【 摘 要 】
The plant-type variation in 56 Japanese native cultivars of common buckwheat (Fagopyrum esculentum Moench) was investigated. Eleven quantitative characteristics, such as main stem length, the lengths of the 1st order branches at the 2nd, 3rd, and 4th nodes, the number of nodes, the numbers of the 1st, 2nd and 3rd order branches, total number of branches, the number of flower dusters and the node position of the lowest flower, positively correlated with each other, and these characteristics positively correlated with the growth duration. The ratio of branch length to main stem length positively correlated with the angle between the main stem and the 1st order branch. In the principal component analysis based on 15 quantitative characteristics, the first component mainly related with plant size and the scores correlated with the growth duration. The second component related with the plant shape became more variable as the score of the first component increased. There was a significant variation in the plant types of native cultivars collected in western Japan. Thus, it is suggested that the native cultivars from western Japan have various plant types.【 授权许可】
