AB  - Birch (<i>Betula platyphylla</i> Suk.), distributed in Eurasia, North America, and Australia, is a kind of cold-resistant, fast-growing, and vital pulpwood tree species. It is also one of the most important ecological restoration tree species with high values of economic benefits in Northeast China. To improve the genetic gain and expand the economic benefit of <i>B. platyphylla</i>, many genetic improvements have been carried out. In China, <i>B. platyphylla</i> is widely distributed and varied, and there are many varieties with excellent genetic characteristics. In this paper, the genetic improvement of <i>B. platyphylla</i> was reviewed, and the previous research results were discussed from two aspects: conventional breeding and molecular breeding. Some problems and corresponding solutions in the genetic improvement were put forward to provide ideas for <i>B. platyphylla</i> breeding in the future.
