摘要
苗期试验结果表明 ,不同来源的油松家系后代生长差异不明显 ,同一来源的不同家系后代苗木生长量差异很大 ,生长最好的家系后代比生长最差的高生长大一倍以上 ,家系选择增益显著。油松种子园种子遗传品质较好 ,其苗木高生长比商品种子培育的苗木大 18.3%。
The results of seedling trial indicated that there are no evident growth difference among Pinus tabulaeformis family progenies which come from different place, but highty significant difference is existed in that come from the same place.As the results, the height growth of the best family progeny is one time more than the worst one, and the family selected gains is significant. The genefic quality of seeds from seed orchard is better,and its seedling height is 18.3% more than that of commericial check lot.
