State that all were typical of the hairy Mexican type, ranging from 150 to 

 210 cm. in height. The notes recorded for the 1908 plant used in making 

 the hybrid state that it was typical of the variety except for a general 

 shortening of the intemodes. It was 105 cm. high, had three tassel 

 branches, four nodes above the ear, and the fifth leaf from the top 

 measured 83 by 14 cm. 



Sixteen first-generation plants were grown in 1909. Three pure-seed 

 ears that provided seed for the second generation are designated as No. 

 1,2, and 3. Four plants entered into the parentage of these three ears. 

 No. I and 2 were reciprocals. No. i resulted from pollinating plant 225 

 by plant 226. No. 2 by pollinating plant 226 by plant 225. No. 3 was 

 the result of pollinating plant 262 by plant 263. The ears on all three of 

 the first-generation plants that produced ears 1,2, and 3 showed the usual 

 mixture of waxy and horny seeds that result from crossing the Waxy 

 Chinese and a corneous or homy variety. The notes taken on the four 

 first-generation plants are presented in Table I.

The final planting was made in 191 4. The remnant of seed from the 

 original hybrid ear was planted and furnished 31 first-generation plants. 

 Six rows of approximately 30 plants each were secured of second-gen- 

 eration plants, one row from waxy, and one from the horny seeds of each 

 of the first-generation ears. 



The means of the characters measured are given in Table II, and the 

 coefficients of variation in Table III.
