Research Progress of Molecular Marker Technology Applied in Cotton Variety Identification Abstract£ºThere are three phases of DNA fingerprint technology based on molecular marker£ºthe first is RFLP based on Southern blot£¬the second are several markers based on PCR and the third is SNP£¨single nucleotide polymorphism £©.Research and application of variety identification technology was discussed£¬four main molecular marker technologies applied in cotton variety identification were introduced in detail as follow:RFLP,RAPD,AFLP and SSR.Technology principle,research and application status,advantage and disadvantage about each molecular marker applied in cotton variety identification were expatiated.As compared£¬the viewpoint was put forward:SSR marker was the most appropriate molecular marker in cotton variety identification,and the necessity of construction of Chinese cotton DNA fingerprint database based on SSR marker technology was analyzed.
