以试管式松脂收集法对城步县32年生马尾松子代测定林的80个家系进行调查分析。发现马尾松家系内产脂量差异显著，湖南省内马尾松家系明显高于湖南省外家系，湖南省内平均产脂量是湖南省外平均产脂量的2倍。生长性状中胸径与马尾松产脂量相关系数为0.440，枝下高为-0.002，在生长性状中胸径与产脂量相关系数最高，枝下高与产脂量相关性较小。本文根据产脂量选择优良家系，共选出20株湖南省外优树，16株湖南省内优树。

Through the investigation and analysis of 80 families of filial generation 32-year-old testing forests of Pinus massoniana in Chengbu County by tube type resin collection method.The resin yield of P.massoniana is significant difference,and resin yield in Hunan Provincewas significantly higher than it of other provinces,the average resin yield in Hunan Province is 2 times than it of the other provinces.The correlation coefficient between theresin yield with character DBH and height of the branch was 0.440 and -0.002 respectively.The highest correlation coefficient is DBH,and lowest is height of the branch.Based on resin producing capacities,20 superior individual of outside Hunan Province and 16 in-side were selected.
