hybrids have been reported ( Burbank, 1914 ; Felipe, 2009 ; Shoferistov, 1988 ). Some hybrids have been widely used in fruit production either as scion cultivars or rootstocks. A hybrid rootstock for peach was derived from a cross of P. tomentosa and

breeding or segregating populations would be advantageous for identifying loci for use in marker-assisted selection. This improvement would be particularly useful in cold-hardy or hybrid grape breeding programs, which often use non- vinifera grape species

‘Nemaguard’ being favored by growers because of resistance to root knot nematodes ( Meloidogyne incognita and M. javanica ). In cases in which more scion vigor is desirable, peach × almond (PEAL) hybrids are being used, predominantly in newer almond
