Prof. Ding Junchang has been engaged in theoretical and technical research on genetic breeding and efficient cultivation of forests for a long time. As an important profession, he participated in the creation of ecological breeding theory for poplar, efficient breeding of varieties in different ecological zones, molecular breeding technology system for stress resistance. He analyzed the formation and maintenance mechanism of poplar heterosis systematically, explored genes with important value, mark metabolites and microorganisms, those provided scientific basis for in-depth understanding of Heterosis and precision hybrid breeding. Developed three forest biological information analysis platforms were, and filled the gap at home and abroad. He invented key technologies such as nutrient regulation of black poplar flower branches and raising survival rate of hybrid offspring seedlings, those significantly improved the quality of artificial hybrid breeding of poplars. He analyzed the formation and regulation mechanism in drought and salt tolerance, wood quality, photoperiod response of poplar, these provided the basis for the cultivation of breakthrough forest varieties.
23 new varieties with high yield, quality, and efficiency, and stress resistance had been breeding in the six major poplar production areas in China, covering more than 60% of the main poplar planting area and the application has reached 3 million mu, these upgraded the varieties and industrial in the main poplar planting area.
The genetic and phenotypic core collection bank of Populus deltoides were constructed, 150 high-quality, 43 high-yield and high-efficiency germplasms were created and excavated, respectively, as well as the evaluation system used photoperiod sensitive index Populus deltoides was established, which provided support for cultivation of efficient utilization varieties for forest resources. Revealed the regulatory mechanisms of stand density, tree structure, and site factors on the formation of yield and quality traits of poplars, and developed precise and efficient cultivation techniques for poplar plantations.
