zygous for the color factor & (Table XXXII). These 20 ears had 
a total of 12,394 seeds with a correlation of 0.769+0.006 between 
colored aleurone and horny endosperm. The lowest correlation se- 
cured in any individual ear was 0.697-+-0.35, which is certainly a 
significant correlation. 
The correlation for the combined seeds of these 20 ears was a very 
close approximation of the 0.766 expected on the assumption that the 
correlation is the result of a 3-1-1-3 reduplication in the gametes. 
One ear, No, 1128, has a correlation exceeding the expected 0.766 by 
3.8 times the probable error, but the remaining ears are exceptionally 
close approximations of the 3-1-1-8 coupling, and with 20 ears one 
such deviation is not surprising.

color of self-pollinated and pure-seeded ears of maize having approximately 
25 per cent of the seeds white in the second generation of the hybrid Dh 237.

did not show a correlation between endosperm texture and aleurone 
color and the hybrid Dh 237 with the gametic composition cRA CRM 
did show a correlation, we can assume that the correlation is between 
the color factor (7 and endosperm texture. Additional evidence that 
the correlation is between a factor for color and endosperm texture 
is obtained from the self-pollinated ears of the hybrid Dh 237 that
