AGRICULTURAL EXPERIMENT STATION, 89 



In the first generation the purple-fruited types seem stronger in 

 their power to transmit color to the offspring than do the white- 

 fruited types ; and this law appears to hold whether the purple 

 type is used as the male or as the female parent. In later genera- 

 tions the inherent strength of the white-fruited types appears 

 more strongly than in the first; for in the third generation, after 

 the purple type had twice entered the cross, the effect of the 

 original white parent in imparting color to the fruits was more 

 marked than in the first generation. 



In all cases the white- fruited types appear stronger in the power 

 to transmit form and productiveness. 



Summary. 



1. With careful treatment the egg plant may be success- 

 fully grown in Maine. The most important requisites of 

 success are : Early sowing ; vigorous plants ; late transplant- 

 ing to the field; warm, rich soil; thorough cultivation; con- 

 stant watchfulness for the potato beetle. 



2. The best varieties for this latitude are Early Dwarf 

 Purple, Early Long Purple, Long White, and possibly Black 

 Pekin. Other large varieties are too late. 



3. The chief advantage derived from the crossing of the 

 dififerent races of egg fruits appears to be in the increased 

 vigor and productiveness of the offspring. No valuable 

 market sorts have as yet been developed.
