3S. Investigation of Pepper Diseases and Their Control Under 



Mississippi Conditions . To (1) determine diseases on peppers 

 in State and relative crop damage; (2) seed control of major 

 diseases of economic importance; (3) survey all seed stocks 

 for possible resistance and incorporate desirable resistance 

 into suitable types; and (A) develop techniques for rating 

 disease reaction, 

 PI. Path. HL-9 



3S. Nematode Resistance in Peppers . Investigation of resistance 



to root-knot nematodes found in certain strains of pepper. 

 Determine mode of inheritance of resistance. Transfer, if found 

 feasible, such resistance to commercially desirable varieties of 

 pepper. 



PI. Path. HL-12, RRFL-2 (S-19) 



H. Testing Tomato Varieties and Selections for Resistance to 



the Early Blight (Alternaria Solahi) and Late Blight (Phytophthora 

 Infestans) Pathogens . Find sources of resistance to (l) 

 Alternaria solani ; (2) various races of Phytophthora infestans ; 

 (3) test tomato plants grown from irradiated seeds for resistance 

 to A. solani ; (0 progeny of resistant selections for disease 

 resistance, and learn methods of inheritance of disease resistance.

Mex. Improvement of Chile (Capsicum Annuum) for Pod Type t Yield. 

 Earliness. Pungency and Resistance to Diseased To (l) develop 

 one or more new varieties of chile which combine better characters 

 of College No. 9, College No. 6, and "Native" varieties, including 

 early maturity; high yield; large, smooth pungent pod; etc.; and 

 (2) complete improvement of a strain of No. 6 type which will be 

 suited for use as fresh green vegetable and for commercial canning 

 and freezing, with such characters as long, smooth, fleshy pod; 

 early maturity; and high yield.
