La. The Culture and Breeding of Creole Onions , (l) Development 



of yellow and white varieties and strains for American market, 

 strains will be selected from Red Creole, hybrids will be made 

 between red and white and existing yellow varieties; from these 

 crosses, yellow selections will be obtained; (2) establishment 

 of high solid strains having high solids content so as to improve 

 storage quality. Bulbs having high solids content will be 

 selected and planted; progenies of each will be tested; (3) to 

 breed varieties and strains which are resistant to downy mildew 

 and pink root; {U) to develop male sterile lines to be utilized 

 in production of hybrid onion seed; (5) work out most satisfactory 

 cultural methods.

N. Mex. Development of Hybrid Varieties of Onions of the Grano Type . 



To develop one or more first-.generation hybrids that are superior to 

 White Grano and Early Grano in the following: (l) yield; (2) 

 uniform early maturity; (3) uniformity of size and shape and color; 

 (4) resistance to bolting; (5) resistance to pink root disease; and 

 (6) resistance to thrips injury.

Tex. Treatment of Onions to Extend the Marketing Period . To (l) 



develop a commercially practical infra-red post harvest onion 

 treatment; (2) construct an experimental moving belt-type infra- 

 red onion treating apparatus; and (3) learn detrimental effects 

 a standardized infra-red treatment may have on keeping quality of 

 untested commercial varieties.
