초록

This study was conducted to provide basic information on the variation for the sesame
breeding using principal component analysis and cluster analysis based on phenotypic diversity of the
growth characters and yield components of 27 sesame germpalsm collected from Korea, Russia, USA,
China, Japan, and Uzbek. At the result of principal component analysis, sesame germpalsm was
grouped into three main components which accounted for 94.6% of the total variation. The first principal
component (Z1) positively correlated with plant height, height to first capsule and capsule length. The
second principal component (Z2) positively correlated with days to flowering and maturity. At the scatter
diagram, Haenam, Andong, Alkae2, Cali and Ulzin were included group I in which those germpalsm
could be used as sesame breeding materials relating to increasing stem length and the number of capsule
per plant. In Group II, Alkae1, Sangju, Yeongpoong and Black were included and used as breeding
materials for the improvement of days to flowering and maturity. The dendrograms were classified
about twelve groups by applying single linkage method. Yeongil was the most separated from the other
germpalsm, followed by S1 and Sangju. Otherwise, Whazun and Ju6 showed minimum distance.
