Abstract

Morphological variation associated with the geographical distribution of 75 accessions of common millet collected in Korea, Japan, and China (54, 12 and 9 accessions, respectively) was evaluated. Morphological characteristics of the accessions were investigated using two quantitative traits (plant height and days from seedling to flowering) and two qualitative traits (seed color and inflorescence shape). Most traits did not show significant differences between accessions from the three countries; however, in the case of plant height, the accessions from Korea and Japan were similar in size whereas the accessions from China were shorter. The first and second principal components of a principal components analysis of the four traits accounted for 76.6% of the total variation (52.2% and 24.4%, respectively). Seed color, inflorescence shape, and days from seedling to flowering characterized the first axis in the positive direction. Seed color characterized the second axis in the positive direction whereas inflorescence shape, plant height, and days from seedling to flowering characterized this axis in the negative direction. Principal components analysis of morphological characteristics did not clearly distinguish between common millet accessions from Korea, Japan, and China. This study provides useful information for understanding the morphological variation associated with the geographical distribution of common millet accessions in East Asia.
