摘　　要：研究采用田间随机区组试验,比较了16个紫花苜蓿(Medicago sativa)品种在扬州地区的生产性能与品质,以期筛选出适合扬州地区气候条件的品种。结果表明,各材料间的生产性能差异较大,其中德宝平均生长速度最快,显著高于多叶王、苜蓿王、猎人河、盛世;爱菲尼特的干草产量最高,显著高于其他品种,其次为皋兰2号、三得利、多叶王;阿尔冈金的粗蛋白(CP)含量最高,但酸性洗涤纤维(ADF)、中性洗涤纤维(NDF)含量也较高,爱菲尼特CP含量仅次于阿尔冈金,但ADF、NDF含量显著低于阿尔冈金。综合评价,爱菲尼特的生产性能最好,其次为皋兰2号、三得利、多叶王,这几个半秋眠型品种较适于在扬州地区推广种植。In order to select Medicago sativa varieties for adapting to the local climate in Yangzhou region, an experiment of complete randomized block was conducted to compare the productivity and quality of sixteen varieties of M. sativa in the study. The results showed that under the same conditions of geographical, climatic and management, there were large differences among the M. sativa varieties. The fastest growth rate on average was Derby, which was significant higher than that of Leafy king, Alfalfa King, Hunter River and Flourish Age. The hay yield of Aifeinite was the highest and significant higher than that of others; and followed by GL0602, Sanditi and Leafy king. The highest CP content was Algonquin and the ADF and NDF contents of Algonquin were also higher. The second higher CP content was Aifeinite, while the ADF and NDF contents of Aifeinite were significant lower than that of Algonquin. Compared comprehensively, Aifeinite had the best production performance, and followed by GL0602, Sanditi and Leafy king. Thus, these semi-dormancy varieties （fall dormancy index=4 or 5） is more appropriate for local applications in Yangzhou region.
