选用自行开发引物的、具有较高遗传多态性的8个微卫星位点，分析来自独立的3株开花毛竹半同胞家系各50个子代个体。结果表明：位于3个不同地点的开花植株都能够通过与外源花粉杂合产生具有不同的微卫星基因型特点的半同胞家系子代，各个家系子代内均存有一定的遗传多样性，估算的平均异交率约为0.089。这说明毛竹主要以自交为主，并兼顾有一定比例的异交以确保其后代种群的遗传多样性。

Mating system is the basic property of plant populations and biological foundation for germplasm preservation as well as genetic improvement. In this study we applied developed 8 microsatellite loci with high polymorphism to analyze 50 half-sib progenies from each of 3 independent flowering culms of Phyllostachys edulis. The results showed that flowering culms in three different locations were fertilized with foreign pollen,which generated progenies with different microsatellite genotypes and genetic diversity. The overall estimates of outcrossing rate tm of single-locus and ts of multi-locus for the three culms were 0. 089,indicating that the reproductive system of P. edulis predominantly involved in self-fertilization with a certain proportion of outcrossing to produce genetic diverse progenies. This is the first report so far on estimation of outcrossing rate for monopodial bamboo species such as P. edulis by DNA molecular markers.
