Abstract: The present invention is a new and distinct thornless blackberry cultivar named ‘Black Jack’, which is capable of producing large and firm fruit with high soluble solids. The cultivar is characterized by its thornlessness and its fruit attributes. It has the fruit morphology of other very large blackberries grown on thorny cultivars, namely uneven drupelets. It is, however, firmer than other large fruited types, and has very high soluble solids, up to 14%. ‘Black Jack’ plants are also unusual amongst the very large blackberry cultivars in that they produce commercial quantities of fruit, greater than 13 tons per acre on 2 year old potted plants.

Abstract: The present invention is a new and distinct spring bearing red raspberry cultivar named ‘Claudia’ (also tested as KCE-1), which is capable of consistantly producing large numbers of fruit in the spring midseason, the fruit being larger than that of the standard cultivars. The cultivar is characterized by moderate suckering ability, small red thorns and stiff upright canes which are slow to grow in the spring and quick to stop growth in the fall. These traits, along with native cold hardiness traits, has resulted in excellent winter survivability in ‘Claudia’ fruit grown in the northern U.S., east of the Rocky Mountains. Because of the slow growth of primocanes and the upright habit of the flowering trusses, fruit is usually not shaded and well presented during harvest.

Abstract: The present invention is a new and distinct spring bearing red raspberry cultivar named ‘Esta’ (also tested as GEL-114), which is capable of producing large numbers of fruit in the early spring season, the fruit being similar to that of the standard cultivars. The cultivar is characterized by moderate suckering ability, sparse red thorns and very vigorous canes and leaves which are commonly free of fungal diseases until leaves senesce in the Fall. ‘Esta’ has resistance to fluctuating winter and spring temperatures, this has resulted in excellent winter survivability in the Mid-Atlantic States. Because of the rapid growth of primocanes, fruit is usually shaded during harvest and fruit rot can occur if the primocane canopy is not separated from the fruiting canopy.

Abstract: The present invention is a new and distinct thorny blackberry cultivar named ‘Chesapeake’, which is capable of producing very large fruit in the spring midseason, the fruit being much larger and similarly durable than that of the standard cultivars. The cultivar is characterized by moderate suckering ability, recurved thorns and its very flavorful fruit which is edible even when the fruit is immature.

Abstract: The present invention is a new and distinct primocane fruiting red raspberry cultivar named ‘Jaclyn’, which is capable of producing fruit much earlier than that of the standard cultivars. The cultivar is characterized by a vigorous suckering ability and its consistently large, dark, long conic and very symmetrical fruit. Fruit seldom sunscalds in the mid-Atlantic states when grown under standard irrigation and fertilization practices. Fruit aroma is very full, and fruit quality is excellent through even high temperatures. Fruit separation can be difficult in cooler weather.

Abstract: The present invention is a new and distinct floricane fruiting red raspberry cultivar named ‘Georgia’, which is capable of producing large quantities of fruit much earlier than that of the worldwide standard floricane cultivars, ‘Glen Ample’ and ‘Tulameen’. The cultivar is characterized by its thornlessness and fruit with a slightly pileated drupelet. The fruit is also very symmetrical, light colored and round. Fruit aroma is very good and fruit firmness and sugar content is sufficient for shipping long distances.
