Fig. 3

PCA-plot of 7 quantitative characters in 8 representative germplasms selected in Fig. 2, which were divided into four groups according to their SL, SW, PE, and SY. We randomly selected two different germplasms in each group to make PCA-plot, and they can be divided into four groups, too. The result was the same as the diagram. Group 1 contained M. astroites and M. fischeriana; Group 2 contained M.sativa and M. rigidula; Group 3 contained M. radiata and M. cretacea; Group 4 contained M. intertexta and M. ciliaris.
