COLORED X SELF. 
Fourteen self-pollinated ears were obtained that were expected to 
have 25 per cent white. These ears are also shown in Table XXII, 
columns 10 to 15. Two ears deviated slightly in excess of three times 
the probable error, but the remaining ears were very close approxi- 
mations to the expected 25 per cent. Seven ears were above, six 
below, and one equaled the expected percentage.

SUMMARY OF THE HYBRID DH 237. 
From the progeny of the hybrid Dh 237 there were in all 48 plants 
that produced 64 ears. Of these, 32 ears were below, 28 above, and 4 
equaled the expected percentages. There were only 6 ears that must 
be considered exceptions. While the ratios on these 6 ears can not 
be brought into accord with the other results, the progeny of hybrid 
Dh O37 | 1s eee uniform as compared with the sister hybrid 
Dh 284. 
PROGENY OF THE CROSSES BETWEEN THE TWO HYBRIDS DH 234 
AND DH 237. 
EARS NOS. 1110, 1131, AND 1134. 
Three ears representing crosses between the two hybrids Dh 234 
and Dh 237 were selected for planting. These three ears were all 
colored and therefore do not appear in the second-generation tables. 
The ear numbered 1110 was borne on a plant of the hybrid Dh 234, 
which, when self-pollinated, produced ear No. 1111, the progeny of 
which have been considered on pages 39 to 46.
