INHERITANCE OF WAXY ENDOSPERM IN MAIZE. 3 
on record in the most complete and available form. An effort has 
been made to tabulate the results in such a way that pedigrees can 
be traced readily, and it is hoped that the data may have a value 
apart from the explanations that are suggested or considered in the 
body of the bulletin. 
CROSSES BETWEEN THE ALGERIA AND A CHINESE VARIETY. 
FIRST GENERATION. 
In 1911, pollen of a plant of the white Chinese variety with waxy 
endosperm, was used on a plant of a colored variety of pop corn 
that has been grown under the name Algeria.t| The resulting ear 
was indistinguishable from pure seed ears of the Algeria, both the 
aleurone color and the horny texture of the endosperm of the latter 
showing complete dominance. This hybrid ear received the num- 
ber Dh 227. : 
The same year a cross was made, using the white waxy Chinese 
variety as the female parent and the Aigeria as ‘the male parent. 
This hybrid ear received the designation Dh 234, 
SECOND GENERATION. 
Seeds from Dh 234 and Dh 287 were grown in 1912 and in 1918, 
and 96 hand-pollinated ears were produced. These 96 ears bore four 
classes of seeds: Colored waxy, white waxy, colored horny, and white 
horny. The color of the aleurone is discussed later and may therefore 
be disregarded in analyzing the inheritance of the endosperm texture. 
The numerical results are presented in Table I. — 
1The original seed of this variety was obtained from Dr. Trabut in Algeria by Mr. 
W. T. Swingle. Dr. Trabut has recently informed Mr. Swingle that the variety is not an 
Algerian yariety, having been introduced into Algeria from Morocco. /
