摘要： <正>以平均单株有效产种量（Ｅ）和种子园自由授粉子代家系３年生平均树高（Ｈ）为评判因素，采用模糊综合评判方法，对马尾松种子园８７个无性进行了评价，入选率为６０％时，改建或重建无性系种子园的平均单株有效产种量可增加２９．１７％，其自由授粉子代的３年生平均树高提高３．１１％

Abstract: Using the average effective seed yield of per tree and the 3－year－old mean height of open－pollinated families in seed orchard as judging factors ,87 clones in masson pine seed orchard were evaluated by means of fuzzy comprehensive judgement. When the ratio of being selected is 60%,comparied with the current seed orchard, the gain of the 3－year－old average height of families in 1.5 generation seed orchard could be 27.17% and 3.11% respectively.
