The Multi-enviroment Trail of Chinese Fir Growth Traits and the Early Stage Selections for Superior Families with Leanness-resistant to Poor Soil

Twelve Chinese fir families were used for multi-envrioments trials in Jiangle state-owned forest, Guanzhuang State-owned Forest and Yangkou State-owned Forest in Fujian Province, and genetic parameters were estimated for their 5-year growth traits using a mixed linear model to screen Chinese fir families for barrenness tolerance.The results showed that Chinese fir did not show significant gene-environment interactions in the early stage;the general cooperativeness of the families were used as a criterion for fir family selection, among which, family 11, 10, 2, and 4 in Yangkou State-owned Forest, family 3 and 8 in Jiangle State-owned Forest and family 3, 7, 9, and 5 in Guanzhuang State-owned Forest, could be used as materials for selection of new barren-tolerant varieties of Chinese fir.
