| Abstract:
Ribes uva-crispa L. ‘Jeanne’ is a late-ripening, dark red, dessert gooseberry with an unknown European pedigree. This genotype has been observed for 24 years in Oregon, under the selection numbers O.T. 126, CRIB 11, and PI 555830. It was donated to the USDA ARS National Clonal Germplasm Repository (NCGR) in 1981, from the Ribes collection maintained by the USDA and Oregon State University, Department of Horticulture, in Corvallis, Oregon. Its origin prior to Corvallis is undocumented. ‘Jeanne’ was named in honor of the late Ms. Cheryl Jeanne Gunning, who worked in the tissue culture laboratory of the NCGR from 1981 to 1985. ‘Jeanne’ buds break during the last week of March in Corvallis, Oregon. Full bloom occurs in mid- to late-April, about one to two weeks after blooms of R. uva-crispa ‘Malling Invicta’ or ‘Captivator’. The fruit ripens from mid- to late-July, about one week later than the fruit of ‘Malling Invicta’ or ‘Captivator’, and is ripe for about one week. The fruit ripens to a deeper red than those of ‘Captivator’. The fruit weighed about 5.0 g/berry (7 year average), tended to be smaller than those of ‘Malling Invicta’, but larger than those of ‘Captivator’. The yield from ‘Jeanne’ is higher than from many other gooseberry plants. The fruit taste is full, sweet, and improved over ‘Captivator’. The plant tends to be somewhat spreading, growing to 1.5 m x 1.5 m, and has single, nodal thorns. The leaves and fruits of ‘Jeanne’ are highly resistant to powdery mildew, caused by Sphaerotheca mors-uva (Schwein). Berk. & Curt. The leaves are also highly resistant to white pine blister rust, caused by Cronartium ribicola Fisher. Damage from aphids (Capitophorus ribis L.) or defoliation from sawflies (Pachynematus spp.) is less severe on ‘Jeanne’ than in other European gooseberries. Black leaf spot, caused by Drepanopeziza ribis (Kleb.) Hohn, is visible on some leaves in summer, but does not appear to cause plant damage. We recommend this cultivar for home plantings or commercial gooseberry production in the Pacific Northwestern United States and in other temperate climate zones. We expect that this cultivar will be good for organic production because of its pest resistance and very good fruit quality. It could extend the production season of red gooseberries beyond that of ‘Captivator’. | |
