基于110份来源于世界各地的亚麻(Linum usitatissimum)资源(栽培品种和育种材料)和1个野生近缘种L.bienne,利用AFLP技术研究形态学上不同的亚麻,即纤维亚麻和油用亚麻的遗传多样性。聚类分析结果表明,L.bienne明显区别于其他样品,自展值高;纤维亚麻与油用亚麻和不明用途亚麻也能区别开来,但自展值偏低。主成份分析显示,纤维亚麻与油用亚麻区别明显,但L.bienne与油用亚麻之间难以区别,荷兰、法国的纤维亚麻与其他国家的纤维亚麻亦可明显区别,这说明亚麻基因库出现了类群结构。分子方差分析显示,纤维亚麻的变异度低于油用亚麻及不明用途亚麻,因此,油用亚麻和野生亚麻L.bienne是丰富纤维亚麻基因库的潜在种质资源。
Based on 110 Linum usitatissimum resources (cultivars and breeding materials) and one wild relative L. bienne from different parts of the world, AFLP was used to study morphologically different varieties of flax and oil flax Genetic diversity. Cluster analysis showed that L. bienne was significantly different from other samples and had a high self-spreading value. Fiber flax, oil flax and unidentified flax were also distinguishable, but the value was low. The principal component analysis showed that the difference between fiber flaxseed and oil flaxseed is obvious, but it is difficult to distinguish between L.bienne and oil flax. Fiber flax in Holland and France can also be obviously distinguished from fiber flax in other countries, which indicates that flax gene bank appears The taxon structure. Molecular variance analysis showed that the variation of fiber flax was lower than that of oil flax and unidentified flax. Therefore, oil flaxseed and wild flax L. bienne were potential germplasm resources for the rich fiber flax gene pool.
