摘要

花冠草是一种原产于地中海地区的珍贵药用植物。近年来，冠状螺旋体(G. coronaria var. discolor)已被提升为G. discolor (d 'Urv .)。根据形态特征，将其与冠状花序(G. coronaria var. coronaria)区分开来。良性)。为了研究这种多样性的遗传基础，我们利用AFLP标记对地中海3个不同地区(意大利、西班牙和葡萄牙)的G. discolor和G. coronaria的基因型进行了分析。结果表明，在5个引物组合鉴定的1347个片段中，99.55%为多态性。遗传距离和香农指数表明，这两个物种在遗传上是可以区分的，但需要进一步的研究来证实这一假设。

Preliminary assessment of genetic diversity between Glebionis coronaria and G. discolor (Asteraceae) by AFLP markers

Glebionis coronaria is a valuable and medicinal herb native of Mediterranean region. Recently, G. coronaria var. discolor has been elevated to the rank of species as G. discolor (d’Urv.) Cano based on morphological characteristics, distinguishing it from G. coronaria var. coronaria (=G. coronaria). To investigate the genetic basis of this diversity, AFLP markers were applied to genotypes of G. discolor and G. coronaria sampled in three different Mediterranean regions (Italy, Spain, and Portugal). Our results showed that among 1347 fragments identified with five primer combinations 99.55 % were polymorphic. The genetic distance and the Shannon Index values suggested that the two species can be genetically distinguished, but further studies are needed to confirm this hypothesis.
