为了筛选出适宜在天水市种植的籽用大麻品种(系)，以当地主栽品种清水大麻为对照，对引进大麻品种(系)的生育期、主要性状、产量等进行研究。结果表明，参试品种(系)出苗期基本相同。不同品种(系)种子折合产量有较大差异，沁源6号最高，达1 076.82 kg/hm2，比对照品种清水大麻增产41.17%；固原1号次之，为895.40 kg /hm2，比对照品种清水大麻增产17.39%，其余品种(系)均表现为减产。纤维折合产量沁源6号最高，达316.30 kg/ hm2，比对照品种清水大麻增产0.18%，其余品种(系)均低于对照品种清水大麻。原茎折合产量固原1号最高，达1 057.78 kg/hm2，比对照品种清水大麻增产39.39%；其次是沁源6号，为902.22 kg/hm2，比对照品种清水大麻增产18.89%。从主要性状和产量综合分析，沁源6号和固原1号表现较佳，适宜在天水市种植。

In order to screen out the seed hemp varieties(lines) suitable for planting in Tianshui, the growth periods, agronomic characters, yields, etc. of the introduced hemp varieties (lines) were tested with the local main cultivar Qingshui hemp as the control. The results showed that the tested varieties(lines) had basically the same period of emergence. The average seed yields of different varieties(lines) varied greatly, yield of Qinyuan 6 was the highest which was 1 076.82 kg/ha and was 41.17% higher than that of the control. Yield of Guyuan 1 ranked the second which was 895.40 kg/ha and was 17.39% higher compared with that of the control. Yield of the rest of the tested varieties (lines) were all declined compared with that of the control. Average fiber production peaked in Qinyuan 6 which was 316.30 kg/ha and was 0.18% higher than that of the control whereas average fiber production of the rest of the tested varieties (lines) were all lower compared with that of the control. Average stem production peaked in Guyuan 1 which was 1 057.78 kg/ha and was 39.39% higher compared with that of the control, Qinyuan 6 ranked the second in the average stem yield which was 902.22 kg/ha and was 18.89% higher than that of the control. Comprehensive analysis based on main agronomic characters and yields showed that Qinyuan 6 and Guyuan 1 were ideal in production performance and were considered suitable for planting in Tianshui.
