The Study On Specific Property Of Genetics Of Soybean Variety (Stran) In Heilongjiang Province

This work has researched the genetic characters of 10 soybean variety in Heilongjiang province by RAPD technique, calculated the genetic similar and genetic distance, made the cluster analysis, studied the genetic relationship among the 10 variety.The results of RAPD analysis is found 93 amplification segments and 70 polymorphism segments, is 75.26% in all of, in the aberrance DNA among 10 soybean variety making RAPD amplification to utilized the 13 random primer. It is found the genetic variations among the 10 variety, there are :11, 12, 5, 4, 7, 8, 3, 7, 2, 5, 10, 10, 9 bands amplificated . from 10 variety with 13 random primer and the average 7.15 bands per primer. The genetic similar among the variety changed in 0.6848to 0.9019, the genetic distance changed in 0.0981 to 0.3152, and the breed change most is Heilongjiang 10 and 90035,the smallest is found in 90035 and 9674, the closed genetic relationship is between 90035 and 9674,and the farthest is between Heifeng 10 and 90035.The results of Protein analysis is found that the closed genetic relationship is between 90035 and 90024,and the farthest is between 1330 and Sui 4, the farthest is between 1330 and Heinong 39.
