Collection of Gossypium spp.Germplasm of Uzbekistan

Objective]The purpose of this paper aimed to provide the cotton Gossypium spp.germplasm collection and research experiences of Uzbekistan for the researchers in China.Method]This article reviewed and summarized Uzbekistan scientists'experience in the collection and studying of cotton gennplasm which were covered in six parts:content,storage,utilization,sharing and exchange,location,maintenance and funding,and their current efforts on characterization of the collection.Result]There are the main cotton germplasm collections preserved in America,France,China,India,Russia,Uzbekistan,Brazil,and Australia,which can represent the majority of worlds cotton gennplasm resources.Uzbekistan has one of the largest and richest cotton gennplasm collections in the world,covering most of the species for the Gossypium genus.Cotton accessions and species encompass wide geographic and ecological niches and represent large amplitude of morphobiological and genetic diversity.Basic infonnation of die eight largest gennplasm centers were showed in the attached table in this paper,such as the cultivated tetraploid species number,the wild primary,secondary and tertiary cotton species,and diversity on flower color and on leaf plate shape of G. hirsutum germplasm.Conclusion]There are many experienced staffs,much cotton germplasm,and much workout in this field in Uzbekistan.
