中文摘要：

为亚麻优良基因型的筛选及其品种的大面积推广，对12份黑龙江省当地主栽亚麻品种和10份新引进国外亚麻品种的田间农艺性状、经济技术指标进行综合比较研究。结果表明：引进亚麻品种D1ANE纤维和种子产量较高，黑亚23的平均纤维产量比DIANE高出0．0928t·hm^2，但其种子产量不及DIANE（相差0．1299t·hm^-2）。新引亚麻品种ARAMIS不论是纤维产量还是种子产量都高于当前主推品种，其经济效益较黑亚23和DIANE分别高584和918元·hm^-2。因此，新引亚麻品种ARAMIS生产潜力巨大，可以适当加大其大面积种植推广力度。

英文摘要：

In order to screen the fine genotype and expand the planting area of flax, a comprehensive compara- tive study on agronomic characters, economic and technical index was made on 12 main flax varieties in Hei- longjiang province and 10 new flax varieties introduced from abroad. The results showed that the fiber and seed yield of introduced flax variety DIANE were higher, and the average fiber yield of Heiya 23 was higher than DIANE for 0. 092 8 t·hm^-2 , but the seed yield was less than DIANE 0. 129 9 t·hm^-2. The new introduced vari- ety ARAMIS were higher than the current main varieties both in fiber and seed yield, its economic benefits was higher by 584 and 918 RMB per hectare than Heiya 23 and DIANE respectively. As a result, the production potential of new flax variety ARAMIS was tremendous, it would be a feasible plan to increase its intensity of large planting promotion appropriately.
