236 NEW JERSEY STATE AGRICULTURAL 



In 1906, a seed classification of this set was made upon the 

 basis of color and included five groups, namely, ( i ) like the 

 male parent and called "Jackson Wonder," (2) "dark red," (3) 

 "lighter red," (4) "mottled red" and (5) "white" like the female 

 parent. The "dark red" (2) is the color most nearly like that 

 present in the seeds of the blend plant, that is, the direct result of 

 the cross. 



The "Jackson Wonder," "dark red" and "lighter red" strains 

 have occurred in all the crosses but the "mottled red" (brick red) 

 has thus far appeared only in the "Henderson," "Willow-Leaf" 

 and "Station Bush" combinations, while the "Burpee" alone has 

 failed to give white-seeded plants. 



For this year's crop, shown in the table below, seed was 

 selected from plants which, in turn, were produced by seed of the 

 same color, thus insuring in all cases where this season's harvest 

 gave true seed, the same color type for three successive genera- 

 tions. 



This indicates in the white-seeded sorts, for example, that no 

 blood of a dark-seeded plant had been introduced through the 

 parent or grandparent.

The average per cent, for all the "Jackson Wonder," "dark 

 red" and "white" types, respectively, is 79.3, 67.6 and 95.1. As 

 indicated by the last column, the largest yield is among the
