Days Main Uses Cesrake Beans 9 
® 
To assure freedom from seed-borne bacterial blight and anthracnose, Keystone bean 
seed is grown in Idaho’s Magic Valley and certain selected areas of California where 
these diseases cannot survive. 
Germination of bean seed is mainly a function of the handling that the seeds receive. 
Keystone: bean seeds are threshed on big, gentle machines, and handled with the great- 
est care in processing and shipping. Just one example of such care is the lining of all 
our bins with rubber, to cushion the seeds’ fall. 
While theses things are of greatest importance, appearance is not neglected. Every lot 
of Keystone bean seed is sawdust-polished, then handpicked to remove split or deformed 
seeds and foreign matter.
