对14 a生不同种源家系红皮云杉营建的子代测定林的树高和胸径进行调查，并对其进行方差分析和多重比较，结果表明：不同家系间的树高和胸径生长存在显著差异，树高生长表现最好的家系为M185（361．33 cm），超过群体平均值（290．17 cm）24．52％，超过最差家系M016（239．78 cm）50．69％，超过对照3（298．80 cm）20．93％；胸径生长表现最好的家系为M180（4．12 cm），超过群体平均值（3．23 cm）27．55％，超过最差家系M176（2．34 cm）76.07％，超过对照3（3．41 cm）20．82％。综合树高、胸径2个生长性状，选择M185、M180、N10、M9112、M136、N02为优良家系，其树高和胸径的遗传力分别为0．62和0．63，遗传增益分别为13．36％和19．46％。
對14 a生不同種源傢繫紅皮雲杉營建的子代測定林的樹高和胸徑進行調查，併對其進行方差分析和多重比較，結果錶明：不同傢繫間的樹高和胸徑生長存在顯著差異，樹高生長錶現最好的傢繫為M185（361．33 cm），超過群體平均值（290．17 cm）24．52％，超過最差傢繫M016（239．78 cm）50．69％，超過對照3（298．80 cm）20．93％；胸徑生長錶現最好的傢繫為M180（4．12 cm），超過群體平均值（3．23 cm）27．55％，超過最差傢繫M176（2．34 cm）76.07％，超過對照3（3．41 cm）20．82％。綜閤樹高、胸徑2箇生長性狀，選擇M185、M180、N10、M9112、M136、N02為優良傢繫，其樹高和胸徑的遺傳力分彆為0．62和0．63，遺傳增益分彆為13．36％和19．46％。

The height and diameter at breast height ( DBH) of 14 yeas old progeny test forest of Picea koraiensis Nakai with different provenance and families were conducted an investigation , the results of ANOVA and multiple comparisons indica-ted that significant differences of height and DBH existed among different families , the best expression of tree height was M185 (361.33 cm), which was 24.52%over than population average value (290.17 cm), exceed the worst family M016 by 20.93%(239.78 cm),and was 50.69% more than control 3 (298.80 cm); the best expression of DBH was M180 (4.12 cm), which was 27.55% over than population average value (3.23 cm), exceed the worst family M176 by 76.07%(2.34 cm), and was 20.82% more than control 3 (3.41 cm).Basis on the two growth characters, M185, M180, N10, M9112, M136 and N02 were chosen as superior families , the heritability of height and DBH was 0.62 and 0.63, respectively;genetic gain was 13.36%and 19.46%.
