  • It was found that there are rich family genetic variation in growth and branch traits of Masson Pine, and it is possible to acquire moderate genetic gain through selection. Tree height, basal diameter, crown, branch length and angle are under moderate and strong genetic controlls, while branch number and thickness are under weak and moderate genetic controlls. The significant genotype × environment interaction was found for tree height and base diameter. 40 better families could be selected using method of breeding value evaluation.

Abstract: It was found that there are rich family genetic variation in growth and branch traits of Masson Pine, and it is possible to acquire moderate genetic gain through selection. Tree height, basal diameter, crown, branch length and angle are under moderate and strong genetic controlls, while branch number and thickness are under weak and moderate genetic controlls. The significant genotype × environment interaction was found for tree height and base diameter. 40 better families could be selected using method of breeding value evaluation.
