| 摘 要： | 为了挖掘和筛选高α-亚麻酸亚麻品种资源，在旱作条件下，对国内外收集到的15份高α-亚麻酸亚麻品种进行产量、经济性状、抗性、品质鉴定。结果表明， Ty-21产量最高，为4366.7 kg/hm2，处第1位，对照陇亚8号产量为4333.4 kg/hm2，处第2位， Ty-21比对照陇亚8号增产0.77％；其余13个参试品种产量在2200.0-3966.7 kg/hm2之间，均低于对照；产量降低幅度在8.46％-49.23％。各品种α-亚麻酸含量在55.32％-60.97％之间，对照陇亚8号α-亚麻酸含量为55.95％，有12个品种α-亚麻酸含量超过对照陇亚8号。其中山丹白、临夏白、266三个品种α-亚麻酸含量高达60％以上。 Ty-21α-亚麻酸含量达到59.59％，比对照陇亚8号高3.65个百分点。综合分析产量、品质、抗性等指标， Ty-21品种是一个综合性状表现优异的品种资源。

| Abstract: | In order to select the flax varieties with high α-linolenic acid , 15 flax varieties origina-ted from home and broad were chosen to study on yield , economic characters , resistance and quality -i-dentification under natural drought condition.The result showed the yield of Ty -21 was the highest , which was 4366.7kg/hm2, 0.77% higher than CK.Longya-8 （CK） ranked the second, which was 4333.4 kg/hm2.Other 13 flax varieties’ yield were between 2200.0 kg/hm2 to 3966.7 kg/hm2 , all low-er than CK with the reduction rate of 8.46-49.23%.The α-linolenic acid content of the 15 varieties were between 55.32%to 60.97%, and the control Longya 8 was 55.95%, lower than 12 flax varieties, and 3 varieties （ Shandanbai , Linxiabai and 266 ） were over 60%.Theα-linolenic acid content of Ty-21 was 59.59%, 3.65%higher than CK.Ty-21 was the excellent variety according to its comprehen-sive characters of yield , quality and resistance. |
