Narrative
The Agricultural Research Service announces the release to nurseries and propagators of ‘Keepsake’, a mid-season disease resistant spring-fruiting strawberry cultivar. ‘Keepsake’, tested as B1806, was derived from a cross pollination of B1031 by B1181, planned in 2005 by Dr. Kim Lewers and executed in 2006 by Mr. John Enns. ‘Keepsake’ was selected in a Beltsville seedling field in a plasticulture production system in Spring, 2007, by Dr. Kim Lewers and Mr. John Enns. ‘Keepsake’ was further evaluated in plasticulture production by Dr. Kim Lewers and Mr. John Enns at Beltsville in 2008 observation plots and in annual replicated evaluations starting in 2010. ‘Keepsake’ is expected to be best adapted to the mid-Atlantic and northeastern U.S. and adjacent areas. ‘Keepsake’ has consistently shown high yields and low field rot in annual plasticulture at Beltsville, Maryland, with no fumigation or fungicides. ‘Keepsake’ fruit are exceptionally attractive with a showy calyx. The fruits are large, bright red, and have outstanding flavor. They are firm and tough enough for handling, but have a good mouth feel and are juicy. ‘Keepsake’ is our first strawberry cultivar resulting from annual selection for long postharvest shelf life, and has regularly performed better than other cultivars in storage, lasting up to two weeks with little or no rot and maintaining good appearance, flavor, and texture.

Fruiting season in plasticulture at Beltsville is similar to ‘Flavorfest’ and ‘Chandler’. Compared to ‘Flavorfest’, B1806 has a longer shelf life and more conventionally shaped fruit, because ‘Flavorfest’ fruit are quite plump. It has slightly less rain tolerance than ‘Flavorfest, but has withstood over 5.85 inches of rain during its flowering and fruiting period without damage. ‘Keepsake’s average yield over eight years was slightly less than that of ‘Flavorfest’. Like ‘Flavorfest’, B1806 is resistant to anthracnose fruit rot caused by Colletotrichum species present in our fields. Compared to ‘Chandler’, ‘Keepsake’ has a much longer shelf life, because ‘Chandler shelf life is very short. When grown in plasticulture with no fumigation or fungicides, and with sustainable levels of nitrogen fertilizer, ‘Keepsake’ yields are much greater than those of ‘Chandler’, because ‘Chandler requires exceptionally high amounts of nitrogen fertilizer to perform well and is susceptible to the natural levels of anthracnose fruit rot caused by Colletotrichum species present in our fields, while ‘Keepsake’ is resistant. ‘Keepsake’ fruits are larger and have much better flavor and texture than ‘Chandler’, especially after postharvest storage. A plant patent for ‘Keepsake’ has been applied for and is pending.
