Study on the Interaction of Genotype-Environment of the Block Locust’s Clones——Evaluation of the Genetic Stability and Growth Adaptability

The 8 year's data of 48 clones of Robinia pseudoacacia selected preliminarily from the poly-site experimental stands have been summarized and the interaction between genotype and environment has been made for the 13 clones from 6 experimental sites.Their genetic stability and growth adaptability have been evaluated using Eberhart ect's bi and Sd2 of the trait regressive parameters and Tai's i and i,of the structural model parameters,and the superior clones have been selected after the consideration of their productivity.A number of 10 superior clones have been selected for different regions and the average gain for the volume is 61%.
