In the artificial - planting, the strain of cordyceps militaris is easy to degenerate. at present, the study about the fungus in cordyceps genus are just in the identification of fungi 、 the nutrition analysis 、 the using in medicine and artificial - planting. although, it could reduce the lost by the usual breeding way, we could not solve the problem at basic. about the degeneration of strain, people mostly use the gender - cycling 、 the fusing - cytoplasmic technology and the genetic - engineering method to reform the strain. most of people use moleculor method in the study of relationships among the species and between the species
用常規選育方法雖然能減少一定的損失，但不能從根本上解決菌種退化這一長期困擾企業生產的問題。針對菌種退化問題，主要是利用有性循環、原生質體融合和遺傳工程等途徑進行菌株改良，應用分子生物學手段只是研究種內、種間的系統關系等，而關于菌種退化遺傳機理的研究尚未見報道。菌種退化是菌類栽培過程中普遍存在的，也是生產當中迫切希望得到解決的問題。 -
