RESULTS OF SPRING WHEAT VARIETIES GROWN IN COOPERATIVE PLOT AND NURSERY 
 EXPERIMENTS IN THE SPRING WHEAT REGION IN 1971
 
 The year 1971 was the 43rd 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 
 and (3) the international sawfly yield nursery. Nurseries were grown in 
 Minnesota, Montana, North Dakota, South Dakota, Nebraska, Idaho, Wyoming, 
 Washington, Canada and Wisconsin.
 
 The decision was made to omit the section on "Results from State-Planned 
 Yield Trials" from Regional Report. If you are interested in having this 
 information, you may contact the individual state cooperator directly.
 
 NEW VARIETIES
 
 Three hard red spring wheat varieties were released to the farmers:
 
 BOUNTY 208 - Awned, early semidwarf with high lodging resistance. Resistant 
 to stem and leaf rust. High yield and medium bushel weight. High incidence of 
 necrotic lesions on leaves. Limited quality data indicate low in protein and bake 
 absorption. Parentage not disclosed. Released by Cargill, Inc., in 1970. (C.I. 
 15078)
 
 LARK - Awned, early semidwarf with high lodging resistance. Resistant to stem 
 and leaf rust. Moderately susceptible to black chaff. Limited data indicate high 
 yield and medium bushel weight. Quality data show lower protein and bake 
 absorption than Chris. Parentage not disclosed. Released by World Seeds 
 Incorporated in 1971.
 
 NORDAK - Awned, medium height and maturity. Insufficient data on yield, 
 quality and disease resistance. Selected as a single plant in a field of durum 
 wheat by A. H. Berg, Barney, North Dakota. Released to farmers in 1971.
 
 Two durum wheat varieties were released to the farmers:
 
 ROLLETTE - Awned, early, medium height and medium lodging resistance. 
 Resistant to stem rust but moderately susceptible to leaf rust. High yield and 
 high bushel weight with large kernels. Quality is satisfactory for semolina 
 products. Selected from crosses involving Ld. 393, Langdon, Ld. 398, Ld. 357 and 
 St 464. Released jointly by the North Dakota Agricultural Experiment Station and 
 the Plant Science Research Division, Agricultural Research Service, U. S. 
 Department of Agriculture in 1971. (C.I. 15326)
 
 WASCANA - Awned, early, medium height and medium lodging resistance. 
 Resistant to stem and leaf rust. High yield and medium bushel weight with large 
 kernels. Quality is satisfactory for semolina products. Selected from crosses 
 involving LK2* and Pelissier. Released by the Canada Department of Agriculture at 
 Winnipeg in 1971. (C.I. 15280)
 
 ASSIGNMENT OF C.I. NUMBERS
 
 This is a reminder that C.I. numbers are assigned to selections, genetic 
 material, etc., only upon request of parties concerned, except for varieties 
 which are named and released for public use. If you have materials that should be 
 added to the world collection maintained by Plant Science Research Division at 
 Beltsville, please apply for a C.I. number and submit seed to Dr. J. C. Craddock.
