摘要

Chinese wolfberry (Lycium spp.) is an important edible and medicinal plant, with a long cultivation history. The genetic relationships among wild Lycium species and landraces have been unclear for a number of reasons, which has hindered the breeding of modern Chinese wolfberry cultivars. In this study, we collected 19 accessions of Chinese wolfberry germplasm, and constructed the genetic relationship based on RAD-seq markers. We obtained 30.32Gb of clean data, with the average value of each sample being 1.596Gb. The average mapping rate was 85.7%, and the average coverage depth was 6.76 X. The phylogeny results distinguished all accessions clearly. All the studied landraces shared their most recent common ancestor with L. barbarum, which indicated that L. barbarum may be involved in cultivation of these landraces. The relationship of some landraces, namely the Ningqi' series, Qingqi-1' and Mengqi-1,' has been supported by the phylogeny results, while the triploid wolfberry was shown to be based on a hybrid between Ningqi-1' and a tetraploid wolfberry. This study uncovered the genetic background of Chinese wolfberry, and developed the foundation for species classification, accession identification and protection, and the production of hybrid cultivars of wolfberry.

Barbarum的最新常见的祖先，这表明L. Barbarum可能参与培养这些实体的培养。一些实体的关系，即宁QI'系列，清奇-1'和孟汽-1，'已经得到了系统发育结果，而三倍体枸杞被证明基于宁QI-1'和四倍体之间的杂交物枸杞。本研究发现了中国枸杞的遗传背景，并开发了物种分类，加入鉴定和保护的基础，以及枸杞杂交品种的生产。
