disease ( Bryla et al., 2008 ). The level of resistance to P. cinnamomi is known to vary among cultivars, but most studies have focused on rabbiteye ( Vaccinium ashei Reade) or southern highbush blueberry ( V. corymbosum L. interspecific hybrids
organogenesis has only been established in a limited number of cultivars. Increasing evidence shows that protocols developed for regenerating blueberries are cultivar specific ( Debnath, 2005 , 2009 ; Liu et al., 2010 ; Meiners et al., 2007 ), implying that
Cultivated highbush blueberries are clones that were developed by crosses involving Vaccinium section Cyanococcus species. Section Cyanococcus includes northern and southern highbush cultivars (complex hybrids based on V. corymbosum and
, Europe, Asia, and Africa ( Ratnaparkhe, 2007 ). The three major commercially grown blueberry types are highbush ( Vaccinium corymbosum ), lowbush ( Vaccinium angustifolium ), and rabbiteye ( Vaccinium virgatum ) ( Ratnaparkhe, 2007 ). Highbush cultivars
cross-pollination between cultivars is widely acknowledged by commercial growers, there is little information available on cultivar compatibility for home gardeners. Thus, when a new blueberry cultivar becomes available to the retail sector, one of the
-rooted plants on amended soil during the first 2 years of production. Thus, the use of V. arboreum as a rootstock for grafted SHB cultivars has the potential to decrease the use of pine bark (or other soil amendments) needed for optimal blueberry production
As blueberry cultivar development advances, increasing numbers of new cultivars released for north-temperate areas contain some amount of southern-adapted germplasm, usually Vaccinium darrowii Camp (typically <12%) ( Brevis et al., 2008
as a result of global climate change and higher than average winter temperatures ( Gu et al., 2008 ). The chilling requirements of most blueberry cultivars are satisfied by midwinter. If temperatures warm prematurely after this point, flower buds can
