N. Dak. Breeding and Development of Corn for the Short 



Growing Season Areas Prevalent in North Dakota . To (l) 

 isolate new inbred lines of corn which are adapted to the 

 environmental conditions of the short and cool growing 

 seasons of this area and which possess desirable agronomic 

 characters (good ear height) and resistance to diseases 

 (stock rot) and insects (corn borer); (2) improve the 

 plant and seed characters and resistance to diseases and 

 insects of inbred lines now used in early maturing hybrids 

 by outcrossing to selected inbreds of desired character 

 and backcrossing and/or selfing and selection; (3) introduce 

 and study the adaptability of inbred lines originated in 

 other Northern State Experiment Stations for use in North 

 Dakota; (k) intercross and study combining ability and 

 adaptability of selected inbred lines in top, single and 

 double cross combinations as a prerequisite to the 

 recommendation and release of new hybrids for commercial 

 production; and (5) test reaction of North Dakota inbred 

 lines with the cytoplasmic male sterile character for the 

 purpose of possible use of cytoplasmic male sterility in 

 commercial seed production.

Ohio 



The Insect Phases of the Corn Research Program . To 

 (l) identify and obtain information on relative importance 

 of factors influencing abundance of borers in corn plant; 

 and (2) gain better understanding of relationships of 

 environmental factors to fluctuations, oscillations, and 

 levels of abundance of corn borer populations. 



Eat. Ill (NC-20) 



Okla, 



Breeding of Disease-Resistant Wheats Adapted to 

 Oklahoma . To breed for (1) higher yield through more and 

 larger seeds; (2) grain with higher test weight per bushel 

 and with satisfactory kernel appearance; (3) disease 

 resistance; (U) cold and drought resistance; (5) stiff er 

 straw, non- shattering, and early maturity; and (6) varieties 

 with suitable milling and baking characteristics.
