Rabbiteye ( Vaccinium ashei Reade) blueberry production has steadily grown from less than 300 commercial acres in 1976 to ≈15,000 commercial acres in 2006 in the southeast United States (Texas, Louisiana, Mississippi, Alabama, Georgia, and

addition, 15 southern highbush accessions ( 2n = 4x = 48) from different blueberry breeding programs and two interspecific hybrids, ( V. corymbosum cv. Rubel × V. pallidum accession B0100) and ( V. elliottii accession B0230 × V. pallidum accession

a thumbnail, and contacting the pollen-loaded thumbnail to the stigma of the receiving flower. Hands were washed between pollinations. This methodology is routinely used within the University of Florida blueberry breeding program. For self

. Crosses resulted in group of “southern highbush” blueberries, which have shorter chilling requirements. This breeding innovation has allowed for the production of blueberries in the warm climates of North Carolina, Georgia, Florida, southern California

Southern highbush blueberries (interspecific hybrids containing mostly Vaccinium corymbosum L.) have gained a significant share of the production acreage of commercial blueberries in Georgia in recent years. A major reason for the interest in the

When blueberries were first selected from the forests of New Jersey and cultivated in the early 1900s, the traditional culture of this native smallfruit was essentially organic in nature. Commercial examples of organic horticulture being used

isolated, genetic engineering and transformation of blueberry will be a powerful approach to complement traditional breeding by rapidly introducing individual traits without changing the inherent desirable characteristics of existing cultivars ( Ratnaparkhe

their small seedling size and relatively slow growth rate. Finn et al. (1991) reported that in vitro screening in concert with a traditional breeding program could be effective for improving blueberry tolerance to higher pH. The objectives of the

). Accelerating the evaluation process and increasing the accuracy of selection are necessary for introgression of disease resistance genes into widely adapted blueberry cultivars. Breeding for disease resistance relies on finding sources of resistance within

Hancock, 2000 ; Krebs and Hancock, 1991 ). Diploid V. darrowii has been extensively used in breeding blueberries, but most crosses have involved only one V. darrowii clone, Fla. 4B. Vaccinium darrowii in Florida is quite variable. Lyrene (1986
