Discussion of 1907 Results. — Essentially the same results 

 are shown here as in the preceding season. Of the seven (7) 

 originals in Gronp I. all of the progeny dropped distinctly 

 below the original standard, showing 55.99 per cent of 

 t^'pical kernels, while the eight samples in Group II. carrying 

 distiuctlv starch kernels in the originals, all increased bv about 

 the same amount as the others dropped, the average per cent of 

 typical kernels in the progeny being 55.2 per cent, or less than 

 0.7 per cent below those of Group I. 



In the group of typical kernel original, only one out of seven 

 increased in protein content, the average per cent in the originals 

 being 12.79 against 11.20 per cent in the progeny, or a drop of 

 1.59 per cent. In Group II. consisting entirely of the distinctly 

 starchy kernels, there was a universal increase in the typical 

 kernels in the progeny, and three out of eight increased in protein 

 content, the averages being 10.65 per cent for the originals and 

 11.02 per cent for the progeny. Group III showed 58.1 per 

 cent typical kernels in the originals and 64.1 per cent in the 

 progeny, an increase of 6 per cent: and 11.50 and 12.25 per 

 cent total protein, respectively. 



Summarizing by groups as in the results of the preceding 

 year, the figures appear as below:
