Gansu Zhangye Network News (reporter Wu Kaiyi) Recently, the National Natural Science Foundation of China announced the results of the 2018 annual fund project review, and the "Genetic Evaluation Study of Excellent Single Plants of Free Pollinator Generation in Qinghai Spruce Seed Garden Based on Forward Selection" and "Research on the Spawning Behavior of Large Mole Wasps based on Host Volatile Substances" projects submitted by Zhang Hongbin and Lü Dong of the Qilian Mountain Water Conservation Forest Research Institute in Gansu Province were funded by the National Natural Science Foundation of China.
"Genetic Evaluation Of Excellent Single Plants of Free Pollination Offspring in Qinghai Spruce Seed Garden Based on Forward Selection", based on the free pollinator generation of qinghai spruce seed garden of Qinghai spruce in Qilian Mountain, on the basis of developing the specific SSR molecular markers of Qinghai spruce, reconstructed the whole sibling family lineage between the clone lines of the first generation of spruce seed gardens and the screening of subgenus excellent trees, estimated the breeding values of the first generation of asexual lines in the seed garden, and constructed a regression model between the SSR marker and the breeding values of the target traits of Qinghai spruce. Genetic evaluation of the genetic gain of qinghai spruce 2nd generation breeding parents and the construction of 2nd generation seed gardens. The project "Research on the Spawning Behavior of Cypress Mole Wasps Based on Host Volatile Substances" comprehensively uses biological, behavioral and chemical ecology methods to collect plant volatile substances by dynamic headspace collection method, and uses compound analysis technologies such as GC-MS, GC-EAD, antenna potential, wind tunnel and "Y" olfactory and other compounds to conduct indoor electrophysiological experiments and behavioral experiments to study the characteristics of host volatile substances and the egg laying behavior of Cypress mole wasps, and to clarify the information transmission substances of the biological behavior of wasps in Cypress moles It reveals the relationship between the spawning behavior of the large beetle of the cypress mole and the volatile substances of the host, clarifies the chemical communication mechanism between the spawning of the beetle of the large wasp of the cypress mole and the selection of the host cones, and provides a reliable theoretical basis and scientific and technological support for the co-evolution of the wasps and the ecological regulation, population monitoring and chemical control of the bees of the large moles of the cypress.
As the main channel for supporting the field of applied basic research in China, the national natural science foundation of China has received funding from the National Natural Science Foundation of China, which shows that the efforts made by the institute in the field of basic research in the field of forest genetic breeding and the construction of forest tree seed bases have achieved results, and is expected to further promote the improvement of scientific research business and service capabilities.
