Overview
Wisconsin 55 was bred at the University of Wisconsin by plant pathologist J.C. Walker and released in 1947, selected out of crosses whose parents included Early Biltmore, Redskin, John Baer and Del Monte. The aim was resistance to early blight and leaf spot, and it also tolerates Fusarium wilt; it went on to be one of the most planted home garden tomatoes in the upper Midwest for decades. The round, deep red fruit of about 5 to 8 ounces resists cracking and stays firm, so it slices, cans and cooks well. Plants are indeterminate and benefit from staking, which keeps the foliage aired. Start seed indoors 6 to 8 weeks before the last frost and plant into warm soil.
