摘　　要：以豆科牧草大翼豆[Macroptilium atropur—pureum（de．）urb cu．Siratro]为材料，通过单株选择，培育出优质高产的豆科牧草大翼豆06—2[M．atropur—pureum（de．）urb cu．Siratro No．06—2]，并对其进行品种比较试验和区域试验。结果表明，大翼豆06—2适应性广，抗寒，耐轻霜，丰产性能好，年平均鲜草产量高达42822．0kg／hm^2，比对照品种高20．3％～33．3％。此外，大翼豆06—2生长速度快，蛋白质含量高达19．0％，具有较高的营养价值，有望成为亚热带地区的优良豆科牧草品种。An eminent leguminous grass of Macroptilium atropur- pureum （dc.） urb co. Siratro No. 06-2 was bred with M. atropur - pureurn （dc.） urb co. Siratro by individual plant selection. And then the variety test and regional test were carried out between M. atropur - pureum （dc.） urb co. Siratro No. 06-2 and other grasses. The results showed that M. atropur - pureum （dc.） urb cv. Siratro No. 06-2 had wide adaptability, cold resistance,light frost resistance, efficient bi- ological nitrogen fixation, high yield and strong competitivity. The average annual yield of fresh grass was 42822.0kg/hm^2. which was 20.3% to 33.3% higher than that of reference varieties. In addition, M. atropur - pureum （dc.） urb co. Siratro No. 06-2 grew fast and had high protein content （19.1%）. These results suggest that M. atropur - pureurn （dc.） urb co. Siratro No. 06- 2 has high nutritive value and it is an eminent leguminous grass in subtropical areas.
