THE TOMATO 163 



The cross was made reciprocally, pollen from 

 each plant being used to fertilize the stigma of 

 the other. 



The fertilization was effected without difficulty 

 and an abundant supply of seed was produced. 

 The hybrids that grew in the next generation 

 were many of them pretty clearly intermediate 

 in form and appearance between the parents. 

 But some of them were almost ludicrous in 

 appearance. They took on twisted and con- 

 torted forms, and in particular their leaves were 

 curled and twisted into fantastic shapes. 



As to fruit, some of the plants produced long 

 clusters with tomatoes much larger than cher- 

 ries ; others furnished small fruit like that of one 

 of the parents. And in some cases a plant that 

 had retained the short stocky tree form of the 

 tree tomato bore clusters of small tomatoes in 

 bunches similar to those of the other parent. 



The foliage varied astonishingly between the 

 two types. In some there was an exact compro- 

 mise that was very curious. The dark, blistered 

 leaves of the tree tomato, combined with the long, 

 slender leaves of the currant tomato, produced a 

 most interesting effect. Other specimens showed 

 every possible gradation between the parent 

 forms. Here, then, was a case in which there 

 was no conspicuous dominance of one parent or
