Onions and Root Crops 



Colo. The Development of Onion Varieties and Hybrids Adapted 



to the Major Onion Growing Areas of Colorado . (1) Incorporate 

 resistance to pink root, purple blotch, and important storage 

 diseases; (2) obtain yields per acre higher than now obtained; 



(3) select for high quality with emphasis on firmness and shape 

 of bulb, outer scale color and ability to adhere during storage 

 and handling, and lack of sprouting during storage.

Idaho Breeding Hybrid Onion Varieties for Storage and Dehydration 

 in Idaho . To develop (1) hybrid onion varieties having high 

 yielding ability, improved appearance and storage duality, and

Idaho Factors Responsible for the Occurrence and Dissemination 

 of Epiphytotoics of the Neck-Rot Disease of Onion . (1) Learn 

 when initial infection occurs; (2) follow progress of organism 

 from infection through disease cycle; (3) conduct chemical control 

 experiments as foliar field spray or dust and storage treatment; 



(4) study progress of disease in storage; and (5) cull onion piles 

 and warehouse dumps for spore spread and dissemination; (6) learn 

 if disease is accumulative under continuous cropping practices.
