摘 要:火炬松树干通直度遗传变异及选择效果初探@吕本树@姜景民@孙海菁¥中国林业科学研究院亚热带林业研究所火炬松,种源—家系,通直度,遗传变异火炬松树干通直度遗传变异及选择效果初探*吕本树姜景民孙海菁关键词火炬松种源—家系通直度遗传变异在火炬松(Pinustaed...The investigation on the stem straightness of loblolly pine on five 10yearold proven ances tests and one 6yearold halfsib progeny tests plantation of seed orchard revealed that,there were marked difference among provenances in each test with GCV=4.64%~15.25% and H2=0.49~0.83,but the variations among families were not significant.The relationship of straightness with most of the growth traits were not close,namely it was independantly inherited.When stem straightness was used in multitrait selection for building lumber or pulp wood,the straight,highyielding and high wood quality provenances or families could be selected.
