The mating system of the natural population in Pinus bungeana was analysed by applying isozyme starch gel technology, and the outcrossing rates of multilocus was 0.451-0.522, which standed at lower level, were compared with other pines and was accordant to its lower gene flow and heterozygosity. The reasons leading to lower outcrossing rate are discussed. The genetic differentiation coefficient of family reached to 0.322, which was higher than that of population.
