- Abstract
To better understand the morphological variation in the 189 accessions of cultivated var. frutescens of Perilla crop preserved at the RDA-Genebank in South Korea, morphological characteristics were investigated using seven traits related to leaf quality. In the principal component analysis (PCA), the first and second principal components accounted for 28.9% and 19.7% of the total variance, respectively. In the first component, leaf color (QL1) and stem color (QL3) contributed positively, whereas the flowering period (QL5) and degree of pubescence (QL6) contributed in a negative manner. In the second component, QL5 and QL6 contributed positively, whereas the fragrance of plants (QL7) contributed negatively. The results of PCA showed that the 189 Perilla accessions were clearly divided into three groups based on the 1st axis (X-axis), except for some accessions. However, the Perilla accessions collected in South Korea and abroad did not show a clear geographical distribution between the collection areas. Correlation analysis among the seven traits of 189 Perilla accessions showed a positive correlation coefficient for the combination of QL1 and QL3, and QL5 and QL6, and a negative correlation for the combination of color of the reverse side of the leaf and QL6, and QL5 and QL7. Therefore, the results of this study will provide useful information for the selection of useful resources for the development of leafy vegetable varieties of the Perilla crop and the preservation and management of genetic resources of the Perilla crop preserved at the RDA-Genebank in South Korea.
