马尾松是我省最重要的造林树种,在工农业生产、生态环保等方面有着重要的作用。本研究根据已掌握的马尾松群体及个体的遗传变异规律,进行遗传测定,开展二层次选择,充分挖掘种内各层次变异,达到最佳增益水平,大大提高马尾松的经营水平。 Masson pine is the most important afforestation species in our province and plays an important role in industrial and agricultural production and ecological protection. In this study, based on the genetic variation of Masson massoniana population and individuals, the genetic determination was carried out. Two levels of selection were made to fully exploit the variation at each level within the species and reach the optimum gain level, which greatly improved the management level of Masson pine.
