药用植物全基因组选择育种研究策略及应用展望OA

Medicinal plants,as crucial resources for both modern medicine and traditional medical systems,hold strategic significance in enhancing medicinal component content and ensuring medicinal material quality through genetic improvement.However,the complex target traits of medicinal plants and the long breeding cycle and other issues restrict the efficiency of selecting and breeding superior germplasms of medicinal plants.Genomic selection(GS)breeding,a novel approach utilizing high-density genetic markers,aims to shorten generational intervals through early selection and improve the accuracy of breeding value estimation.This method effectively enhances the selection efficiency for target traits and reduces breeding cycles,offering an innovative pathway to overcome the bottleneck of coordinated improvement of complex traits in medicinal plants.This review systematically reviews GS breeding strategy and construction of the predictive model,and their current applications in medicinal plant.Furthermore,it provides a comprehensive summary of existing challenges and prospects of GS breeding of medicinal plants.The breakthrough in GS breeding of medicinal plants will drive the breeding of medicinal plants into a new stage of"intelligent design",providing scientific and technological support for the sustainable utilization of traditional Chinese medicine resources.
