Keport of Corn Pollination. II. 



By M. L. Fisher. 



The work reported in 1908 was cnntimiecl in 1909. The seed from the 

 different crosses reported in the Proceedings for 1908 was planted in 1909. 

 In each lot a number of ears were self-fertilized by hand pollination, 

 d^ Boone County White, male ; Reid's Yellow Dent, female. 



Forty ears were pollinated. Four were pure yellow and thirty-six were 

 mixed. In a count of 2.000 kernels from mixed ears, 204 showed pure 

 yellow, 27G pure white, and 1,520 mixed white and yellow, often cream 

 color. In this connection it is to be noted that it is difficult to tell when 

 a kernel is pure white. The yellow tinge may be so faint that the most 

 careful examination in a good light may not detect it. 



d". StowelTs Evergreen (Sweet), male; Reid's Yellow Dent, 

 female. 



Forty-seven ears were hand pollinated. None was pure sweet or 

 pure dent. Thirteen showed earlier ripening than the others and were 

 smaller in size. There seemed to be a larger proportion of sweet kernels 

 on these ears. The stalks on which they grew were also earlier maturing 

 and smaller in stature. A count of 2,000 kernels showed .322 white, 1.165 

 yellow, and 51.3 sweet. The sweet being recessive, the proportion agrees 

 fairly well with Mendel's Law. 



d^ Speckled, male ; Reid's Yellow Dent, female. 



Sixteen ears were i)ollinated. Four were pure speckled, twelve were 

 not speckled. Most of those not speckled were pure red, and a few (3) 

 were pure yellow. This also seems to be Mendelian. 



d^ Reid's Yellow Dent, male ; Boone County White, female. 



The record of the number of ears pollenized has been lost or mislaid, 

 hut ears showed the same mixture of kernels as the reciprocal cross, d'. 

 There wei-e no pure ears. In 2,000 ivornels there were 480 pure white, 1.300 

 mixed, and 208 pure yellow — a close rcsemlilance to the results in d\ 



Various selections wvvc made frdin tlu^ almvc crossi'S for 1910 jilant- 

 ing. but the data are not in readiness to report at this time.
