Abstract:
Based on the overview of the global distribution and taxonomic status of Fragaria and the evolution history about cultivated strawberries Fragaria × ananassa Duch. ex Lamarck, a detailed review on the advances in research, exploitation and utilization of Fragaria spp. germplasm resources in China was made.The research to strawberries germplasm resources includes investigation on the geographical distribution of wild resources and collection of Fragaria spp. germplasm resources,identification on the genetic relationships by molecular markers,karyotype analysis (F. pentaphylla Lozinsk,F. vesca L,F. gracilis A. Los,F. nilgerrensis Schlecht,F. viridis Duch,F. mandschurica Staudt and F. moupinensis(Franch)Card.) and estimation of genomic sizes (F. pentaphylla Lozinsk(red and white two types),F. nilgerrensis Schlecht.,F. moupinensis(Franch)Card.,F. mandschurica Staudt,F. vesca L. and F. viridis Duch.) of some species, mining functional genes and studying the genetic transformation, physiology and biochemistry (photosynthetic characteristics, active components and abiotic stress) about strawberries germplasm resources.The exploitation and utilization of Fragaria spp. germplasm resources include breeding new cultivars,introduction and domestication of wild resources.Breeding methods such as seedling breeding, hybridization breeding,mutation breeding and biotechnological breeding have been applied,and the most important one is hybridization breeding.Meanwhile, researches by foreign scholars were compared,the existing problems were then put forward.
