中国新育油用亚麻品种（系）木酚素含量研究

 【目的】研究中国新育油用亚麻品种（系）木酚素含量与基因型和地点的关系。【方法】用高效液相色谱（HPLC）测定11个油用亚麻品种（系）2005、2006年在4个代表性试点的木酚素含量。【结果】11个亚麻品种（系）88点次木酚素含量变幅为6.487～13.127 mg?g-1，以97047平均含量最高，伊04的最低;4个地点中以河北坝上点最高，新疆伊犁点最低。方差分析表明，基因型、地点以及基因型×地点互作效应对木酚素含量的影响均达到1%显著水平。不同品种（系）木酚素含量的稳定性存在明显差异，以97047和伊04的稳定性好。【结论】基因型是影响木酚素含量的首要因子，品种选育是提高木酚素含量的首选措施。不同品种有不同的适种地区，参试品种（系）中97047为木酚素含量高且适应性广泛的品种（系）。

Evaluation of Lignan Contents of Newly Bred Flax Varieties (Lines)in China

【Objective】 This study is to determine the relative contributions of genotypes and the interactions between genotype and location on variation of lignan contents in flaxseeds. 【Method】 Using HPLC, lignan contents of eleven flax varieties planted at four representative locations in 2005 and 2006 were determined. 【Result】 The results showed that lignan contents ranged from 6.487 to13.127 mg?g-1 of 11 varieties planted in 88 locations. The highest content was found in line 97047, and the lowest in line Yi 04. In the four locations tested, Bashang in Hebei Province gave the highest total lignan contents, and the lowest contents were from those grown in Yili of Xinjiang. Genotype, location and interactions between genotype and location have significant influence on variation in lignan contents in all varieties. The stability of lignan content in different varieties also differed significantly. Lines 97047 and Yi 04 showed high stability. 【Conclusion】 Genotype is the most important factor that affects the lignan content in flaxseed, therefore it would allow for an improvement of lignan contents by breeding. Different varieties have different feasible planting areas. Line 97047 contains the highest lignan content among all varieties tested. It is also adapted to a wide range of flax planting areas.
