Abstract: Great progress has been made in the genetic improvement and seed production of masson pine through the cooperative researches during the last 3 Five Year Plans of China. In this paper we briefly review the major achievements including geographic variation and provenance selection, establishment of production population and breeding population, vegetative propagation and clonal forestry, directional selection of industrial timber, breeding strategy and some basic research items,emphatically discuss and analysize the existing various problems in the researches and production practices on provenance study and extension,breeding zone development,protection and utilization of superior gene resources, techniques for seed orchard establishment and seed production, pulp wood selection, resistance breeding, genetic parameter estimate, genotype by environment interaction,early selection, breeding plan and programme etc., and put forward certain views to benefit the future breeding of masson pine in China.
