AGRICULTURAL EXPERIMENT STATION. 83 



the dark purple became of a dull greenish cast, while the apex 

 became metallic gray with streaks of grayish purple extending 

 towards the base. 



From this first generation, several crosses and selections were 

 made for further study. These were as follows : 



A 1. Given pollen from another flower of same plant. 



A 2. Given pollen from Round White (female parent). 



A 3. Given pollen from Black Pekin (male parent). 



A 4. Same as A. 3. 



A 5. Same as A. 1. 



A 6. Same as A. 1. 



A 7. Same as A 2. 



A 8. Selection, parentage uncertain. 



Of the above selections the fruit was uniformly of the color 

 before described, but varied considerably in size. The general 

 characteristics of the plants were as follows : 



A 1. Of the general habit of Round White, — the pistillate 

 parent — but the upper surface of stems, petioles and veins was 

 purple, showing influence of the male parent. Of the four fruits 

 borne, two were the size of a hen's egg, and two much larger — 6 

 inches long. 



A 2. Similar to the first, but the purplish tinge less marked. 



A 8. Plant strong and vigorous, with upper surface of stems 

 and leaves dark purple. 



A 4. Plant vigorous , leaves much larger than with the first 

 three, many of them being considerably lobed, and all of the 

 pronounced purplish cast of Black Pekin. The fruits, however, 

 were shaped like Round White. 



A 5. Plant of medium size, bright green. Two fruits of 

 medium size — about six inches long — mostly of two shades of 

 purple, with upper surface dark green. Very mature fruit has 

 yellowish cast of Round White. 



A 6. Vei'y similar to A 5. 



A 7. Plant of the general type of the series. Fruits of three 

 distinct forms, one like Round White, a second four inches in 

 diameter and like Black Pekin, the third spherical and very small. 



As an example of variability induced by crossing, this series is 

 one of great interest. There were no immediate effects of pollen,
