摘　　要：为选育适宜苏南丘陵区种植的紫花苜蓿Medicago sativa品种,引种18个育种材料,跨越一涝一旱2个极端年份,通过产量、抗病性、越夏性等多个指标的综合比较,筛选出适应性较强的Rampage、中苜1号、MF 3个育种材料,RS在干旱环境下表现优异。同时试验表明苜蓿在苏南丘陵区可获得较高产量,但必须应对高温高湿的夏季和易涝易旱的贫瘠土壤。To select adaptable alfalfa variaties for south Jiangsu hilly area, we seeded 18 alflafa breeding materials. Through the comparison of yield, disease resistance, and summer performance during two extreme years： one excessively moist and another drought, we selected three excellent materials. Rampage, Zhongmu NO. 1 and MF. In addition, RS had good performance under drought condition. The experiment also proved that alfalfa planting in this area could get high yields, but it must face high temperature, high moisture, and poor soil which can be easily waterlogged or dried.
