EXPERIMEN'TS WITH INDIAN CUKN. 



K. Y. AfiRICPLTCRAL EXPERIMKNT STATION, 



Geneva, N. Y., Dec. 8, 18S3. 



On May 1 6th, 1 35 kinds of corn were 

 jjlanted in the garden, vsath the inten- 

 tion of promoting the cross fertilization 

 of the varieties in order to study the 

 effects. The seed used was some of it 

 selected on account ot its purity ; other 

 .seed was from named varieties, still other 

 seed from varieties purposely hy'oridized, 

 or presumed from their appeai-ance or 

 location on the ear to be hyVjridized ; 

 and seed which possessed peculiarities 

 in appearance. The types represented 

 were the three kinds of pop corns, the 

 flint pop, the pearl pop, and the rice 

 [jop ; the flints in eight-rowed and 

 twelve-rowed varieties, and soft or Tus- 

 carora's ; the sweets in two or more 

 types of ear, the one corresponding to 

 the flint, another to the dent corn ear; 

 and the dents also in two or more types, 

 the eight-rowed with broad kernel, and 

 another, the many rowed, with deep 

 kernel. We also had a pod oi* husk 

 corn. 



Through a study of the crop from 

 these various seeds, we are enabled to 

 make some general conclusions, which 

 probably are suflicient to generalize 

 from, but which certainly apply to the 

 case in hand. 



The seed of the preceding year gives 

 uniformity of ear ; that Ls, a dent corn 

 seed may produce an eight-rowed flint, 

 or an eighteen-rowed dent, but each ear • 

 will be perfect of its kind, and will be 

 free from kernels of other type than its 

 own. The flint corn kernel may pro- 

 duce .several varieties of flint corn ear, 

 or dent corn eai', but there will Vje no 

 variety in the kernel upon the ear ; a 

 dent corn seed may furnish a sweet 



corn ear, and dent corn ears, but not 

 mixed u{)on the cob. A pop-corn kernel 

 may produce a sweet corn ear. of sweet 

 corn type, a sweet com ear of pop-coi^n 

 type, or a pop-corn ear of the various 

 types, without admixture of kernels 

 upon the ears. 



On the other hand, hybridization of 

 the current year produces changes in 

 the kernel, so that one ear of corn may 

 bear kernels of various coloi's, and of 

 various types, the tendency, however. 

 Vjeing for the shape of the kernel to be 

 governed by the type of the maize ear 

 upon which it is found. 



The a])pearance of various types upon 

 an ear allow of some curious general- 

 izations. Thus, the rice pop kernel 

 form does not appear upon ears of other 

 character, nor does the pearl pop kernel 

 form appear upon the rice pop eai'. The 

 flint pop does not seem to appear upon 

 either the rice or the pearl pop type so 

 far as form is concerned, but its struc- 

 ture, however, influences. Sweet corn, 

 however, appears upon the three types 

 of pop-corn indiscriminately, but, on the 

 other hand, the pop-corns do not appear 

 upon the flint corn ears. While flint corn 

 appeal's abundantly on sweet corn ears, 

 on the other hand, .sweet com does not 

 appear upon the flint corns. Dent corn 

 kernels will appear upon the sweet corn 

 whose type of ear Ls that of the dent 

 ear, but not upon sweet corn whose 

 type is that of the flint ear. 'i'he dent 

 corn, again, does not appear upon the 

 flint ear, but in some isolated instances 

 the flint corn kernel may appear upon 

 the dent ear. 



The appearance of kernels of one 

 variety upon ears of another variety, for 

 each of the types, is of frequent and 

 constant occurrence, except in the case 

 of red ears. The red ears have a con- 

 stancy of color which is truly remarka- 

 ble : where sweet com apjjears upon 

 red pop and red dent ean? the sweet 

 corn partakes of the red color.
