摘要
对来自甘肃省种质资源库的46个胡麻品种资源按甘肃地方品种、国内育成品种和国外品种进行分类,分析研究不同类型及同一类型不同品种籽粒中木酚素含量、粗脂肪含量及5种主要脂肪酸的含量,以了解胡麻品种资源品质特性,为合理高效利用资源,提高胡麻优质育种效率奠定基础。结果表明:①籽粒的木酚素、粗脂肪、棕榈酸、硬脂酸、油酸、亚油酸、亚麻酸含量的变化范围广,说明不同胡麻品种资源的主要品质性状存在显著差异。②国外品种的木酚素含量、亚麻酸含量均最高;国内育成品种与国外品种的粗脂肪含量均较高,但国内育成品种亚麻酸含量最低;甘肃地方品种的木酚素含量、粗脂肪含量均最低。③筛选出具有特异优质品质性状的资源4份。④相关性分析表明,木酚素与亚油酸含量呈显著正相关,硬脂酸与粗脂肪和不饱和脂肪酸含量均呈极显著相关,油酸与粗脂肪含量,亚油酸和亚麻酸含量之间呈极显著负相关。
Based on a total of 46 flax samples of Gansu landraces,improved cultivars and exotic cultivars,the lignan content,fat content and five kinds of fatty acids were analyzed.The results showed： ① The range content of the lignan,fat,Palmitic acid,Stearic acid,Oleic acid,Linoleic acid and Linolenic acid of flax cultivars is wide.The content of these main quality characters have significant difference.② In the 3 kinds of flax cultivars,the content of lignan and Linolenic acid are the highest in the exotic cultivars;the fat content is high both in the improved cultivars and the exotic cultivars,but Linolenic acid content is the lowest in the improved cultivars;the content of lignan and crude fat are the lowest in Gansu landraces.③ 4 cultivars which have some special characteristics were selected to be used in flax breeding.④ The correlations of the quality characters showed： the content of lignan were significantly positively correlated with the linoleic acid,while Stearic acid content was significantly correlated with the fat content and unsaturation fatty acids,and the content of Oleic acid was significantly negatively correlated with Gansu landraces;with fat content,Linoleic acid and Linolenic acid.
