Development and Application of Molecular Markers Related to Purple Leaf in Brassica Juncea
To identify the genotype of purple-leaf and green-leaf mustards,the parental lines of purple-leaf mustard ZiYi and green-leaf mustard LvYi and their constructed F1 and F2 populations were used as research materials.Using molecular marker technology,the differences of BjPur gene between the parents were studied,and two pairs of leaf color-specific molecular markers were developed.These molecular markers were further used to identify the genotypes of eight purple-leaf and red-leaf mustards.The results showed that these molecular markers could be used to rapidly distinguish the genotypes of different leaf color materials in mustard.
