; Perdue, 1958 ). Since its introduction, giant reed has been widely cultivated in North America and has escaped cultivation in some areas ( Perdue, 1958 ). Genetic diversity is important for the selection, cultivation, and potential breeding of A. donax

from a restricted germplasm often limited their genetic diversity, as shown in most islands of the Mediterranean Sea. Thus, the Mediterranean area is considered as a secondary source of domestication for almond ( Felipe, 2000 ; Kester et al., 1991

adaptation to new ecological and manmade conditions. Thousands of landraces, old and modern cultivars, are cultivated and maintained in gene banks across the European continent. Genetic diversity of the collections has been evaluated in numerous studies using

distributed in southern China. However, there is limited information on the characterization of these germplasm resources. Xie (2004) collected three natural populations from Guangzhou in China and analyzed their genetic diversity by random amplified

Commission International Cooperation for Developed Countries, 2002 ; Krichen, 2001 ), to elaborate a national core collection and to preserve these genetic resources. Several works have been published on apricot morphological diversity ( Badenes et al

goals of this research were to apply genotyping-by-sequencing to discover SNPs for bigleaf hydrangea cultivars, investigate the genetic diversity and population structure of H. macrophylla cultivars, and determine the disputed taxonomic classification

exhaustive collection of local cultivars and landraces of Chinese sand pear has been assembled. Molecular techniques are useful tools for evaluating genetic diversity and for defining genetic relationships in fruit tree crops. In pear, chloroplast polymerase
