1. Last spring a total of 1203 first generation selfed ears were examined for deficient kernels. Out of this lot 84 ears were found which appeared to be segregating for deficient kernels, This means that on the average 6.99% of all plants selfed in the eighteen Southern varieties were heterozygous for some deficient kernel character. Chi-square applied to these data proved definitely that these varieties do not have the same gene frequency for deficient kernels. Indian Chief has significantly fewer heterozygous plants (O.7%), Mathewson's Golden Prolific and Wood's Golden Prolific approached significance in having fewer than average heterozygous plants. Golden Queen (20.0%) and Biggs' Two Ear (10.5%) have significantly more heterozygous plants than the average of all varieties.
