Mr. King. — Of two equal scoring exhibits the one with the best 

 pedigree is the one to plant;" 



Dr. Tucker. — Yes, a pedigree based on performance and not on the 

 score card — a pedigree based on the actual yield in the field. 



I had a photograph of some of the ears that I bred from last year. 

 1 photographed all of them so as to get an idea of how they would re- 

 produce themselves in shape and appearance. 



Mr. . — What was the lowest yield per acre? 



Dr. Tucker. — 40 bushels. They ranged from 40 to 156 bushels per 

 acre. 



■ Mr. . — Did you plant by tier or by row ? 



Dr. Tucker. — By row. I did not plant all of the corn on the ear, 

 but from the same place on the ear. Whatever I used I planted from 

 the whole length of the row on the ear. 



Mr. . — Was the ear that produced 40 bushels apparently as 



good as the others ? 



Dr. Tucker. — No, not quite so good. It was a smaller ear than 

 some of the others. I had placed it next to the last. The second best 

 ear produced 1443^2 bushels to the acre. That ear weighed 18 ounces, its 

 per cent of grain was only 81 and we are taught that is very low. The 

 per cent of grain for Boone County White should be 86. This one was 

 way below the standard, and yet the actual amount of grain on that ear 

 v/as 14;^-^ ounces. It lacked only an ounce and a half of putting a pound 

 of grain on that ear. The ear that produced only 40 bushels to the acre 

 had on it only 11^ ounces to the ear. So there seems to be in gen- 

 eral some relation between the actual amount of grain in weight on an 

 ear and the total yield per acre of grain. The ear that gave the small- 

 est yield was a pretty good ear according to the score card. I placed it 

 as No. 17 in my plat, and the one which gave the largest yield I placed 

 as No. 24. These yields were apparent even in the gathering — in the 

 size of ears themselves. 



Mr. Reed. — Where was the seed raised that you planted? 



Dr. Tucker. — In Illinois. 



Mr. Reed. — Was the seed corn pollinated by corn in the same patch 

 or by corn in that neighborhood? 



Dr. Tucker. — It was all the same kind of seed, the Boone County 

 White, and this breeding plat was entirely surrounded by the same 

 variety. 



Mr. . — On what kind of soil? 



Dr. Tucker. — Drained, re-claimed swamp lands near Blodgett, Scott 

 county.
