Sept. 23, 2015, Durham, NH – A University of New Hampshire scientist has developed a new cherry tomato designed to be grown in hanging baskets in greenhouses.

“Rambling Rose” provides a new attractive pink fruit colour not yet available in cherry tomatoes suitable for hanging basket production. (Click on photo for more information.)
 
The new fruit was developed by Becky Sideman, a researcher with the NH Agricultural Experiment Station and extension professor of sustainable horticulture production, and her collaborators Elisabeth Hodgdon at the University of Vermont and Jennifer Noseworthy of Gordon College. Both are former UNH graduate students and worked on the development of Rambling Rose while at UNH.
 
“Rambling Rose” originated from self-pollinating a single hybrid Tumbler cherry tomato plant at UNH in 2009. Tumbler was selected as the parent material due to its desirable uniform growth and fruiting habit.

PEDIGREE SELECTION PROCESS

Plant selections were made in subsequent generations using pedigree selection, choosing the best plants from the best families grown in both greenhouse and field settings at the NH Agricultural Experiment Station, until uniformity in plant and fruit phenotype was achieved in the seventh generation of plants.
 
“Our goal was to select plants with attractive and symmetrical branching, uniform leaf canopy, and plentiful fruit set. Because hanging basket tomatoes are grown not only for their yield, Rambling Rose was developed with aesthetics of vegetative growth in mind as well,” Sideman said.
 
Overall fruit quality, earliness, yield, and growth habit of Rambling Rose were comparable to or better than the commercially available cultivars evaluated in 2012 and 2013 in trials at the University of New Hampshire.
Other cultivars evaluated include Lizzano, Terenzo, Tumbling Tom, Tumbler, Cherry Cascade, and Sweetheart of the Patio.
 
SOURCE FOR SEEDS

Those interested in commercial seed production should contact Becky Sideman, University of New Hampshire, G48 Spaulding Hall, Durham, NH 03824. Small samples of seed for research or trial are available.
 
The research findings are reported in the June 2015 issue of HortScience in the article “‘Rambling Rose’: A Pink-fruited Cherry Tomato for Hanging Basket Production.” This material is based upon work that is supported by the National Institute of Food and Agriculture, U.S. Department of Agriculture, under award number 228522.
 
Founded in 1887, the NH Agricultural Experiment Station at the UNH College of Life Sciences and Agriculture is UNH’s original research centre and an elemental component of New Hampshire’s land-grant university heritage and mission.

It stewards federal and state funding, including support from the USDA National Institute of Food and Agriculture, to provide unbiased and objective research concerning diverse aspects of sustainable agriculture and foods, aquaculture, forest management, and related wildlife, natural resources and rural community topics.

It also maintains the Woodman and Kingman agronomy and horticultural farms, the Macfarlane Greenhouses, the Fairchild Dairy Teaching and Research Centre, and the Organic Dairy Research Farm. Additional properties also provide forage, forests and woodlands in direct support to research, teaching, and outreach.
 
The University of New Hampshire, founded in 1866, is a world-class public research university with the feel of a New England liberal arts college. A land, sea, and space-grant university, UNH is the state’s flagship public institution, enrolling 13,000 undergraduate and 2,500 graduate students.
