马尾松造纸材的变异、遗传和选择育种策略

对马尾松造纸材遗传改良和选择育种已有研究成果进行综合阐述。在明确马尾松造纸材育种目标的基础上，系统阐述了其木材产量、木材质量和浆纸性能在种源、林分、家系、个体和个体内各层次的变异模式和规律，以及性状遗传、遗传相关和遗传稳定性等遗传参数。通过木材量质与浆纸性能的联合选择，确定福建西部、江西中南、湖南南端、广东西北和广西东南这个呈东北─西南走向的狭长区域是马尾松造纸材最优种源区，而江西崇义，广西岑溪，广东罗定、英德、韶关和福建永定则是其最佳产地。同时选择了一批生长、材质兼优的家系和个体。最后就马尾松造纸材选择育种策略和未来遗传育种研究的重点提出意见。

Variation,Genetics and Strategy on Selection Breeding of Pulp Wood of Masson Pine

This paper is a review of authors'research results on genetic improvement ofpulp wood of masson pine. At fist the breeding objectives for pulp production of masson pineare defined,then the genetic variation,genetics,genetic correlation and stability of woodyield,wood quality and paper/pulp-making properties are discussed systematically,the opti-mum provenance zones and seed sources for pulp wood through comprehensive evaluation onwood yield,wood quality and paper/pulp-making properties were determined,finally a lot offamilies and individuals with high growth rate and good wood quality were selected.The se-lection strategy and future research emphasis of pulp wood breeding of masson pine is alsodiscussed.
