Abstract:

The genetic improvement of Masson pine (Pinus massoniana) in China started in the 1950s, comprehensively developed in the late 1970s and early 1980s, and rapidly advanced with the integration of post-modern biotechnology in the new century. In this review, we comprehensively summarized the research work (including provenance trials, superior tree selection, establishment of seed production stand and seed orchard, clone selection, wood properties improvement, and modern biotechnology-assisted breeding), major achievements, innovation, and leading role and contribution to society of the Nanjing Forestry University Group on Masson pine over the past 60 years. Additionally, the improvement experience is summarized. Facing new opportunities and challenges, and in view of the characteristics of the species, existing research basis and social needs, and development trend in the field of biology, we suggest that the genetic improvement of Masson pine in the future should be based on the work of germplasm resources, multi-objective selection and breeding, family and clone forestry needs, and integration of conventional and modern biotechnology. More attention should be given to the breeding fields of pine wood nematode-resistant, pulp making, and high-yield turpentine varieties, and basic and advanced research and its integration into conventional breeding. The above research will be beneficial to the genetic improvement of this tree species.

Key words: Masson pine(Pinus massoniana), genetic improvement, research review and prospect, achievement, strategic response
