In 1941 one plant from a very uniform appearing ear-row of inbred Kys produced a self-pollinated ear segregating approximately 3:1 for lemon yellow and ivory colored kernels. When planted in a germinating bed the yellow seeds produced all green seedlings and the white seeds produced only albinos. In 1942 a row was grown from the yellow segregates and each plant self-pollinated. Of the 20 ears produced, 7 were homozygous yellow and 13 were segregating for yellow and white. Seedlings grown from these segregating ears gave the following totals:


green white
Yellow seeds 3910 3030 14
White seeds 1104 11 785


Ten of the 11 exceptional green seedlings from white seeds were successfully transplanted and grown to maturity. Because of unfavorable conditions only five of the attempted self-pollinations were successful, but in every case both yellow and white kernels were produced. It appears probable that a single gene with a dual effect was involved in the original mutation, and that the aberrant seedling types were due to hetero-fertilization.
