【摘要】 金花菜是南方地区重要的一年生苜蓿，可用作牧草、绿肥、健康蔬菜和地被景观植物等。本研究以新收集到的荚果无刺的金花菜为新品系（命名为‘川西’金花菜），以‘川西’金花菜原始群体和现有地方品种‘川南’金花菜为对照，按照国家草品种审定办法，开展金花菜品种比较试验，通过对参试品种的生物学特性和农艺性状进行比较，研究结果表明：‘川西’金花菜荚果无刺，粗蛋白含量达24%，干草产量13 086.16 kg/hm~2，种子产量1 171.15 kg/hm~2。该品种在南方草山草坡放牧地建植、人工草地建植、林下种草、植被恢复等方面具有良好的应用前景。更多还原

【Abstract】 Medicago polymorpha,an essential annual meidic in southern China,serves multiple purposes as forage,green manure,healthy vegetable,and groundcover landscape plant.This study introduces a new variety of spineless-podded Medicago polymorpha (designated as’Chuanxi’),with the original variety of Medicago polymorpha’Chuanxi’and the existing local variety Medicago polymorpha’Chuannan’serving as controls.Comparative trials of Medicago polymorpha varieties were conducted in accordance with national grass variety evaluation guidelines.By comparing the biological characteristics and agronomic traits of the participating varieties,the results reveal that Medicago polymorpha’Chuanxi’exhibits spineless pods,a crude protein content of 24%,a hay yield of 13 086.16 kg/hm~2,and a seed yield of 1 171.15kg/hm~2.This variety holds promising application prospects for the establishment of grazing lands on grassland slopes,artificial grasslands,understory planting,vegetation restoration,and other endeavors in southern China.更多还原
