‘Bluechip’ is a cane canker-resistant midseason cultivar of highbush blueberry (Vaccinium corymbosum L.). It has very large fruit, excellent color, stem scar, firmness, and a pleasant acid flavor. The name is intended to suggest that this cultivar possesses exceptionally desirable fruit flavor and texture. Released cooperatively by the North Carolina Agricultural Research Service and the U.S. Department of Agriculture, ‘Blue-chip’ is intended principally for fresh fruit production in areas subject to cane canker caused by Botryosphaeria corticis (Demaree & Wilcox) Arx & Muller.
‘Bounty’ is a stem blight-tolerant and cane canker-resistant early-midseason to midseason cultivar of highbush blueberry (Vaccinium corymbosum L.) ripening at about the same time as ‘Murphy’. It has been a consistent producer of very large fruit, with above-average flavor and excellent color, stem scar, and firmness. ‘Bounty’ flavor does not deteriorate rapidly, as is typical with standard highbush blueberries in eastern North Carolina. The name reflects the abundant crops of very large high-quality fruit produced by this cultivar. Released cooperatively by the North Carolina Agricultural Research Service and the USDA. ‘Bounty’ is intended for fancy fresh fruit production in areas subject to cane canker [Botryosphaeria corticis (Demaree & Wilcox) Arx and Muller] and stem blight [Botryosphaeria dothidea (Mouq. ex Fr.) Ces. & de Not.].
Vaccinium species collected from the eastern United States were grown and fruited at Castle Hayne, N.C. Harvest season extended from 5 June to 22 Aug. Vaccinium angustifolium Ait. was earliest ripening. Vaccinium myrtilloides Michx., V. elliotti Chap., diploid V. corymbosum L., and tetraploid V. pallidum Ait. populations also contained very early- to early-ripening seedlings. Early-ripening seedlings were not observed in tetraploid V. corymbosum populations and reached peak ripeness around mid-June, about with ‘Bluecrop’. One tetraploid V. corymbosum population continued ripening into early August. Vaccinium ashei Reade populations from Georgia began ripening about 2 weeks earlier than Florida V. ashei or Arkansas V. amoenum Ait. populations. One Georgia V. ashei population was only slightly later than tetraploid V. corymbosum. The Florida V. ashei populations continued ripening into late August. The diploid species V. darrowi Camp, V. tenellum Ait., and V. stamineum L., were all basically late in ripening. The potential utility of these species in breeding for both early- and late-ripening Vaccinium genotypes is discussed.
‘Derby’ peach [Prunus persica (L.) Batsch] was released in 1978 to fill the need for an early, large, fresh-market peach. Derby is the name of a town in the North Carolina sandhills.
Flower bud and leaf samples collected from a wide range of native North American Vaccinium populations were tested for the presence of blueberry shoestring virus (BBSSV) using the enzyme-linked immunosorbant assay. The highest disease incidence was found in Michigan (14%), although a few positive samples also were found in Virginia, New Jersey, Maine, Ontario, and Quebec. Of seven species tested, only V. corymbosum L. and V. angustifolium Ait. were infected with BBSSV.
