[RAPD study of populations of Glycine tabacina].
The ecological genetic research on Glycine tabacina populations was based on RAPD technique, which revealed 100% polymorphisms, with minimum value of 0.41 in population MM, and maximum value of 0.82 in population PT. Cluster analysis showed that the populations' genetic variation was correlation to the environment gradient when the geographic distance among populations was big. In small geographic range,however, no correlation exists between genetic structure and ecological factors because of random genetic drift.
