The gene pool of masson pine clones was constructed in Xinyi Forestry Research Institute of Guangdong Province. The results showed that the survival rate of nursery grafted on the mountain was higher than that of the anvil on the mountain, and the forest was neat. The plants grew fast and were easy to manage. The paper also briefly describes the purpose and significance of the construction of cloned Pinus massoniana genebank. It introduces the technical methods of building genebanks and the management measures. The growth of fine clones in high fat, timber and other provinces is also analyzed.
