N. Y. Diseases of Field Corn.—l. Stalk Rot DlBeasc of Field 

 (Cornell) Com. 2. Seed Decay and Seedling Bll^t . To make a survey 

 of the corn disease problems in New York State; study those 

 of the most economic importance; and conduct experimentatiori 

 in an effort to devise an adequate control program. 

 PI. Path. 131-1 & 2 



N. C. Breeding Investigations for the Improvement of Corn Strains 

 Adapted to North Carolina . To (l) develop strains of corn, 

 which are adapted to each area in North Carolina; (2) develop 

 methods of maintaining superior strains iajid aid in multiplica- 

 tion 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. Breeding and Development of Corn for the Shot't 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; (4) 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. 



Agron., PI. Path. 6-6 



Ohio Breeding Field Corn for Ohio . To develop strains of corn 



superior to those now available in the different parts of 

 Ohio.
