To better understand the genetic diversity and relationships of the two cultivated types of Perilla crop and their weedy types in Korea and Japan, we evaluated the genetic variations of 56 accessions by assessing five morphological characteristics and 18 SSR markers. The two cultivated types of var. frutescens and var. crispa were clearly distinguished by seed size, whereas most accessions of cultivated and weedy types of var. crispa cannot be distinguished strictly by seed characteristics. A total of 165 alleles with the SSR analysis were detected with an average number of 9.2 alleles per locus among the 56 Perilla accessions. The number of alleles per locus ranged from two for KWPE-56 and KWPE-39 to 21 for GBPFM-204. Additionally, the genetic diversity of each locus ranged from 0.497 at KWPE-56 and KWPE-39 to 0.959 at GBPFM-204, with an average of 0.692. The average genetic diversity values were 0.549, 0.685, 0.451 and 0.557 for cultivated and weedy types of var. frutescens and for cultivated and weedy types of var. crispa, respectively. The weedy type accessions of var. frutescens and var. crispa evidenced greater variation than the corresponding cultivated type accessions. The accessions of the cultivated and weedy types of var. frutescens and var. crispa from Korea exhibited greater SSR diversity than those of Japan. An UPGMA phylogenetic tree revealed three major groups, which was congruent with their morphological characteristics except for a few odd accessions. SSR markers clarified the genetic relationships between var. frutescens and var. crispa and helped improve our understanding of the genetic diversity of the two cultivated types of P. frutescens and their weedy types in Korea and Japan.

In this study, 17 simple sequence repeat (SSR) primer sets were used to analyze the genetic diversity, geneticrelationships, and population structure among 81 accessions of two cultivated types of Perilla crop and theircorresponding weedy types in East Asia and other countries. A total of 166 alleles were identified with an averageof 9.8 alleles per locus. The average gene diversity (GD) value was 0.709. The average polymorphic informationcontent (PIC) value was 0.679. The GD of each locus for accessions of cultivated var. frutescens, weedy var. frutescens, cultivated var. crispa, and weedy var. crispa were 0.557, 0.740, 0.429, and 0.509, respectively. Bothweedy accessions exhibited higher GD and PIC values than their corresponding cultivated types. The cultivated and weedy types of the Perilla crop had much higher GD and PIC values in East Asia than in other countries. Particularly, in East Asia, the Perilla accessions from China showed higher SSR diversity than those from Korea, Japan, and other countries. Population structure analysis identified three groups, Group I, Group II, and an admixed group. Phylogenetic analysis produced four major clusters, but there was no clear geographic relationship between the two cultivated types of Perilla crop and their weedy types based on their regional distribution. This study demonstrated the utility of SSR analysis for performing genetic and population analysis of cultivated and weedy types of Perilla accessions in East Asia and other countries.
