Corn Investigations 
145 
ears yielded 6.46 bushels or 11 per cent more than the rough, 
and 4.27 bushels or 7 per cent more than the original. Of the 
diseased Hogue’s Yellow Dent, the smooth ears yielded 2.6 
bushels or 5 per cent more than the rough, and 1.39 bushels or 2 
per cent more than the original. 
The Nebraska White Prize disease free smooth ears surpassed 
the rough 1.68 bushels or 4 per cent, and yielded 0.12 bushel 
more than the original. In case of the diseased Nebraska White 
Prize, the smooth yielded 1.56 bushels or 3 per cent more than 
the rough, and 2.87 bushels or 6 per cent more than the original 
Nebraska WTiite Prize. 
These data confirm other results favoring the smoother type 
of ear with a somewhat shallow flinty kernel. 
RELATION BETWEEN THE EAR TYPE OF THE SEED PLANTED AND OF THE CROP 
HARVESTED 
The progeny ears produced in the ear-to-row plats of the pre- 
ceding root-rot disease investigation have been classified in 
Table 62 to show the proportion of rough, medium, and smooth 
ears produced from seed ears which had been determined as be- 
ing either badly diseased or disease free by means of the germi-

to-row plats of Table 61 , grouped according to the disease 
condition of seed ears. 1921.
