Advances in the Study on the Genetic Relationships of Pinus yunnanensis and Its Related Species

Germplasm resources are very important for the breeding study.Research on the genetic relationships of Pinus yunnanensis and its related species can provide scientific basis for exploring the origin,evolution,classification,breeding and application.The research advances in genetic relationship of P.yunnanensis and its related species,including the morphological,cytological characters,isozyme and molecular biology,were reviewed in this paper.And the prospect of study about the genetic relationships between Pinus yunnanensis and its related species was discussed.
