■3a. Cotton Breeding . To develop (1) a high yielding cotton 



with a staple of 1 inch or longer which is wilt resistant & 

 (2) new strains or varieties having superior qualities of 

 disease & insect resistance, earliness, & yielding ability 

 combined with special foliage branching, & picking qualities 

 needed to meet the requirements of mechanized farming. 

 Agron. , Crops 26 Coop. ARS 



Ga. Upland Cotton Breeding for Coastal Plain Conditions . 



To (1) develop high yielding cottons adapted to Coastal Plain 

 area which possess superior fiber qualities, with emphasis 

 on high fiber strength with acceptable levels of yield and 

 for resistance to fusarium wilt; & (2) study methods prevent- 

 ing damage to seeds and fibers due to high rainfall and high 

 humidity conditions at harvest.

La. Cotton Breeding and Varietal Evaluation , (l) Study fiber 



characteristics of strength, fineness, length, uniformity, 

 lint percentage, & yield & influences of plant type, & leaf 

 pubescence in proving or developing varieties adapted to state 

 conditions. (2) Learn relation between above characteristics 

 & predicted quality of yarn expected by confirming predictions 

 in spinning trials. (3) Develop & coordinate a comprehensive 

 evaluation program at Baton Rouge, St. Joseph, LeCompte, Bossier 

 City, & Calhoun. (4) Evaluate influence of mechanical harvest- 

 ing on the grade & quality of cotton. (5) Continue breeding 

 for improvement of variety Stardel.

La. A Study of Genetic Factors Involved in Yield Potential 



Fiber~"Quality and Disease Resistance in Cotton. Study: (l) 

 nature of inheritance of & interrelation among quantitative 

 characters concerned with yield & fiber properties in crosses 

 within upland cotton & in crosses between G. hirsutum (upland) 

 & G. barbadense (Sea Island); (2) nature of inheritance of re- 

 sistance to rootknot nematodes. (3) Evaluate effect of re- 

 current selection on frequency of desirable genes in crosses 

 between varieties of upland cotton & interspecific hybrids of 

 upland x Sea Island.
