RESULTS OF SPRING WHEAT VARIETIES GROWN IN COOPERATIVE PLOT AND NURSERY EXPERIMENTS IN THE SPRING WHEAT REGION IN 1975 The year 1975 was the 47th in the history of the uniform regional testing program. Data summarized in this report were obtained from (1) the uniform regional hard red spring wheat nursery, (2) the uniform regional durum nursery, (3) the international sawfly yield nursery and (4) the secondary sawfly yield nursery. NEW VARIETIES Three hard red spring wheat varieties were named and released that have not been previously reported. KITT - Awned, midseason to late semidwarf with high lodging resistance. Resistant to stem rust and has broader spectrum of resistance to leaf rust than Chris and Era. Tolerant of black chaff, bacterial leaf blight, ergot, and loose smut. Very high yield and medium to low test weight. Milling characteristics are satisfactory. Protein content and bake absorption are lower than Chris, but better than Era. Selected from crosses involving Frontana, Thatcher, Mida, Kenya 117A, Kenya 58, Lee, Newthatch, Pembina, and Polk "sib." Released by Minnesota Agricultural Experiment Station and ARS-USDA in 1975. LEW - Awnless, white chaff, medium height and maturity. Fair resistance to lodging. Moderate resistant to stem rust but ranges from moderate resistant to moderate susceptible to leaf rust. Resistant to stripe rust and wheat stem sawfly. Milling characteristics are satisfactory. Protein content and bake absorption are lower than Chris, but better than Era. Released by the Montana Agricultural Experiment Station and ARS-USDA in 1976.. NEWANA - Awned, semidwarf, medium to late maturity with high lodging resistance. Susceptible to leaf rust but moderately resistant to stem rust. Resistant to loose smut, stripe rust and tolerant to Septoria. High yield and test weight. Milling characteristics are satisfactory. Protein content and bake absorption are slightly better than Era. Released by the Montana Agricultural Experiment Station and ARS-USDA in 1976. One durum wheat variety was named and released. 'Cando' durum wheat, CI 17438, was released by the N.D. Agricultural Experiment Station on December 18, 1975. The ARS-USDA cooperated in its development. Cando has been tested as D7057 in North Dakota since 1971, in regional trials since 1972, and in North Dakota drill strips since 1973. Cando is a spring durum wheat with yellow awns and glumes. Growth characteristics of Cando are semidwarf, medium maturity, and sensitivity to daylength. Cando has been about equal to Ward in grain yield, and higher yielding than Rolette, Wells, and Leeds when grown at locations in the Red River Valley and northcentral North Dakota. Cando is a tall semidwarf (28 inches) with excellent resistance to lodging. Disease reactions have been similar to Rolette. It has been about two days later in heading than Ward. The kernel weight of Cando has been intermediate between Wells and Ward, and its test weight has averaged about one pound per bushel less than Ward. Its overall quality characteristics have been satisfactory for pasta production. Cando was selected as an F4 derived line from the cross Lakota/5/Willet sib// Norin 10/Brevor/3/Langdon/4/Langdon/6/Leeds/7/Brl8O/Wells made in 1966. The short straw characteristic was transferred in 1956 from the breeding line Willet sib//Norin 10/Brevor used in the hard red spring wheat breeding program at NDSU.
