Abstract:

The authentic identification of seed and seedling in the closely related tree species is a very difficult problem in the forest tree seed and seedling of inspection. The research proceeding and the related information in this area are reviewed in this paper.On these bases,the authores discuss how to develop species-specific molecular markers to distinguish closely related tree species:one method is to develop species-specific SNPs markers according to the difference of the homogenous genes or loci in different tree species,the other is to develop species-specific STS or SCAR markers due to the specific genes or loci fixed in different tree species in the evolution progress.The species-specific molecular markers developed by these two methods can be used directly in forest tree seed inspection.

Key words: Forest tree seed inspection, Species-specific molecular markers
