From Cornell raspberry variety extends harvest into November by Amanda Garris in the Cornell Chronicle 9/15/2011:
“Cornell’s new raspberry variety, Crimson Giant, is fashionably late. Developed by Cornell berry breeder and associate professor of horticulture Courtney Weber (right), Crimson Giant was developed specifically for the New York climate and can extend the harvest window for fresh, local raspberries to the beginning of November.
“‘Consumer disbelief is the real challenge for Crimson Giant,’ said Weber, who works at Cornell’s New York State Agricultural Experiment Station in Geneva, N.Y. ‘They are not accustomed to seeing locally produced raspberries that late in the fall, and they might assume the seller has put a ‘local foods’ sticker on berries from California.'”
[The new variety needs to be grown in high tunnels for frost protection.]
“‘Raspberry yield in high tunnel systems can be many times higher than field-grown plants, due in part to the lower incidence of diseases like gray mold, the ability to grow plants at a higher density and the mitigation of wind that can damage plants,’ said Marvin Pritts, chair and professor of horticulture. ‘The berries are often larger, and the need to manage most pests, diseases and weeds is lower than in the field.'”
