75 days. Early season sweet corn that yields well in cool climates, Dorinny was originally a Canadian cross between Golden Bantam and Pickaninny. Received a Market Gardeners’ Award of Merit in 1936. Reliable even where soils are cool. Yellow kernels on 6- to 7-inch cobs offer old-fashioned sweet corn flavor. Plants reach 4-5 feet in height and usually yield two ears per plant. Grown in northern Maine by our friend, activist-farmer Jim Gerritsen.
