| Abstract: | The main phenotypic traits of 44 collected and preserved Brassica juncea germplasm resources were identified and clustered.The results showed that the distance coefficient among germplasm resources is ranged from 0 to 39.84.These germplasm resources were divided into 10 groups at the distance coefficient of 5.1.It was consistent with the traditional classification,and fully reflected the characteristics of the cultivar type.This research provided a material basis and theoretical basis for hybrid breeding of B.juncea. |
