摘　　要：通过对18个国内外苜蓿品种的鲜草产量、株高、花期等农艺性状进行田间观测及统计分析,结果表明:国外品种与国内品种相比不存在生产性能优势;国内的"公农1号"与"龙牧803"2个苜蓿品种产量最高;农艺性状间存在一定的相关性;其中鲜草产量与株高、花期早晚、越冬情况、抗倒伏能力密切相关。By the field measurement and statistics analysis of the traits of 18 domestic and overseas alfalfa varieties, including yield, plant height ,bloom time etc, the result showed： The overseas alfalfa varieties are not better than the domestic ones about yield; The yield of ＂GongNong No.l＂and ＂LongMu803＂ is in the top two. There is some correlation among the agronomic traits .There is some correlation among yield, plant height, bloom time, winter surviving and lodging resistance.
