马尾松种子园营建初报

于宜昌市林科所营建马尾松种子园20hm~2。其中无性系园(马尾松一代重建嫁接种子园)13.333 hm~2,共收集154个经过子代鉴定、遗传增益大于10%的优良无性系;实生苗种子园6.667 hm~2,于枝城市、远安县、咸丰县等马尾松优良种源区选择优树145株,选用了120个优树家系苗。建园中采用了圃地小砧嫩枝诱根嫁接、一次性定植、计算机软件(SODP)优化排列设计等先进技术。

Preliminary Report on the Seed Orchard's Construction of Masso(?) Pine

Afer collecting 154 superior clones (which have been through the progeny test and have more than 10% genetic gain), selecting 145 plus trees in the provenances of superior masson pine such as Zhicheng (city), Yuanan and Xianfeng (counties) and further pickiog out 120 plus tree families among the 145, we constructed a masson pine's seed orchard in our Yichang city's forestry scientific institute with total area of 20 hm~2, among which 13. 333 hm~2 is clonal seed orchard (are—established F_1 seed orchard by grafting), the other 6. 667 hm~2 is the seedling seed orchard.
