 kg·hm-2，显著高于对照(P＜0.05)，分别比对照增产19.9%、24.8%。新品系生育期比对照长17～27 d，粗蛋白质含量达11.68%，且高抗锈病和白粉病。鹅观草可作为山地和丘陵地区种植的优质牧草资源和水土保持植物。

| Abstract: | Roegneria kamoji perennial species in Triticeae and hexaploidy (2n=6x=42) with the StYH genomes.In this study,the yields of two new varieties of R.kamoji——Dujiangyan and Chuannong No.2 were reported with cultivated variety (R.ciliaris Gansi No.1) as control.Three years experiment showed that the hay yield of R.kamoji Dujiangyan and R.kamoji Chuannong No.2 were 20 973 and 21 831 kg·ha-1,respectively,which increased by 19.9% and 24.8%,respectively,compared with the cultivated variety R.ciliaris Gansi No.1.Furthermore,the two new varieties had longer growth period and higher protein content than those of R.ciliaris Gansi No.1.All of these improvements suggested that the two new varieties of R.kamoji could be used as forage grass in upland areas. |
