Table XV. — Germination record of 11 varieties of corn cross-fertilized with Marlboro 



Prolific pollen. 



An unusual quantity of this seed was planted in each hill and later 

 thinned to the stand desired. When the com came up and started 

 to grow, the vigor of the crossed and of the uncrossed plants was not 

 noticeably different. The productiveness of the female parents in 

 comparison with the first-generation crosses was tested at States- 

 boro, and upon the same farm where the crosses were produced the 

 previous year, but in a different field. The field had been brought 

 into cultivation more recently than those used in 1909, and altliough 

 not rich it was quite uniformly fertile. 



The seed was planted in hills, and two stalks were left to the hill. 

 The stalks stood from 6 to 8 inches apart in the hill. The iirst mem- 

 ber of each hill in a row was from the remnant seed, and the second 

 member of the hill was progeny of the first, which had been cross- 

 poUinated the previous year. 



PLAN OF TESTING PRODUCTIVENESS IN 1910. 



Diagram 2 shows the arrangement of this 1910 planting. The 

 varieties were planted in alphabetical order, and their ears in numer- 

 ical order. As shown in the plan, each hill, for example, of row 1 in 

 section 1 contained two stalks; the first stalk was from original ear 1 

 of Aldrich Perfection, and the second stalk from an ear descending 

 directly from ear 1 of Aldrich Perfection, and which was cross- 

 pollinated in 1909 with pollen from Rodgers White Dent.
