Genetic variations of 49 M. ruthenica wild gemplasm from seven different origin in Inner Mongolia.Twelve floral properties,including calyx diameter,coronary length,number of inflorescence flowers have been studied and investigated with morphological marcers. The results showed that M. ruthenica between material the magnitude of the coefficient of variation was the largest flower traits for inflorescence length,the variation coefficient of79. 12%. The variation of the smallest for the calyx diameter,the coef...
