Miss. Inheritance Studies Concerning Yield . Fiber Properties . 



and Disease and Insect Resistance in Upland Cotton * To (1) 

 classify & isolate as far as possible factors which affect 

 yield, fiber properties, & disease & insect resistance, (2) 

 learn when possible genetic ratios expressed by simply in- 

 herited factors & number of factors involved where inheritance 

 is more complex; & (3) learn at what stage in cotton develop- 

 ment, specific factors are operating to produce end results 

 observed,

Mo. Better Cotton Varieties for Southeast Missouri . (1) Breed 



better cottons for Southeast Missouri. (2) Evaluate perform- 

 ance of cotton varieties & new strains. (3) Pursue studies 

 significant to cotton breeding & variety performance as re- 

 lated to genetics, agronomy, physiology, pathology, entomology, 

 & fiber technology.

N. Mex. Breeding Upland Cotton and the Evaluation of Strains and 

 Varieties for Southern New Mexico . To (1) develop strains or 

 varieties of upland cotton that have the following character- 

 istics: high yield, early maturity, strong seedling vigor 

 high tensile strength, high degree of fiber maturity, desirable 

 degree of fineness, staple length of 1-1/16 to 1-1/8 inches, 

 superior spinning quality, resistant or tolerant to Verticill- 

 ium wilt, resistant to bacterial blight, (2) determine adapta- 

 tion of strains & varieties produced in this & other breeding 

 programs to the different producing areas of N. Mex., (3) es- 

 timate grade & staple of cotton produced in N. Mex.

N. Mex. The Genetics of Bacterial Blight Resistance and the Value 



of Osmotic Selection in Upland Cotton . To (1) determine genetic 

 basis of resistance to blight; (2) use induced mutation to ob- 

 tain blight resistance; (3) determine if & in what way osmotic 

 selection can be of benefit in applied cotton breeding work, & 

 (4) perfect techniques for using osmotic selection to best ad- 

 vantage with cotton.
