16个胡麻品种生产性能的综合评价

Comprehensive Evaluation on Production Performance of 16 Flax Varieties

应用灰色关联度分析法对晋北干旱半干旱地区引种的16个胡麻品种的14个生物学性状进行了分析与综合评价。结果表明,16个胡麻品种中综合生产性能表现较好的品种是同亚白1号、陇亚杂1号、轮选2号、NORLIN和宁亚14号;而US1662、繁峙胡麻、US2921、定亚23号和晋亚11号综合生产性能表现较差;各项生物学性状和生理生化指标的权重大小顺序为单株粒数>产量>亚麻酸含量>含油率>硬脂酸>千粒质量>株高>亚油酸含量>木酚素含量>粗脂肪含量>单株秆质量>棕榈酸含量>单株果数>单株粒质量。试验结果可为晋北干旱生态区胡麻育种和推广提供科学依据。

In this study,the 14 biological characters of 16 introduced flax varieties in arid and semi-arid area of northern Shanxi province were analyzed and evaluated by grey correlation analysis method.The results showed that Tongyabai 1,Longyaza 1,Lunxuan 2,NORLIN and Ningya 14 had better comprehensive production performance,whereas US1662,Fanshi flax,US2921,Dingya 23 and Jinya11 had poor comprehensive production performance.The weight order of the biological traits and physiological and biochemical indexes was grain number per plant>yield>linolenic acid content>oil content>stearic acid>1000-grain quality>plant height>linoleic acid content>lignan content>crude fat content>stem quality per plant>palmitic acid content>fruit number per plant>grain quality per plant.The results will provide scientific basis for flax breeding and extension in arid ecological area of northern Shanxi province.
