Study on the Genotypic Stability and Grown Adaptability of Paulownia Clones

Genotypic stability and grown adaptability of 11 clones of Paulcwnia that were six years old at five site were analysed using both of Eberhart-Russell model and Tai's structural model. Variance analysis indicated that the clone effect, site effect and clone x site interaction effect are great significant. Grown adaptability and genotypic stability indexes of paulownia clones were estimated using the regression coefficient (b) and deviation from regression mean square (Sd2) of E & R model, the structural analysis parameters â and λ of Tai's model. The results for analysis of stability and adaptability from two ways are similar.Clones were evaluated based on the genotypic stability and grown adaptability.
