The invention discloses a castanopsis hystrix wood material color breeding method. The method comprises the following steps: 1) identifying and screening metabolic components of heartwood and sapwood to obtain differential metabolic components; 2) measuring the total content of different metabolic components of the heartwood and the sapwood of the castanopsis hystrix to obtain the total content of the metabolic components of the heartwood and the sapwood; (3) carrying out multi-site genetic variation and genetic parameter estimation on the total content of the metabolic components in the step (2), and screening to obtain characters which have obvious interaction with sites and belong to high genetic control; and (4) performing genotype and environment interaction influence analysis on the characters screened in the step (3), screening out a family with the characters adapting to the environment and stable inheritance, and continuously breeding the family to obtain the castanopsis hystrix meeting the requireme
