摘 要: | 通过对漳平五一林场4年生159个家系马尾松种子园自由授粉子代测定林的生长调查研究,来判定亲本的优劣,估算遗传力等主要参数,计算出选择后的遗传增益,结果表明:用家系内优良单株的子代造林,其增益是家系间和家系内选择增益之和,3年生时树高增益为21 2%,可显著提高马尾松用材林产量,说明进行家系选择是提高林木产量的重要途径。

The Open Pollination Progeny Tests of Pinus massoniana Seed Ochards |
| |
Abstract: | The results show that the gain with planting with fine individual tree progeny within family is the sum of selective gain among families and selective gain within family,the tree height gain is 212% at the age of 3,Pinus massoniana timber stand yield may be raised remarkably,which shows that conducting family selection is an important way of raising the forest tree yield. |
