“…Wynne is recommended for production under irrigation or where annual precipitation is 500 mm or more. In irrigated tests in Utah from 1976 through 1983 (34 site years), the grain yield of Wynne (4389 kg ha −1 ) exceeded that of Fremont (4184 kg ha −1 ) (Dewey, 1972) and ‘Borah’ (4125 kg ha −1 ) (Sunderman and Bruinsma, 1975) hard red spring wheats. It was similar to that of ‘Powell’ (4330 kg ha −1 ) (Albrechtsen, 1981).…”
