Two special bands,with the molecular size of 740 bp and 649 bp between Actinidia deliciosa cv.Hayward and Wancui were separated,purified,cloned and sequenced.Two couple of special primers in 20 bp were designed and synthesized for SCAR-PCR.The result of the SCAR-PCR amplification showed that one of the special bands,the molecular size was 649 bp,did not exist actually.There was a piece of special band with the molecular size of 740 bp in the SCAR-PCR of Wancui,but not in that of Hayward.Therefore the specia...
