22 VALUE OF FIKST-GENERATION HYBRIDS IN CORN. 



Abnormalities will be briefly noted as a possible indication of the 

 violence of the cross. 



HYBRID AH 3, MARYLAND DENT BY HOPI. 



Female parent. — An imselected white dent grown in Maryland. 

 The particular plant used as the female parent was grown from the 

 seed of a red ear. This proved to be the most prolific of the uncrossed 

 strains; perhaps on account of its being the only locally grown variety 

 in the experiment. No abnormalities were discovered in any part 

 of the plant or in the* ears. Average height, 6 feet 10 inches. The 

 16 plants grown produced 21 ears and 2 nubbins, weighing 19 

 pounds. 



Male parent. — A variety grown by the Hopi Indians of Arizona- 

 The most striking characteristics of the type are the very large male 

 spikelets and enormous ear stalks. The color of the particular ear 

 used in making the cross was a slatv blue. No abnormalities 

 appeared in the plants grown in this experiment, though in Kansas 

 this strain produced a number of ears with inverted grains, the 

 embryo on the lower side, toward the base of the ear, and also a 

 number of grains with double germs. Average height, 8 feet 10 

 inches. The 27 plants grown produced 21 ears and 2 nubbins, weigh- 

 ing 20 pounds. 



Hybrid. — In spite of the fact that both of the parents yield pollen 

 very abundantly, 6 of the 16 h3^brid plants failed to produce pollen. 

 No other abnormalities were observed. The plants were rather 

 diverse, some resembling one parent and some the other. The ears, 

 however, were as imiform as those of either parent and partook of 

 the characters of both. Average height, 7 feet. The 16 plants 

 grown produced 21 ears and 2 nubbins, weighing 20.1 pounds." 



HYBRID AH 4, TUSCARORA BY CINQUANTINO. 



Female parent. — An 8-rowed soft variety, grown by the Tuscarora 

 Indians of New York. The variety is early and suckers profusely, 

 many of the suckers terminating in ears. Average height, 5 feet 8 

 inches. The 16 plants grown produced 14 ears and 10 nubbins, 

 weighing 8.5 pounds. 



Male parent. — A variety imported from Hungary under the name 

 Pignoletto. A very small seeded, many-rowed type that would be 

 classed as a pop, though unlike any of the American varieties of pop 

 corn. This class of corn is known to the trade as "Cinquantino." 

 The variety is small, without suckers, and very early. No abnor- 



o The yields of the hybrids and the parent varieties, reduced to pounds per plant, 

 are brought together for comparison in Table IV, p. 29.
