The work reported in this paper was done at the Nebraska Agricultural Experiment Station in connection with the regular corn breeding work during 1922, 1923, and 1924.

The subject of Mendelian inheritance is one that has occupied a very prominent place in the field of science over a long period of years. The plant that has perhaps attracted the most attention is corn (Zea mays).

Owing to the large number of varieties and the high number of chromosomes (10 pairs Sharp) corn is well adapted for genetical work, and especially for work on the Mendelian ratios.

It was the object of this work to get actual field counts of certain characters, which appeared as though they perhaps might be unit factors.

Owing to the large number of factors already determined (nearly 100) it is doubtful if anything new has been found in this work.

No attempt has been made to go into a great amount of detail, but great care was taken in the field to get the results as nearly correct as possible. There has been a very extensive amount of technical work carried on along the line of Medelian inheritance in corn, which will be treated more fully in the historical section of this paper.

This paper is composed of three parts, 1 Historical, 2 Experimental, 3 Observations and Conclusions.
