摘　　要：为了评价不同亚麻品种(系)在氮利用效率方面的差异,筛选出氮高效利用的亚麻种质资源,在大田试验条件下,以25份亚麻品种(系)作为试验材料,设置2个处理,分别为不施氮肥(N0)和施氮肥(N18),分析亚麻工艺长度、株高、全麻率、原茎产量、纤维产量及其与氮利用效率相关性。结果表明:施用氮肥有利于提高亚麻工艺长度、株高、全麻率、原茎产量和纤维产量;经过聚类分析,N0条件下,筛选出氮高效利用的种质资源1份,黑亚16;N18条件下,筛选出氮高效利用的种质资源5份,分别是原2012-297-1、双亚12、双亚10号、New和原2012-283;N0条件下,氮利用效率与工艺长度、株高、全麻率、原茎产量和纤维产量正相关,但未达到显著差异水平,N18条件下,氮利用效率与株高、全麻率和纤维产量显著正相关(P<0.05),与工艺长度呈极显著正相关(P<0.01)。In order to evaluate the difference of nitrogen use efficiency among different flax varieties（lines）and screen nitrogen high efficiency utilization germplasm resources, under field condition, with two nitrogen levels（N0 and N18）, 25 flax varieties （lines） were used to investigate technical length, height, fiber content, straw yield,fiber yield and the correlation with nitrogen use efficiency. The results showed that nitrogen had a significant improvement on technical length, height, fiber content, straw yield and fiber yield of flax. One nitrogen high efficiency utilization germplasm resources were screened out（Heiya 16）under NO condition, five nitrogen high efficiency utilization germplasm resources were screened out （Yuan 2012-297-1,Shuangya12, Shuangya10, Yuan 2012-283 and New） under N18 condition by cluster analysis. Under NO condition,nitrogen use efficiency had a positive correlation but not significant with technical length, height, fiber content, straw yield and fiber yield, under N18 condition, nitrogen use efficiency had a significant positive correlation with height （P〈0.05）, fiber content（P〈0.05） ,fiber yield （P〈0.05） and technical length （P〈0.01）. The results would provide theoretical basis for investigation of nitrogen high efficiency utilization mechanism and breeding nitrogen high efficiency utilization varieties.
