Vaccinium arboreum (sparkleberry; section Batodendron ) is a widespread and abundant diploid blueberry species native in the southeastern United States ( Stockton, 1976 ; Vander Kloet, 1988 ). It flowers in April in north Florida and produces

Worldwide production of highbush blueberry ( Vaccinium sp.) has increased tremendously in recent years, from ≈42,000 ha in 2005 to over 109,000 ha in 2014 ( Brazelton, 2016 ). This rapid growth is driven by strong consumer demand for the fruit and

Morphological characteristics of many derivatives from Vaccinium arboreum Marsh × Vaccinium section Cyanococcus crosses were studied. The purpose of the study was to determine if V. arboreum traits were being inherited and expressed in hybrid progeny and to identify characteristics that would enable hybrid field identification. This study focused on the F1 hybrids of V. darrowi Camp × V. arboreum (F1 hybrids) and the open-pollinated progeny of the F1 hybrids [mother is known (MIK)]. Also included in the study were the parents: V. darrowi, V. arboreum, and V. corymbosum L. (pollen parent of the MIKs). Many leaf, flower, and fruit characteristics were measured for all five taxa. Leaf characteristics included length, width, and presence or absence of stalked glands, pubescence, and marginal bump glands. The floral characteristics measured were corolla length and width, corolla aperture, pedicel length, peduncle length, bracteole length and width, and the presence or absence of anther awns and bracteoles. Berry and seed mass were the fruit characteristics investigated. Four unique V. arboreum traits were found to be expressed in the F1 and MIK hybrid populations. These were the presence of anther awns, large seed size, bracteole shape, and marginal glands. These traits should permit field identification of hybrid plants.
