This study was conducted to investigate growth performance and provenance by site interaction in Pinus strobus (Eastern White Pine) provenance tests for selecting superior provenances in Korea. P. strobus was planted in 1972 at four test sites in Korea and the growth was analyzed at age 39. The growth of P. strobus was positively correlated with relative humidity and precipitation and negatively correlated with temperature of the test sites. The portion of interaction term of the total variation explained 2.5% in height and 24.6% in diameter of the total variation according to the regression analysis. The method of combined stability and performance index (CSPi) ranked the North Carolina provenance as the best provenance with good adaptability.
