采收优树种自由授粉种子进行单亲本子代测验,在优树选定后可立即开始。此法简单易行,可对数量较多的优树作初步筛选,为以后的双亲本测验减少工作量,又可为改良代种子园提供一般配合力较高的材料。苗期测验的目的,是根据各子代家系苗期所表现出来的遗传变异规律,对优树选择效果作一初步评估,并尽早为合理地制定我省马尾松选择育种程序和策略提供信息。 Harvest tree species of free pollinated seeds for single parent offspring test, the tree can be selected immediately after the start. This method is simple and easy, which can make preliminary screening for a large number of superior trees, reduce the workload for future parents test, and provide materials with higher general combining ability for improved seed orchard. The purpose of the seedling test is to make a preliminary assessment on the effect of tree selection based on the genetic variation shown by each progeny family at seedling stage and provide information as early as possible for reasonably making the selection breeding program and strategy for masson pine in our province.
