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
Chinese cabbage, making it a popular dish that can be served throughout the year. Currently, most commercial cultivars of Chinese cabbage are hybrids. During the production of Chinese cabbage hybrid seeds, low temperatures, continuous overcast conditions
indicated that BC and PC are genetically nearer, whereas T302 is genetically closer to BC. Yu et al. (2009) completed the identification of Taxodium hybrids by sequence-related amplified polymorphism (SRAP) analysis. In this study, the authenticity of 4
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
, 1994 ). The utility of cpDNA to examine maternal lineages of hybrids has been documented in Hippophae goniocarpa ( Wang et al., 2008 ). ITS sequences are biparentally inherited in most angiosperms ( Álvarez and Wendel, 2003 ; Baldwin, 1992 ). Because
hybrid production. This process can be shortened by the generation of inbred lines from doubled haploid (DH) plants. Because the complete genome of DH plants is in a homozygous state, no heterozygous genomic regions are found, and completely homozygous
Orchid hybridization is a common and essential practice among orchid growers, and it is estimated that over 100,000 commercial hybrids have been developed worldwide at of the date of this writing aiming at the cut flower and flowering potted plant
