CORRELATION IN THE SECOND GENERATION OF THE HYBRID 
DH 237. 
If the correlation is between the color factor C and horny endo- 
sperm, the self-pollinated ears of the hybrid Dh 237 should exhibit 
a correlation between aleurone color and endosperm texture, since 
this hybrid has been assumed to be heterozygous for the factor C. 
From this hybrid 20 ears were obtained that had approximately 25 
per cent of the seeds white, indicating that these plants were homo-
