摘要:

回顾广西马尾松(Pinus masoniana Lamb)育种的历史和现状。针对当前马尾松遗传改良中普遍遇到的问题,提出马尾松育种近期和中长期的育种措施。认为马尾松在近、中期的育种应逐渐从传统的用材林为主转向以纸浆和脂用林为主,建议在育种策略上有相应的准备和转变。

Abstract:

A systematic review is made of status and history of Masson pine(Pinus massoniana Lamb) breeding in Guangxi. At present time, the ratio of improved variety of Masson pine used for afforestation is still low in Guangxi. The technical problem for high consistent seed production in seed orchard has not been resolved. In view of the frequently encountered problems concerning tree genetic improvement and the specific characteristic of Masson pine. Breeding strategy of Masson pine in short, medium and long terms has been discussed. Breeding targets in short and medium terms should be changed from developing traditional timber forest to developing pulp and resin forest, the breeding strategy must be prepared and changed.
