A NEW SEEIES OF HYBRIDS BETWEEN DIVERSE TYPES. 27 



Hybrid. — Ears very irregular. One plant produced 2 ears, both 

 of which were interrupted. In many others the ears exceeded the 

 husks. The 16 plants grown produced 8 ears and 8 nubbms, weighing 

 5.25 pounds. 



HYBRID MH 13, QUARENTANO BY BROWNSVILLE. 



Female 'parent. — A drought-resistant variety from Chiapas, Mexico. 

 Many of the plants of this variety have very wide leaf sheaths that 

 are closely wrapped around the weak stalk and are the chief support 

 of the upper part of the plant. Average height, 7 feet 6 inches. The 

 16 plants grown produced 8 ears and 7 nubbms, w^eighing 4.3 pounds. 



Male parent. — The same as the female parent of Dh6. 



Hyhrid. — Plants and ears very diverse, w^ithout the peculiarities of 

 the female parent. Nine of the plants produced ears exceedmg the 

 husks. In three cases the ears were interrupted. The inner husks 

 w^ere crumpled at the base of the ear, a not uncommon condition with 

 thick-husked varieties. Average height, 11 feet 5 inches. This is 

 one of the two cases where the yield of the hybrid was below the 

 average of the parents. With such disparity between the yields of 

 the two parents this may mean that the Iwbrid more nearly resem- 

 bled the lower yielding parent. The 16 plants grown produced 11 

 ■ears and 7 nubbins, weighmg 7.6 pounds. 



HYBRID MH 15, HUAMAMANTLA BY HAIRY MEXICAN. 



Female parent. — A drought-resistant variety with shoe-peg grains, 

 from Mexico. A variety of the hairy Mexican series, though not a 

 pronounced type. The tassels have a few very long primary branches. 

 The season the cross was made this variety had 50 per cent of the 

 ears interrupted. Plants grown from the same original seed in the 

 season of 1909 had no interrupted ears. Average height, 8 feet. The 

 1.3 plants gro^vTi produced 4 ears and 7 nubbms, w^eighing 5.2 pounds. 



Male parent. — A pronounced type of the hairy Mexican series, with 

 superficial roots, hairy leaf sheaths, and usually unbranched tassels. 

 The poorly protected ears usually decay in the moist fall weather. 

 Average height, 7 feet 11 inches. The 16 plants grown produced 5 

 ears and 4 nubbins, weighing 2.8 pounds. 



Hyhrid. — Plants irregular, exhibiting nearly the full range of both 

 parents. The stalks were rather weak; the tassels with from 3 to 7 

 branches. One ear was produced with a staminate portion at the tip. 

 Average height, 9 feet 1 inch. The 15 plants grown produced 7 ears 

 and 9 nubbins, weighing 4.6 pounds.
