Research Progress on Genetic Breeding of Stropharia rugosoannulata
As a recommended edible mushroom for cultivating in developing countries by the Food and Agriculture Organization of the United Nations,Stropharia rugosoannulata(the roundhead mushroom)is rich in nutrients and easy to cultivate.In recent years,S.rugosoannulata industry in China has been developing rapidly,leading to an urgent demand for excellent varieties.Meanwhile,the breeding research of S.rugosoannulata in China has also achieved some positive results,but there is a lack of systematic collection and report at present.This study reviewed the research progress on genetic breeding of S.rugosoannulata for the first time,including genetic characteristics,distribution of germplasm resources,breeding methods and achievements,excellent varieties that have been officially certificated or patented,and prospected for the key direction of S.rugosoannulata breeding,in order to provide reference for the breeding of excellent varieties of S.rugosoannulata and the selection of suitable varieties when introducing this mushroom to different regions in China.
