Genomic DNA Extraction and RAPD Primer Screening of Carya cathayensis
The methods of CTAB, rapid CTAB , SDS and low pH medium were used for genomic DNA isolation of Carya cathayensis. The results indicated that the method of SDS was the most suitable one for Carya cathayensis genomic DNA isolation. Twenty primers were screened from 600 kinds of 10 bp random primers, which could produce stable and polymorphic bands.
