A study on superior family selection and genetic gain of pinus massoniana
摘要
Abstract
This paper analyzes the growth traits and genetic gains of 33 selected families in the 8-year-old pinus massoniana progeny forest. The results show that tree height,diameter at breast height,and volume of No. 31 are 11. 74 cm,7. 87 m,and 0. 039 8 m3 respectively,which is significantly higher than those of other families. It further set a standard that superior families should be higher than the population by 5%in the tree height and diameter at breast height and 15% in volume. Therefore,No. 31 and No. 4 are se-lected. The heritability of DBH and tree volume are 0. 31 and 0. 30,with the latter getting the highest ge-netic gain of 0. 64.关键词
