Peach ( Prunus persica L.) is native to China and has been cultivated in China for the past 4000 to 5000 years ( Ahmad et al., 2011 ; Maynard, 2008 ; Thacker, 1985 ). The homogeneity of peach recently resulted in the erosion of genetic diversity

RFLP probes were developed to determine the degree of genetic diversity both within and between 12 walnut species (Juglans spp.), including the widely cultivated English walnut (J. regia). One to three kilobase DNA fragments from Pst I digested J. regia nuclear DNA were cloned using the vector pUC18. Inserts corresponding to low copy number walnut genomic sequences were used to assess the genetic variability among walnut species. Extensive polymorphism was found between species and limited polymorphism within species. The inheritances of the RFLP loci are being analyzed to provide a genetic basis for the polymorphisms detected and to establish a RFLP based linkage map in walnuts
