This study was carried out to examine the proper site for Pinus rigida ${\times}$ P. taeda. The 91 sample plots ($20{\times}10m$) were selected from the plantations located in middle part of Korea. Soil, environmental and climatic factors were investigated and regressed on the growth of Pinus rigida ${\times}$ taeda. (1) The factors which influenced strongly on the growth were temperature, elevation, soil moisture, physiographic position, slope, soil depth, wind protection, soil compactness and soil organic matter contents in order. (2) The most effective factors among them were temperature, elevation, soil moisture and physiographic position. (3) General conditions of proper site for planting the hybrid pine were above $-8^{\circ}C$ in mean minimum temperature in January, below 200m in elevation, moderate soil moisture, and valley or flat area in physiographic position.
