Abstract

In this study, we detected the morphological variation of
91 Perilla accessions from Northern and Southern China by the
measurement of 7 quantitative and 10 qualitative characters. The
accessions of cultivated var. frutescens were significantly different from
accessions of weedy var. frutescens and cultivated and weedy types of
var. crispa in 7 quantitative traits such as plant height (QN1), internodes
(QN2), the number of branches (QN3 and QN4), length of the largest
inflorescence (QN5), the number of florets (QN6) and flowering time
(QN7) etc. In addition, significant differences were found between
accessions of cultivated var. frutescens from northern and southern areas
of China for 7 quantitative traits. However, there were no significant
differences between accessions of cultivated and weedy types of var.
crispa. In principal components analysis (PCAs), 5 quantitative traits and
4 qualitative characters contributed in the positive direction on the first
axis. 2 quantitative and 6 qualitative characters contributed in the
negative direction on the first axis. The accessions of cultivated and
weedy types of var. crispa were clearly separated from accessions of
cultivated and weedy types of var. frutescens in the PCAs. In addition,
most accessions of cultivated var. frutescens from Northern China were
discriminated from accessions of cultivated and weedy types of var.
frutescens from Southern China. These findings in this study will assist
to better understand the morphological variation for two cultivated types
of Perilla crop and their weedy types according to the geographical
distribution in northern and southern areas of China.
