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

 and Varieties for Southern New Mexico * To (l) develop 

 strains or varieties of upland cotton that have the following 

 characteristics: high yield, early maturity, strong seedling 

 vigor, high tensile strength, high degree of fiber maturity, 

 desirable degree of fineness, staple length of I-I/I6 to I-I/8 

 inches, superior spinning quality, resistant or tolerant to 

 Verticillium wilt, resistant to bacterial blight, (2) determine 

 adaptation of strains and varieties produced in this and other 

 breeding programs to the different producing areas of New 

 Mexico, (3) estimate grade and staple of cotton produced in 

 New Mexico.

N. Mex. Variety Test of American Upland Cottons Suitable for 



Combed Yarns . Learn the adaptation of selected high quality 

 American Upland cotton varieties to southern New Mexico as 

 measured by; yield of lint, boll size, gin turnout, lint 

 index, seed index, earliness of maturity and seedling emergence; 

 fiber properties as Upjier half mean length, length uniformity 

 ratio, fineness, maturity, strength and elongation; yarn 

 strength and appearance grades, nappiness, comber waste and 

 occurrence of ends down; tolerance to Verticillium wilt.

N. Meoc. The Genetics of Bacterial Blight Resistance and the 



Value of Osmotic Selection in Upland Cotton . To (l) determine 

 genetic basis of resistance to blight, including problems of 

 allelism, gene interaction, pleiotropy, and linkage; (2) use 

 induced mutation to obtain bli^t resistance in agronomic ally 

 desirable but susceptible material, as well as to obtain new 

 types of resistance; (3) determine if and in what way osmotic 

 selection can be of benefit in applied cotton breeding work, 

 and (Zf) perfect techniques for using osmotic selection to 

 best advantage with cotton.
