摘要
对水曲柳优树3 年生子代测定的数据进行方差分析、LSD、LSR 检验及相关分析的结果表明, 各无性系之间差异显著。苗高的重复率为0-67 , 地径的重复率为0-64 。子代与母树性状之间相关紧密, 其相关系数为0-77 ~0-88 。有培养前途的无性系为48 号, 其次为39 号和42号, 需进一步观察的无性系为17 号和43 号。
A variance analysis on the data of progeny test for 3 - year Fraxinus m andshurica Rupr . was made . The results of LSD, LSRtest and correlative analysisshow that there are sig nificance variationsin each clone , the repeatability ofseedling heightis 0-67 , the repeatability of ground diameter is 0-64 and the correlative coefficient between progeny and reserve - seed tree is closely , w hich is anout 0-77 ~0-88 . The best oneis clone 48 , the others are clone 39 and clone 42 , clone 17 and clone 43 need observating furtherly .
