La. Transfer of Genes for High Quality of Fiber from Goss- 



)ium Barbadense to American Upland Strains of Cotton* To 



[1) attempt to combine the superior length, strength, & fine- 

 ness of fiber in strains of species Gossypium barbadense with 

 the high yield, high lint percentage & early maturity of vari- 

 eties of Upland cotton now grown, & (2) test effectiveness of 

 new methods of plant breeding in combining genes for desirable 

 quantitative characters by interspecific hybridization. 



Agron. 852 Coop. ARS 



Miss. Cotton Improvement Through a Genetic Study of the Intro- 



duction of Genes from the Diploid American and Other Diploid 

 Species of Gossypium . To study inheritance of certain char- 

 acters, such as gossypol, oil, bract size & lintlessness, in 

 cottonuusing crosses involving hirsutum as one parent & segre- 

 gates from a species hybrid, hirsutum x ( armourianum x thur- 

 berii), as the other.

Miss. A Comprehensive Collection of Stocks of Mendelian Charac- 



ters. Principal Commercial Varieties and Selected Inbred Lines 

 of Upland Cotton . To (1) maintain a genetics garden & a cata- 

 logued seed supply of characters segregating in Mendelian ratios; 



(2) maintain a catalogued supply of viable seed of all commercial 

 varieties & certain selected inbred lines of cotton; & (3) screen 

 material of upland or Sea Island Stocks collected in other coun- 

 tries, evaluate it, & add to the Regional Collection those having 

 desirable or outstanding characteristics.

Miss. Fundamental Studies of Properties of Cotton Species, and 



the Development and Use of Techniques to Facilitate the Trans- 

 ference of Desirable Characters to Upland Cotton . To (1) main- 

 tain and propagate cotton species, interspecific hybrids, & 

 other stocks necessary for prosecution of fundamental cyto- 

 genetic experiments in progress, or to be started, & to procure 

 other stocks or materials as may be required; (2) survey basic 

 stocks, certain hybrid progeny & various derived lines for de- 

 sirable plant characters & fiber properties; (3) study critically 

 the cytogenetic problems in transferring these characters & prop- 

 erties to a stable Upland cotton background; & (4) develop & ex- 

 tend experimental techniques to be used in character transference 

 study.
