Abstract
Adaptation to upland soils was investigated in a diallel study involving progeny of 4 blueberry (Vactinium) clones consisting of 1 highbush blueberry (V. corymbosum L.) clone and 3 interspecific hybrids. Both general and specific combining ability were significant. Seedling progenies of NJUS 11 (V. ashei × V. atrococcum) and US75 (V. darrowi × V. corymbosum) grew well on an upland soil. Although not included in the diallel crosses, NJUS 64 (V. myrsinites × V. angustifolium) progenies also grew well on upland soil.
( Sparks, 2005 ). Upland soils of the southeastern U.S. Coastal Plain, by contrast, are highly acidic, have relatively low cation exchange capacity, and are naturally low in various macronutrients and micronutrients required for pecan growth and production
greenhouse screening procedures have mainly been used to identify blueberry individuals or populations more tolerant to upland soils ( Korcak, 1986 ; Korcak et al., 1982 ) or higher pH ( Finn et al., 1987 , 1993a , 1993b ). These procedures might be useful
development interval. V. ashei is vigorous, high-yielding, adaptable to upland soils, and many cultivars have a tendency toward “suckering” (spreading by underground shoots). Its fruit are relatively large, as are the seeds, and it can be excessively seedy
