摘　　要：于１９８５～１９９５年在河南省卢氏县油松种子园连续观测了３１个无性系的雌雄球花产量，结果表明，雌、雄球花量无性系间差异达极显著水平，两者无性系重复力在分析的６ａ中分别高于６５．１２％和８６．４９％。无性系雌、雄球花量与年度的互作效应亦达到极显著水平，其方差分量分别为１２．０３％和３７．９４％。由于雌、雄球花量存在大小年现象，无性系选择尚须在稳定性筛选的基础上进行。不同无性系雌、雄球花量年份稳定性差异大，所分析的３１个无性系中，雌、雄球花量稳定的无性系各有２０和２２个，因此，选择花量大且稳定的无性系建园是可能的。此外，还就雌。The successive observations on the female and male strobilus production in Pinus tabulaeformis Carr.seed orchard,located in Lushi County,Henan Province,were carried out during 1985～1995. There was a fluctuation in female and male strobilus production with about a 4 year cycle,and the fluctuations of cone with filled seeds among the years coincided with the male strobilus production,the variations of the cones with filled and emptied seeds did not tend to be stable until abundant cone production.There were significant differences for strobilus production between clones,clonal repeatability of female and male strobilus production over the years were all over 65.12% and 86.49% respectively,greater differences for strobilus production in a seed year than alean year,and in abundant cone period than initial period,and smaller differences between rametswithin clone.The interactive effects of different clone and year for female and male strobilus production were significant,and variance components of interactive effects for female and male strobilus production were 12.03 % and 37.94% respectively.20 clones of stable production for female strobilus and 22 for male were selected from 31 clones.
