Abstract:

The morphological characteristics of 44 Chinese kale accessions were investigated and the DNA polymorphism was analyzed by randomly amplified polymorphic DNA (RAPD) marker. Twenty primers selected from 150 primers amplified a total of 177 bands, of which 105 were polymorphic, with an average of 7.0 bands and 3.8 polymorphic fragments per primer. The polymorphic percentage was 59.32%. The dendrogram based on RAPD data was constructed by NTSYS-pc2.1. Cluster analysis showed that 44 Chinese kale accessions could be divided into six groups at the level of D=0.70. Because Chinese kale was from south China and the main area was in south China, the genetic diversity of Chinese kale was smaller than other Brassica vegetables.
