龙胆草品种选育通常根据其生长发育状况并以高产作为目标实施群体选育,而品质育种没有可见的参考依据。能否通过表型性状确定品质优劣从而进行单株选育或特征类型群体选育是品质育种希望解决的问题。对采自2个地区100余份龙胆草进行表型性状分类并分级赋值,分别测定了样本中龙胆苦苷、獐牙菜苷、獐牙菜苦苷、熊果酸、齐墩果酸5种有效成分的含量,并分析了表型性状与有效成分之间的相关性。初步研究表明,龙胆草茎色、叶色等性状与龙胆苦苷等主要成分含量之间存在一定的相关性,可为以后的龙胆草株选或特征类型筛选提供参考。
Selection of gentian varieties is usually based on their growth and development status and high yield as the target population breeding, and quality breeding no visible reference. The question of whether quality breeding can be solved by the ability of single plant breeding or population selection of characteristic types through the determination of the quality of phenotypic traits. Genomic traits of more than 100 Gentiana from two regions were classified and graded. The contents of gentiopicroside, swertia glycoside, swertiarin, ursolic acid, oleanolic acid 5 kinds of active ingredients, and analyzed the correlation between phenotypic traits and active ingredients. Preliminary studies have shown that Gentian stem color, leaf color and other properties and gentiopicroside and other major components of the content of a certain correlation between the gentian can be selected for the future or feature type screening provide a reference.
