In the paper, Criteria and method of selecting elite trees of Casta nopsis fissa and progeny test were studied on. The results showed that:(1) Absolute value was suitable for selecting elite trees of Casta nopsis fissa primarily. Using tree growth increment、 fiber length、 ratio of fiber length to width、 ratio of fiber cell wall to cavity combined to select elite trees could improve the effect of selecting. (2)Correlation analysis showed that breast diameter and height increment per year had no significant r...
