aerospace Siraitia grosvenorii C. Jeffrey;;early maturity mutant;;excellent characteristics;;application

The early maturity mutant of aerospace Siraitia grosvenorii C.Jeffrey was a special germplasm that is found for the first time in breeding.In order to further understand and utilizeits superior characteristics,the traits included growth stages,morphological characteristics,fruit quality and mating systems of different breeds of males and females amony aerospace S.grosvenorii,normal S.grosvenorii and natural S.grosvenorii were compared and analysed.The results showed that the female early maturity mutant of aerospace S.grosvenorii had excellent characteristics as follows,longer whole growth stages,bigger and heavier fruit,earlier maturity,higher content of mogroside V,and the optimal mating system of female early maturity× male aerospace S.grosvenorii.The two breeds of aerospace germplasm had brigt prospects for application and promotional value,and they could serve as the resources for a new direction of Siraitia grosvenorii planting and breeding in the future.
