Prof. Liu Qinghua mainly engaged in the genetic improvement of timber, resin production and Bursaphelenchus xylophilus resistance of Pinus massoniana. 32 excellent strains of Pinus massoniana resistant to Bursaphelenchus xylophilus were screened out, 1 new variety was authorized, and technical support for resistant seeds in Zhejiang, Jiangxi and other places. The construction of the garden lays a material foundation for solving the problem of Bursaphelenchus xylophilus through resistance breeding. Significant progress has been made in the mechanism of Pinus massoniana resistance to Bursaphelenchus xylophilus, revealing that five terpene genes play an important role in the defense against pine wood nematode. Dry dose, the immune effect reaches 99%. Published more than 30 papers as the first author or corresponding author. As the main backbone, it approved 3 fine varieties of Masson pine, authorized 1 new variety, participated in the formulation of 3 standards, and won 1 second prize of Liangxi Forestry Science and Technology Award.
