本工作的目的是表征亚麻籽（Linum usitatissimum L.）基因型分为具有高和低α-亚麻酸（ALA）含量的组。在32个亚麻籽基因型中，高α-亚麻酸基因型占68.75%，低ALA基因型占31.25%。根据规范实现了脂肪酸的比例代表性（捷克标准、计量和测试办公室，1994年）。根据Agritec Ltd.的内部方法分析油含量，根据规范（捷克标准、计量和测试办公室，2011年）。在所有组内分析的种子样品中，总脂肪含量范围为36.22%至46.35%，ALA含量范围为1.10%至65.20%，亚油酸（LA）含量范围为11.10%至75.00%。基因型也根据种子颜色进行了划分，并观察到这些组内所有三个参数之间的线性相关。证实了参数之间的负线性依赖性;各组中的ALA和LA含量：高ALA棕色种子（p < 0.0001;相关系数（r）= -0.70）和高ALA黄色种子（p < 0.001; r = -0.36）。此外，在低ALA棕色种子组（p < 0.001; r = 0.34）和低ALA黄色种子组（p < 0.0001; r = 0.62）中，发现总脂肪与LA含量之间存在正线性相关。
The aim of our work was to characterize linseed (Linum usitatissimum L.) genotypes divided into groups with high and low content of alpha-linolenic acid (ALA). Out of 32 linseed genotypes, 68.75 % represented high alpha-linolenic genotypes and 31.25 % were genotypes with low ALA content. Proportional representation of fatty acids was realized according to the norm (Czech Office for Standards, Metrology and Testing, 1994). Oil content was analyzed according to the internal methodology of Agritec Ltd., based on the norm (Czech Office for Standards, Metrology and Testing, 2011). The content of total fat ranged from 36.22 % to 46.35 %, that of ALA from 1.10 % to 65.20 %, and that of linoleic acid (LA) from 11.10 % to 75.00 % in the analyzed seed samples within all groups. The genotypes were divided also according to the seed color and a linear correlation between all three parameters within these groups was observed. Negative linear dependence was confirmed between parameters; ALA and LA content in the groups: high ALA brown seed (p < 0.0001; correlation coefficient (r) = -0.70), and high ALA yellow seed (p < 0.001; r = -0.36). Also, positive linear dependence between the total fat and the LA content in the groups: low ALA brown seed (p < 0.001; r = 0.34); low ALA yellow seed (p < 0.0001; r = 0.62), was found.
