Ear No. 1131 had 22.9 per cent waxy seeds, while self-pollinated 
ears secured from the male and female parents had 24.2 and 23.3 
per cent waxy, respectively, as shown by the following diagram: 
Pedigree No. 1132 (Table I), 23.34+1.2 per cent waxy

Hepad Dh 334/004 
Self. Pedigree No. 1117 (Table I), 24.241.2 per cent waxy. 
As can be seen from the diagram, neither of the parents of ear 
No. 1131 deviated from the expected 25 per cent by a larger per- 
centage than could be ascribed to chance, although both parents, as 
well as ear No. 1131, were below the expected percentage. 
As ear No. 1131 was all colored, there were only two classes’ of 
seeds, horny and waxy. These were planted separately and self- 
fertilized by tubing (6). The waxy seeds when self-pollinated 
resulted in all waxy ears. Such ears, therefore, were not tabulated. 
HORNY. 
Four ears that were the result of self-pollinating horny plants 
were secured from the horny group. These ears are shown in 
Table IX. 
Two ears were above and two below the expected 25 per cent of 
waxy seeds. The deviation on all of these ears could be ascribed to 
chance. The four ears had a total of 1,055 seeds, with 24.3 per cent 
waxy, the deviation of 0.7 per cent being 0.74 times the probable error.

There are two remaining ears that represent crosses between the 
two hybrids Dh 234 and Dh 237. These ears are Nos. 1110 and 1134 
(Table I), as shown by the following diagram:
