RAPD Analysis of Genetic Diversity for Leading Potato Varieties in Heilongjiang Province
The random amplified polymorphic DNA procedure (RAPD) was used to assess the genetic diversity for 34 leading potato varieties in Heilongjiang Province, which were to understand the genetic relationship of these leading potato varieties, and provide the theoretical basis for the breeding of potato varieties. The result showed that there were 135 polymorphic bands amplified with 34 primers, and the polymorphic rate was 73%;these 34 potato varieties were divided into three classes and seven subclasses, and the genetic distance among 34 potato varieties was ranged from 0.112 to 0.551, with an average of 0.364. These results suggest that the genetic similarity is high and the genetic base is narrow among leading potato varieties in Heilongjiang Province.
