Comment: 'Sweetie Pie' is a thornless, erect blackberry originally selected by Dr. Creighton Gupton (USDA_ARS) and developed and released by Dr. Stephen Stephen Stringer. This new cultivar was developed from crosses among heat tolerant and rosette disease reistant parents. In replicated trials in south Mississippi over the last decade, 'Sweetie Pie' performed well having good growth and vigor, productivity, resistance to rosette disease, good fruit quality and excellent flavor, and a relatively late ripening season that will aid growers in filling the void between early and late season cultivars. 'Sweetie Pie' is recommended for use by local fresh market and U-pick farm operations as well as homeowners although berries may be too soft for use in commercial production.

Narrative
Rosette or double blossom is a serious disease of most erect blackberries and probably the most limiting factor in blackberry production in the southern United States. The cultivar 'Humble' has been reported variously as immune or tolerant to rosette. A breeding program was initiated at Poplarville, Miss. with the objective of breeding thornless cultivars with rosette resistance derived from 'Humble'. A productive rosette resistant plant (MSUS29) was identified from the cross 'Humble' X 'Brazos'. MSUS29 was backcrossed to standard cultivars and thornless cultivars. An elite thornless selection 'Sweetie Pie' (MSUS119) was identified from crosses with the thornless cultivar 'Navaho'. The most recent crosses were made between selections with 'Humble' as the source of rosette resistance and either 'Arapaho' or MSUS119 as the source of thornlessness. It is a challenge to select rosette resistant plants because we have not been able to develop a reliable screening procedure and all seedlings are screened in the field using natural infection. To determine the tendency of 'Humble', 'Brazos', and 'Rosborough' to transmit rosette resistance, we studied its heritability in blackberry. Only 'Humble' transmitted enough resistance to be usable as a parent. We evaluated the effect of rosette on ripening date, yield, and berry weight. Berries ripened about the same time and weighed about the same when grown at either a rosette-free or disease- present location. However, yield was reduced on some clones and not others where rosette was present.
