본 연구는 우리나라와 중국 그리고 파키스탄에서 수집한 재래종 조 계통들에 대하여 형태적 특징에 의한 유전적 변이성 연구를 수행하였다. 그 결과 우리나라 및 중국, 파키스탄의 조 계통들은 다음과 같은 형태적 변이를 나타내었다. 1. 형태적 특성조사에 의하면, 우리나라에서 수집한 조 계통들은 중국과 파키스탄에서 수집한 계통들보다 출수기가 늦었고, 초장이 크고, 이삭이 긴 특성을 나타내었다. 반면에 파키스탄에서 수집한 계통들은 출수기가 빠르고, 초장이 작고,
To understand the morphological differentiation of the 26 accessions of Foxtail Millet collected in Korea (15 accessions), China (7 accessions) and Pakistan (4 accessions), we analyzed 9 morphological characteristics such as plant height, panicle length, leaf number, tiller number, heading time, seed weight and panicle color etc. Most accessions of foxtail millet collected in Korea showed late heading time, tall plant height and long conical panicles. While foxtail millet accessions of Pakistan showed early heading time, short plant height and short conical panicles. In case of Chinese accessions, some accessions of them showed similar characteristics with Korean accessions, and the other showed similar characteristics to Pakistan accessions. In ANOVA analysis, most of quantitative characteristics such as plant height, leaf number, internode number and heading time showed significant differences among foxtail millet accessions collected from Korea, China and Pakistan. Principal component analyses clearly discriminate foxtail millet accessions of Korea from those of China and Pakistan. In PCA analysis, most of quantitative characters such as panicle length, leaf number and internode number greatly contributed in positive direction, whereas several quantitative characters such as tiller number, seed weight and panicle color contributed in negative direction on the first axis. Thus, these morphological characteristics could be used to classify the foxtail millet accessions collected in Korea, China and Pakistan. The present results could expand our understanding of the morphological variation in foxtail millet accessions from Korea, China and Pakistan, and also could be useful for foxtail millet germplasm preservation.
