N. Dak. Breeding and Genetics of Spring Barley* — ^A^ Breeding 

 Spring Barley for Disease Resistance. Desirable Agronomic 

 Characters. Malting and Feeding Quality . To produce 

 varieties which are: (l) resistant to spot blotch, stem 

 rust, and loose smut; (2) satisfactory in malting and 

 f,eeding, and (3) suitable agronomically in yield, straw 

 stiffness and head strength and ease of handling.

N. Dak. Resistance to Barley Leaf Diseases , (l) Locate barley 

 species, or species closely related to barley, which are 

 resistant to one or more barley leaf diseases. (2) Cross 

 these species with varieties of common barley. 

 Agron. 6-l6, Coop. ARS 



Okla. Barley Diseases and their Control . To (l) ^develop test 



for spot blotch resistance in barley, and test varieties from 

 world collection for sources of resistance; (2) determine race 

 or faces of powderv mildew in Oklahoma and test for resistance 

 to these races; (3) grow regional mildew nursery in cooperation 

 with USDA; (4) closely observe breeding material at Stillwater 

 and commercial plantings for appearance of a new disease or 

 outbreaks of diseases whose causal agents are known; and (5) 

 establish root disease garden v^ere resistance to root diseases 

 can be evaluated.

Pa. Scald Resistance in Winter Barley , (l) Search for sources 



of scald resistance in barley so that parental material may be 

 available for breeding scald resistant winter barley, (2) learn 

 if scald problem is due to one or more pathogenic races of 

 Rhynchosporium secalis . (3) investigate methods of inoculation 

 to find best method for large scale outdoor testing, (4) learn 

 if organism is seed borne.
