摘要： ‘杂选1号’是中国农业科学院兰州畜牧与兽药研究所培育的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。‘杂选1号’苜蓿在甘肃旱作栽培条件下表现出良好的生产性能。在天水、兰州、定西不同生态条件下的区域试验结果表明，‘杂选1号’苜蓿在3个区试点的鲜草平均产量为46117.78 kg/hm2，比对照‘中兰1号’苜蓿高11.42%，比‘巨人’苜蓿高22.35%，比地方品种（天水、陇中）高28.82%。‘杂选1号’苜蓿在3个区试点的干草平均产量为12257.89 kg/hm2，比对照‘中兰1号’高19.40%，比‘巨人’苜蓿高23.54%，比地方品种（天水、陇中）高24.40%。‘杂选1号’苜蓿在3个区试点的种子平均产量为371.35 kg/hm2，比对照‘中兰1号’低8.95%，比对照‘巨人’苜蓿高11.85%；比地方品种（天水、陇中）高16.11%。

Abstract: The alfalfa of“Zaxuan No.1”is a new breeding strain of Lanzhou Institute of Husbandry and Pharmaceutical Sciences of CAAS, which is a drought endurance and high yield of a new strain alfalfa, suitable for growing cultivation in the semi-arid and semi-humid regions of Gansu and similar areas in Loess Plateau. The new strain breeding exhibited good production performance under dry farming condition in Gansu. The regional trial results showed that the average fresh yield of a new strain alfalfa was 46117.78kg/hm2 in Tianshui, Lanzhou and Dingxi, increased by 11.42% compared with control alfalfa of Zhonglan No.1 (Medicago sativa L.), higher than the control alfalfa of Juren (Medicago sativa L.) 22.35%, and higher than the local alfalfa of Tianshui or Longzhong (Medicago sativa L.) 28.82%.The average dry yield of new strain was 12257.89kg/hm2，increased by19.40% compared with control alfalfa of Zhonglan No.1, higher than the control alfalfa of Juren (Medicago sativa L.) 23.54%, and higher than the local alfalfa of Tianshui or Longzhong 24.40%.It’s seed yield was 371.35kg/hm2,lower than the control alfalfa of Zhonglan No.1 8.95%, higher than the control alfalfa of Juren 11.85%, and higher than the local alfalfa variety of Tianshui or Longzhong 16.11%..
