摘　　要：对北京地区引种的11个多叶型苜蓿Medicago sativa品种产量、叶茎比、鲜干比、再生速度及营养成分等生产性能指标进行了系统研究,并经过综合分析可得,各试验材料都表现较好,作为主要指标的干草产量都超过了13 t/hm2,粗蛋白含量超过了20%,其中Forerunner、DK127、DK134和DK124综合表现突出,可作为优先考虑的优质高蛋白多叶型苜蓿推广示范品种。Productive performance indexes such as hay yield, leaf-stem ratio, dry-fresh ratio, regenerative speed and nutritious component of 11 multifoliar alfalfas had been studied in the trial for selecting better multifoliar alfalfa varieties in Beijing. Result of comprehensive analysis showed that all material exhibited good production in the trial, the main index as hay production was all over 13 t/hm^2 a year and protein component over 20%. Forerunner, DK127.DK134 and DK124 had comprehensive performance better than other materials and can be extended preferentially as better high protein multifoliar alfalfa in Beijing.
