Background

Information on the genetic variation of genetic resource collections is very important for both the conservation and utilization of crop germplasms in genebanks. Var. frutescens of Perilla crop is extensively cultivated in South Korea as both an oil crop and a vegetable crop.

Objectives

We used SSR markers to evaluate the genetic diversity, genetic relationships, and population structure of 155 accessions of var. frutescens that have been selected as genetic resources for the development of leaf vegetable cultivars and preserved in the RDA-Genebank collection from South Korea.

Methods

A total of 155 accessions of var. frutescens of Perilla crop collected in South Korea were obtained from the RDA-Genebank of the Republic of Korea. We selected 20 SSR markers representing the polymorphism of and adequately amplifying all the Perilla accessions.

Results

The average GD and PIC values were 0.642 and 0.592, respectively, with ranges of 0.244–0.935 and 0.232– 0.931. The genetic variability in the southern region of South Korea was higher than that in the central region. The clustering patterns were not clearly distinguished between the accessions of var. frutescens from the central and southern regions of South Korea.

Conclusion

These results regarding the genetic diversity and population structure of the 155 accessions of var. frutescens of South Korea provide useful information for understanding the genetic variability of this crop and selecting and managing core germplasm sets in the RDA-Genebank of the Republic of Korea.

基于SSR标记的韩国紫苏种质资源遗传多样性和种群结构评估

背景

关于遗传资源收集的遗传变异的信息对于保护和利用种质库中的作物种质都非常重要。变体 在韩国，紫苏作物的frutescens被广泛种植为油料作物和蔬菜作物。

目标

我们使用SSR标记来评估155个var种的遗传多样性，遗传关系和种群结构。frutescens已被选作叶片蔬菜栽培品种的遗传资源，并已保存在韩国的RDA-Genebank藏品中。

方法

共有155个var。紫苏的紫苏来自韩国的RDA-基因库，获得在韩国收集作物。我们选择了20个SSR标记，分别代表所有紫苏种质的多态性并充分扩增了它们。

结果

GD和PIC的平均值分别为0.642和0.592，范围为0.244-0.935和0.232-0.931。韩国南部地区的遗传变异性高于中部地区。在var的种质之间未明确区分聚类模式。来自韩国中部和南部地区的frutescens。

结论

这些结果涉及155个var种的遗传多样性和种群结构。韩国的frutescens为了解该作物的遗传变异以及选择和管理大韩民国RDA-Genebank中的核心种质资源提供了有用的信息。
