Current situation of breeding and germplasm resources utilization of qingyuan wapiti in fushun area and suggestions on countermeasures
Qingyuan wapiti is the first new breed of wapiti artificially cultivated in the world.It has the characteristics of stable heredity,high reproductive survival rate,high antler yield with good quality.Qingyuan wapiti had brought huge profits to farmers in Fushun and in China,which made up for the blank of wapiti breeding industry at home and abroad.Based on investigation,we have learned the current situation of breeding and germplasm resources,and found out the population size,structure and semen preservation in Fushun area,and analyzed the constraints affecting the development of the Qingyuan wapiti industry.From 2003 to 2023,the population size of Qingyuan wapiti in Fushun area continued to decrease.This indicates that the population size is in a state of extreme contraction.Due to the impact of imported deer species,the decline in propagation ability,the low level of breed-ing management,the weak ability of scientific and technological support,and the unclear orientation of industrial development,the number of germplasm resources of Qingyuan wapiti has been deteriorating and is on the verge of extinction.In this study,it is be-lieved that accelerating the research of policies for the protection,development,and utilization of Qingyuan wapiti provenance,strengthening the research and promotion of breeding,artificial insemination and genetic preservation technologies,deeply explo-ring the species value and the potential resource value of Qingyuan wapiti,and extending the industrial chain are the necessary to delay the sharp decline.It is also the basis for the growth and industrial development of Qingyuan wapiti population.
