| Abstract: | The genetic diversity,comprehensive coefficient of variability of 12 traits and the geographical distribution of 6172 accessions collected from China were studied by quantitative genetics in this paper.It showed that:① Annual wild soybean in 42～47°N×122°E plots are the richest in accessions,genetic diversity and comprehensive coefficient of variability.②Annual wild soybean in 34～35°N×113～115°E,38～39°N×113～115°E and 34～35°N×107～1090°E of Yellow River Valley and Qinling Mountains take second place.③ The genetic diversity and comprehensive coefficient of variability of annual wild soybean were higher in 26～27°N×119～121°E of southeast coast, but the distribution of accessions was less.The genetic diversity centers, spread modes of genetic diversity were put forward according to the distribution of accessions, genetic diversity and comprehensive coefficient of variability.From this the origin mode of wild soybean in China was inferred.The results provided an evidence for origin of cultivated soybean in China. |
