Blackberry ( Rubus fruticosus ) and raspberry ( R. idaeus ), belonging to genus Rubus, family Rosaceae, are widespread perennial shrubs. They are known to contain naturally occurring polyphenol antioxidants that can regulate certain beneficial
Blackberries have long been a favorite wild fruit, as many species are native to several countries worldwide and are picked for personal or commercial use. Natural hybrids of wild species provided several of the first named cultivars including, for
and produce fruit in the next growing season. In red raspberry ( Rubus ideaus L.), primocane- and floricane-fruiting cultivars have substantial commercial value. In blackberry ( Rubus subgenus Rubus Watson), floricane-fruiting has been the basis of
Some caneberry ( Rubus L.) production regions experience dramatic seasonal variation in bloom date and fruit ripening time. Phenology and biology of flowering in both cultivated and wild raspberries ( Rubus idaeus L.) and blackberries have been
Most of the cultivated fruit species in Rubus belong to two subgenera: Idaeobatus (raspberry) and Rubus (formerly Eubatus ) (blackberry). Idaeobatus contains european red raspberry ( R . idaeus ), north american red raspberry ( R
Floricane-fruiting blackberry do not produce fruit in the Northern Great Plains region of the United States unless the primocanes are protected by some method such as laying canes parallel to the ground using a rotating cross-arm system and
A variety of techniques and vegetative materials are used to asexually propagate blackberry. Blackberry plants can be easily reproduced from root suckers, crown division, root cuttings, tip layering, soft stem cuttings, and tissue culture (TC
Abstract
‘Silvan’ is a blackberry cultivar of exceptional quality and yield. In Victoria, the cultivar displays greater tolerance to heavy soils, wind and drought, plus greater productivity, fruit size, and jam processing qualities than other commercial cultivars of trailing blackberries such as ‘Boysen’, ‘Marion’, and ‘Young’.
Abstract
Blackberries are classified taxonomically in the genus Rubus, subgenus Eubatus, and consist of a highly variable and complex group of plants. Bailey (1) recognized over 350 species of blackberries, but the taxonomy of the subgenus is still in much confusion. Blackberries range from evergreen, subtropical types to deciduous clones that survive beyond the Arctic Circle. Most are indigenous to the northern hemisphere but some occur in the tropical mountain regions of the southern hemisphere. A naturally occurring ploidy range from diploid (2x = 2n = 14) to dodecaploid (12x = 2n = 84) exists (5). Homoploid blackberry species are mostly interfertile and biological systems encouraging outcrossing are common, thus native populations of blackberries in much of the world are highly hybrid (7). Consequently, it is difficult to assign cultivars to specific species, since progenitors of modern cultivars were selected from the wild.
Abstract
‘Choctaw’ is the fifth in a series of erect-growing, high-quality, productive blackberry cultivars developed in the breeding program of the Arkansas Agricultural Experiment Station. Previous releases from this program are ‘Comanche’ and ‘Cherokee’ in 1974 (Moore et al., 1974a, 1974b), ‘Cheyenne’ in 1977 (Moore et al., 1977), and ‘Shawnee’ in 1984 (Moore et al., 1985). ‘Choctaw’ ripens its fruit earlier in the season than the previous cultivars, thus extending the blackberry fruiting season.
