numbers that are in excess of the require- 

 ments of theory. In short, the results 

 suggest that the seed parent in both 

 directions of the cross may have a more 

 potent influence than its mate. 



We now pass to a consideration of 

 the fruit characters other than color 

 namely, the weight, length and width. 



Table VI shows that fruits are heavier 

 and larger in the cross with Dandy 

 Dwarf upon Yellow Cherry, than its 

 reciprocal. In other words, the pollen 

 parent is apjjarently the more potent for 

 the fruit characters here under consider- 

 ation. 



The relation of the size of the ]:)lant 

 (standard or dwarf) to the weight, 

 length and width of the fruits is shown 

 below (Table VII). 



Table \'II shows that when the fruits, 

 five each, of all the 252 plants are com- 

 bined, the average weight of those 

 produced by standard plants is much 



fcss than is the average weight of the 

 Iruits borne by the dwarf plants. A 

 similar association obtains with size of 

 fruit, but the differences for length and 

 width are less, namely 8.70% for length 

 and ■i.Hl'c for width. 



The relation of the color of the foliage 

 (green or yellow) to the weight and size 

 of the fruits is shown in Table VIII. 



Table VIII shows that the plants with 

 green foliage produced heavier fruits, 

 than did the plants with yellow foliage, 

 the difference being 3.H7%. In length 

 of fruit the corresponding difference is 

 4.69'^V' , but in width there is no marked 

 difference. 



The relation of the type of leaf (fine 

 and coarse) to the weight and size of 

 the fruits is shown in Table IX. 



Table IX shows that the plants with 

 coarse leaves produced heavier and 

 larger fruits than did the plants with 

 fine leaves. In weight the difference
