摘　　要：为了培育适宜于在甘肃半干旱和半湿润地区及黄土高原类似区域栽培的耐旱、高产紫花苜蓿新品系,试验采用多点同时进行的方法开展生产试验。结果表明:杂选1号新品系的干草产量平均为10 573.00 kg/hm2,高于对照品种中兰1号12.13%,比对照品种陇中苜蓿高17.87%,比甘肃地方品种天水苜蓿高18.60%;种子产量低于对照品种中兰1号10.36%,高于对照品种陇中苜蓿14.67%,高于甘肃地方品种天水苜蓿30.17%。To breed a new drought - tolerant and high - yield alfalfa line which was suitable for cultivation in the semi - arid and semi - humid regions of Gansu and similar areas in Loess Plateau. The multiple simultaneous methods were used to carry out the production trials. The results showed that the average hay yield of the new alfaffa line of Zaxuan No. 1 was 10 573.00 kg,/hm2, which was 12.13 % higher than that of Zhong- lan No. 1 （Medicago sativa L. ） as the control, 17.87% higher than that of Longzhong （Medicago sativa L. ） as the control, and 18.60% higher than that of Tianshui （Medicago sativa L. ） as the local variety in Gansu. Its seed yield was 10.36% lower than that of Zhonglan No. 1 （Medicago sativa L. ） as the control, but 14.67% higher than that of Longzhong （Medicago sativa L. ） as the control, and 30. 17% higher than that of Tianshui （Medicago sativa L. ） as the local variety in Gansu.
