Report op the Work in Corn Pollination, IV 



By M. L. Fisher. 



A series of studies in com pollination was begun in IWS. Tlie results 

 of these experiments have been reported from time to time. The present 

 report will deal with the Sweet-Reid's Yellow Dent cross. 



In 1011 the two types wliich arose from this cross were planted, but 

 conditions were such that only enough for seed was obtained. There was 

 no chance to determine the quality. In 1912 the two types were again 

 planted. Only a small area of ground was available and it was necessary 

 to resort to self-pollination again. 



The germination from both types proved good and the plants grew 

 vigorously. The light-colored type was the more vigorous of the two and 

 produced a larger pro])ortion of ears. 



^Vhen the ears were in proper condition samples were taken for 

 cooking and testing as to quality. The light colored type had large ears, 

 white in color. Upon cooking the flavor was found to be excellent, being 

 very sweet. The sweet flavor combined with a long grain makes this a 

 very desirable type. The cooking test showed it to be superior to the corn 

 bought on the market in West Lafayette. 



The yellow type had a medium sized ear. creamy white in color and 

 when cooked had also an excellent, sweet flavor. The flavor was consid- 

 ered not quite so good as that of the light colored type. 



At maturity the light colored type showed itself quite true to type, 

 having whitish Ivernels, red cobs, and large size. There were few yellow 

 dent kernels, probably no more than due to cross-pollination from adjoin- 

 ing plats. 



The yellowisli type had smaller ears, mostly white cobs, yellowish 

 kernels, and a larger proportion of yellow dent kernels than the other 

 type. The yellowish type does not have the depth of kernel that the whit- 

 ish type possesses. 



The crop season of 1913 will be the final test for this experiment. 

 The result of this season will determine whether the new types are worthy 

 of extensive propagation.
