Colo. Testing Foreign Bean Introductions for Resistance to Root 



Rots- and Other Diseases^ To (1) determine resistance of foreign 

 introduction and other sources of germplasm to root rotting 

 organisms of beans; (2) determine compatibility of most promising 

 selections in crosses with best varieties of beans now grown; 

 (3) initiate breeding program whereby new or improved varieties 

 resistant to organisms causing root rots will be developed; and 

 (A) determine, incidentally, resistance of foreign introductions to 

 other diseases common to the region.
