Mont • Development by Testing and Selection of Varieties of 

 Sugar Beets Resistant to Aphanomyces. Rhizoctonia. and 

 Fusariiim Root Rots . To (l) test resistance of new varieties 

 of sugar beets to Aphanomyces . Rhizoctonia . and Fusarium 

 root rots; and (2) learn if resistance is correlated with 

 certain environmental factors such as temperature, percentage 

 of moisture in soil, soil type, and soil nutrients, and learn 

 reaction of various strains of these organisms on best 

 varieties.

Nebr. The Etiology and Control of Soil-Borne Diseases of 



S\igar Beets . To determine (l) identity of the organisms 

 causing pre- amd post -emergence damping-off of seedlings, 

 root rots, wilt, and storage rots following these diseases, 

 and effect of cropping systems, cultural practices including 

 seed treatments, soil types, and environmental factors on 

 occurrence of these diseases; and (2) factors for resistance, 

 and discovery of resistjuit parent stocks.

La* A Study of a Species of Pythium in its Action- on Sugar 



Cane . The effect of environment will be studied by growing 

 corn and cane under different conditions of temperature, 

 moisture and acid, with Pythium both absent and present, and 

 best temperatures will be determined for infection by work 

 with incubators. Infection will be studied by inoculating 

 roots with Pythiim and sectioning on the microtome, giving 

 the methods of entrance and spread. Various soils will be 

 used, some washed and steamed, to determine soil relation 

 to development of rot and infection. Root systems of the 

 newer varieties will be studied in regard to susceptibility 

 to infection. Antibiotic organisms from the soil will be 

 isolated and studied to determine their role in the soil and 

 in infection.

La. To Develop New Vairieties of Sugar Cane . To develop 



throu^ the breeding of pedigreed sugar cane new varieties 

 and strains which will improve yields per acre.
