Abstract: Planting tests of 9 secondary provenances of Robinia pseudoacacia have been conducted in Yuanyan County, Henan Province, Ci County, Hebei Province and Dengkou Experimental Bureau CAF for 8 years. The results show that there are genetic differences among the 9 secondary provenances. Data of Xijk, are used to conduct a linear model analysis and a comparison of i, and is made to analyze G×E and evaluate the productivity. Provenance adaptability is evaluated by means of XPB2 and CVPB. Volume gains of the selected superior secondary provenances in Central plains, North China and Hetao Area are over 13.0%, 11.7% and 18.5% respectively.
