摘　　要：对19年生红皮云杉(Picea koraiensis)半同胞子代测定林(简称9501区)的苗高生长量分析表明,红皮云杉家系间存在丰富变异。52个家系差异极显著,选择26个为优良家系,其中4个为最优良家系。对这4个最优家系内单株分析表明,单株变异较大;其中,M185高生长最大的单株是490cm,最小的单株是270cm,相差1.82倍;M180高生长最大的单株是470cm,最小的单株是240cm,相差1.96倍;M9112高生长最大的单株是421cm,最小的单株是250cm,相差1.68倍;N10高生长最大的单株是450cm,最小的单株是80cm,相差5.63倍,家系内单株差异极显著,是建立第二代种子园候选家系。The high growth of half-sib progeny test forest 19 years old Picea koraiensis was analyzed.Results showed that there was a rich variation among the families.The difference was significant among the 52 families.26 were superior families and 4 were best.Analysis showed that the variation was larger among the best families.The maximal high-growth of individual was 490 cm and the minimum was 270 cm in M185.The difference was 1.82 times.The maximum was 470 cm and the minimum was 240 cm in M180.The difference was 1.96 times.The maximum was(421cm) 1.68 times of the minimum(250cm) in M9112..The maximum(450cm) was 5.63 time of the minimum(80cm) in N10.The difference was significant between individual of families,which was the candidate family to establish the second-generation seed orchards.
