Kans • Investigations of Mosaic and Other Virus Diseases of 



Hard Red Winter Wheat . To (l) discover additonal means of 

 virus transmission and spread; (2) find additional sources or 

 reservoirs which harbor the virus; (3) discover more cultural 

 practices which will aid in control; (4) find resistant 

 parent'al stock for breeding; (5) obtain varieties of hard 

 red winter >rtieat more resistant than those now grown^ and 

 (6) conduct basic research on the virus.

Mo. Breeding and Evaluating New Strains of Soft Wheat with 



Resistance to Leaf Rust. Loose Smut, and Hessian Fly . To breed 

 an improved strain of soft wheat for Missouri, combining leaf 

 rust, loose smut and Hessian fly resistance in a high yielding 

 strain with good quality, using extensively N fertilizers and 

 working for an early, short, stiff -strawed variety; and 

 comparing any new strains originating from this project with 

 standard varieties to find relative merits, and quality of 

 grain by tests to learn its commercial use.

Nebr. Cytogenetic Studies of Economic Characters, Such as 



Stature and Resistance to Bunt and Rust, ifi Nebraska Winter 

 Wheats by Means of Aneuploids and Irrigation . (l) Substitute 

 individual chromosomes from Nebraska winter wheat varieties, 

 with immediate emphasis on Cheyenne, into a uniform genetic 

 background, as Chinese Spring, to learn effect of specific 

 winter wheat chromosomes. (2) Develop a set of aneuploid 

 stocks in Cheyenne for use in chromosomal substitutions from 

 other varieties, species, or genera. (3) Locate specific 

 chromosomes of genes for characters as stem rust resistance 

 in Cheyenne and stature in various Nebraska selections. (4) 

 Transfer desirable characters from other varieties, species, 

 or genera to Cheyenne by aneuploids and irradiation-induced 

 translocations .
