Blackberry Galaxy is a newest thornless, semi-erect high-quality cultivar, that has firm, large, dark fruit suited for the fresh market and that ripen in the early season for this type of blackberry. Galaxy was released by the US Department of Agriculture – Agricultural Research Service breeding program in Corvallis, Oregon, in cooperation with Oregon State University’s Agricultural Experiment Station.
Galaxy was introduced as a high-quality blackberry that has medium-large berries that ripen in the early, semi-erect blackberry season when it is firmer or earlier than current standards. Galaxy should be adapted to areas where other semi-erect blackberries can be grown successfully.
The pedigree of Galaxy is the same as Eclipse, but the cross was made 1 year earlier. Blackberry cultivar Galaxy and Eclipse have many characteristics in common, including high-quality fruit in the early semi-erect season and vigorous, productive plants.
Firm, medium-large fruit that have excellent fruit quality ripen early in the semi-erect blackberry season, and have excellent flavor that distinguishes Galaxy from most other semi-erect cultivars.
Galaxy has moderate yielding, with yields greater than those for Navaho. Galaxy fruit are more attractive and uniform than those of Navaho, Ouachita, and Triple Crown. The fruit skin toughness for the cultivars in the trial are similar except for Triple Crown, which had a very tender skin.
Galaxy begin ripening before Navaho and reaches its 50% harvest date more than a week ahead of Navaho. Harvest season starts at the end of July and continues for 4 weeks. Galaxy has fruiting laterals that are comparable in length and strength to those of Navaho, and shorter, stronger, and less droopy than those of Chester Thornless and Triple Crown.
Galaxy nuclear stock has tested negative for Arabis mosaic virus, Cherry leaf roll virus, Cherry rasp leaf virus, Prunus necrotic ringspot virus, Raspberry bushy dwarf virus, Raspberry ringspot virus, Strawberry necrotic shock virus, Tobacco ringspot virus, Tomato black ring virus and Xylella by enzyme-linked immunosorbent assay. It also tested negative for Apple mosaic virus, Blackberry chlorotic ringspot virus, Beet pseudo yellows virus, Blackberry virus Y, Blackberry yellow vein associated virus, Black raspberry necrosis virus, Raspberry latent virus, Raspberry leaf mottle virus, Rubus yellow net virus, Strawberry latent ringspot virus, and Tomato ringspot virus.
