摘要
在广东省19个马尾松主产区,选出508株优良马尾松单株。经过苗期筛选,对263个入选家系进行了10年生半同胞子代林测定,选择出59个马尾松优良家系。与对照高州优良商品种源比较,第Ⅰ批子代测定入选的优良家系平均树高>3.6%,平均胸径>8.8%,平均材积>23.5%,第Ⅱ批子代测定入选的优良家系平均树高>17.9%,平均胸径>24.3%,平均材积>81.3%。
By multi-places, multi-repetition selection test of 508 Pinus massoniana superior trees from 18 regions of Guangdong Province, 59 superior families were selected, The one batch, compare with controls, increase of heights was up to 3.6% ,basal diameter was up to 8.8% ,volumes was up to 23.5%, by Pinus masoniana superior families. The second batch increase of heights was up to 17.9% ,basal diameter was up to 24.3% ,volumes was up to 81.3%.
