摘要
Genetic characters of 10 soybean breeds in Heilongjiang Province were studied using RAPD technique. We calculated the genetic similarity and genetic distance, made the cluster analysis, and also studied the genetic relationship among the 10 breeds. We found 93 amplification segments by RAPE） analysis, in which there were 70 polymorphism segments, 75.26% of amplification segments, using 13 random primers, 11, 12, 5, 4, 7, 8, 3, 7, 2, 5, 10, 10, 9 amplificated bands were found. There were 7.15 bands per primer in average, The genetic similarity among the breeds ranged from 0.6848 to 0.9019, and the genetic distance ranged from 0.0981 to 0.3152. Genetic relationship between 90035 and 9674 was the closest, and between Heifeng 27 and 90035 was the farthest. Protein analysis revealed that the closest genetic relationship was between 90035 and 90024, and the farthest was between 1330 and Sui 4, and between 1330 and Heinong 39.
