Abstract

To detect morphological diversity and morphotypes in Astragalus membranaceus var. mongholicus cultivated in Longxi county, 11 main biological characters of 210 individuals were investigated and subjected to principle component analysis and cluster analysis. Multivariate analyses showed that the tested individuals of A. membranaceus var. mongholicus have been divergent in some biological characters, especially in pod colour, seed maculation, and stem colour, which resulted in 3 main morphotypes, namely R type, RG type, and G type. It is suggested that the population of A. membranaceus var. mongholicus in Longxi county is heterogenous.
