HYBRID DH 1, KANSAS DENT BY CHINESE. 



Female iMrent. — A white dent developed by Mr. Elam Bartholo- 

 mew, of Stockton, Kans. The variety has never been closely bred, 

 but has been grown continuously^ for a number of years and kept up 

 by selection of ears. No abnormalities. Average height, 7 feet 11 

 inches. The 29 plants grown produced 26 ears and 4 nubbins^ 

 weighing 28.6 pounds. 



Male 'parent. — A vari^y of corn from China, \vith wa^xy endo- 

 sperm, leaf blades borne on one side of the stalk, and silks pro- 

 duced in the angle of the leaf blades.** 



The parent plant was grown from white seed separated from the 

 imported mixture and had the erect monostichous leaf blades that 

 characterize this variety. The second-year plants fi'om American- 

 grown seed showed these characteristics in a much less marked 

 degree than those grown from imported seed. No abnormalities. 

 Average height, 4 feet 7 inches. The 32 plants grown produced 46 

 ears and 9 nubbins, weighing 12.4 pounds. 



Hybrid. — In the early stages the plants resembled the Chinese 

 parent in having erect monostichous leaf blades, but this character 

 was less marked later in the season. The plants remained dark green 

 during a very dry season. The only indication of abnormality was 

 the frequent production of pistillate flowers on the terminal inflor- 

 escences of the suckers. The ears were intermediate in size and 

 appearance and as uniform as those of either parent. Average height, 

 6 feet 9 inches. The 16 plants grown produced 27 ears and 7 nub- 

 bins, weighing 17.5 pounds. 



HYBRID DH 2, CHINESE BY CHIHUAHUA. 



Female parent. — The same as the male parent of hybrid Dhl. 



Male parent. — A starch variety from Chihuahua, Mexico. This 

 variety is peculiar in having the longest leaf sheath at the top of the 

 plant and in having the leaf sheaths covered with fine velvety hairs. 

 No abnormalities. Average height, 8 feet 9 inches. The 14 plants 

 grown produced 13 ears and 2 nubbins, weighing 9.7 pounds. 



o This variety ia more fully described in Bulletin 161 of the Bureau of Plant Indus- 

 try, U. S. Dept. of Agriculture, 1909, entitled "A New Type of Indian Corn from
