Review on the Status and Sustainable Utilization of Local Maize Germplasm Resources in Longnan
摘要
Abstract
As a key distribution area of local maize germplasm resources in Gansu Province,Longnan has preserved local maize varieties with unique genetic diversity.However,over the past 10 years,some varieties have undergone genetic drift or have been lost,and local maize varieties are now facing a severe conservation crisis.To ensure the high-quality development of the maize industry in Gansu Province and the sustainable development of dryland agriculture in Northwest China,targeted research on the conservation of Longnan local maize germplasm resources is imperative.This paper reviews the distribution and characteristics of Longnan local maize varieties,the evolution of planting layout in commercial maize varieties,the current status of local variety cultivation,and the preservation and utilization of local maize germplasm in Longnan.Suggestions are proposed for establishing a multi-level conservation system,developing regionally adaptive germplasm,optimizing traditional preservation systems in Longnan,and innovating germplasm resource sharing mechanisms to promote the conservation and sustainable utilization of local maize germplasm resources in Longnan.关键词
