N, C, Breeding Investigations for the Improvement of Corn 



Strains Adapted to North Carolina , To (1) develop strains 

 of corn which are adapted to each area in North Carolina; 

 (2) develop methods of maintaining superior strains and 

 aid in multiplication of such strains; (3) study breeding 

 methods and genetic mechanisms related to corn; and (4) 

 study inheritance of resistant factors in the host to 

 important insects and diseases of corn under local 

 conditions,

N, Dak, Hard Red Spring Wheat Improvement , To (1) search 

 foreign wheat collections of USDA for wheat varieties 

 and relatives carrying desirable characters lacking in 

 presently grown commercial hard spring wheat varieties; 

 (2) combine desirable characters by crossing with best 

 commercial varieties and new hybrid selections of hard red 

 spring wheat; (3) make extensive plans and head selection 

 from crosses in segregating generations and test progenies 

 in nursery experiments to establish superiority and 

 adaptability to spring wheat region; (4) establish milling 

 and baking quality characteristics of prospective new 

 wheats; and (5) increase superior wheats for release to 

 growers,
