LIII. — Experiments in Cross-hreedmr, Indian Corn w 

 vers of the same variety, the seed of which was raised < 

 ndred miles away ; by Professor W. J. Beal. 



1878 1 



Indian 



reported some i -breeding, made 

 corn and with beans The advantage shown by the 



ing of 



in the", 



corn with corn, the seed of which was grown some 

 over that not so crossed was as 151 exceeds 100, 

 ;ase of black wax heans it was as 236 exceeds 100. 



In 1879 and 1880, a similar experiment was made w 

 Indian corn showing that seed from crossed stock produ< 

 corn excelling that raised from uncrossed seed as 109 t Vjj- i 

 ceeds 100, or nearly ten per cent in favor of crossed stock. 



In the spring of 1881, I obtained two lots of white flint co 

 one from Oakland County, the other from Allegan Coun 

 about 100 miles apart. These places are in the same latitu 



iborhood. In one patch of alternate rows of Oakland and 

 *an corn, all of the Allegan c »ra was castrated by pulling 

 the tassels before flowering. On former experiments, cas- 

 >n has been found to cause the ears to grow larger than 

 otherwise would -row. Still, with castration in favor of 

 Uleiran corn, it did not produ.-e ears whirl, were so large 

 ■cnlv developed as did the corn from Oakland County. 

 Oakland County seed corn was the better of the two. 

 ciiiLr to an accident, we faded to raise any pure Allegan 

 in 1881. The "crossed corn" in 1882 was only compared 

 pure Oakland seed raised last year at, this place. 



ssed seed"° were planted in rows alternating with three 

 of pure Oakland County seed of 1881. By an oversight, 



3 " crossed seed" 

 1 stock exceeded 

 exceeds 100.
