对设在福建省大田桃源国有林场的15年生马尾松高产脂初级种子园子代测定林进行生长性状调查分析,结果表明,生长性状在家系间差异均达极显著水平。生长性状家系遗传力0.5 360～0.5 427,单株遗传力0.1 816～0.2 501。以单株立木材积遗传增益为指标选择出4个马尾松高产脂速生家系和8株优良单株,生长性状选择效果显著。
對設在福建省大田桃源國有林場的15年生馬尾鬆高產脂初級種子園子代測定林進行生長性狀調查分析,結果錶明,生長性狀在傢繫間差異均達極顯著水平。生長性狀傢繫遺傳力0.5 360～0.5 427,單株遺傳力0.1 816～0.2 501。以單株立木材積遺傳增益為指標選擇齣4箇馬尾鬆高產脂速生傢繫和8株優良單株,生長性狀選擇效果顯著。

Investigation and analysis based on 15 years old progeny test stand which was established on Taoyuan national forest farm, showed that there were significant growth differences among families. Family heritahility of growth was 0.5 360 to 0.5 427, and individual heritability was 0.1 816 to 0.2 501.4 families and 8 individuals were selected＇ according to volume genetic gain.
