‘Eclipse’ is a thornless, semierect, high quality blackberry (Rubus subg. Rubus Watson) that has firm, uniformly shaped, dark fruit suited for the fresh market and that ripen in the early season for this type of blackberry. ‘Eclipse’ was released by the U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) breeding program in Corvallis, OR in cooperation with Oregon State University’s Agricultural Experiment Station. ‘Eclipse’ is introduced as a high quality blackberry that has medium-sized, uniformly shaped berries that ripen in the early, semierect blackberry season where it is firmer or earlier than current standards. ‘Eclipse’ and ‘Galaxy’, released with a similar ripening season, have many characteristics in common, including high-quality fruit in the early semierect season and vigorous productive plants; ‘Eclipse’ fruit tend to be more uniformly shaped, slightly smaller and firmer than those of ‘Galaxy’. ‘Eclipse’ should be adapted to areas where other semierect blackberries can be grown successfully. A U.S. Plant Patent, USPP 30,448, was granted.
