Summary:The aim of this study is to breed excellent larch timber as building material by evaluating the growth and stem form characteristics of larch species and their hybrids. This study was carried out in a 32-year-old larch experimental forest in Qingyuan County, Liaoning Province. The growth and stem form characteristics of 4 larch species (Larix kaempferi Carr, L. gmelinii Kuzen, L. olgensis Henry and L. principis-rupprechtii Mayr) and 4 hybrids (L. kaempferi Carr × L. gmelinii Kuzen, L. kaempferi Carr × L. principis-rupprechtii Mayr, L. kaempferi Carr × L. olgensis Henry, and L. kaempferi Carr × L. kaempferi Carr), were analyzed and the differences was evaluated comprehensively using the membership function based on Fuzzy mathematics. The results showed that the growth properties of larch species and hybrids had significantly differences (p<.01), there were no significant differences between the larch hybrids and their female parent in the increments of diameter of breast height (DBH), tree height, and volume,
