摘　　要：秋季种植12个非秋眠和半秋眠紫花苜蓿品种,以播种当年的生长表现以及第二年春季和初夏期间的生物量、株高、分枝、蛋白质含量等性状的观察来进行综合评价,结果表明:各品种分枝数在春季最高,其中WL903、WL656、赛迪7和WL525第一次刈割时的分枝数和三次累计分枝数均最高;WL656、赛迪7、赛迪10和WL903第一次刈割产量和累计产量最高;而赛迪10、赛迪7、WL656、WL903和Weston单位面积蛋白质产量最高。综合分枝、产量、株高和蛋白质产量4个性状指标,12个苜蓿品种中以WL656、赛迪7、赛迪10和WL903的综合评分相对较高,速生性和蛋白质产量均比较高,适宜在长江下游冬闲田种植。Twelve non-fall dormancy and semi-fall dormancy Medicago sativa varieties were planted in winter fallow land of south-east China in the autumn.The comprehensive evaluation for the twelve alfalfa varieties were conducted from aspects of biomass,height,branches,protein content,and other traits during the following spring and early summer.The results showed that branches number of different alfalfa varieties were the highest in the early spring.The varieties of WL903,WL656,Saidi 7 and WL525 had the highest number of branches in first cutting and accumulated branch number of three cutting.The varieties of WL656,Saidi 7,Saidi 10 and WL903 had the highest biomass production both in the first cutting and accumulation of three cutting; while varieties of Saidi 10,Saidi 7,WL656,WL903 and Weston had the highest protein yield both in the first cutting and accumulation of three cutting.Based on comprehensive evaluation of branches,biomass yield,height and protein yield,varieties of WL656,Saidi 7,Saidi 10 and WL903 were suitable for planting in winter fallow land of lower Yangtze River in south China.
