EXPERIMEi^T STATION REPORT. 307 



Assuming that these una bred according to the Mendel ian rule, 

 the nmnber of plants for each combination in a total of sixty-four 

 is appended. At that time no standard coarse-leaved yellow-fruited 

 variety could be found in the market and the work of isolation 

 was begun. According to the law governing dominance the yel- 

 low color of fniit and coarseness of foliage was at once separated 

 by ehosing a standard coarse-leaved yellow-fruited plant. It was 

 necessary to eliminate the dwarf lurking in some of the standard 

 plants, and this was accomplished by breeding several such to 

 themselves and repeating this in the next generation, when a sot of 

 seedlings was obtained that contained no dwarf and the end was 

 reached. 



PALE FOLIAGE IN TOMATOES. 



A very few commercial varieties of tomatoes such as the "Prin- 

 cess" and "Dandy Dwarf" have a pale foliage, suggesting that the 

 plants are sick. Such plants seem in fact as; vigorous as those with 

 the usual dark green color, and in some instances they have ex- 

 ceeded in vitality the normal plants among which they stood. In 

 breeding, this lack of green has acted as a unum in connection with 

 the ordinary color— thus 'the "Yellow Prince" (148) has been 

 crossed upon "Princess" (109), and the pale foliage plants came 

 to liglit in the first generation and in numbers that suggests that 

 it is recessive. This view is corroborated hy the pale plants when 

 bred within their own peculiar type always reproducing the pale 

 plants. 



The above peculiarity is one that does not show itself until the 

 plants are of considerable size, and therefore prohibits their being 

 discarded as seedlings at the time of transplanting to the open. 



It might be possil>le as a matter of technical breeding to pro- 

 duce as many kinds of tomatoes with pale foliage as with ordinarv 

 green leaves, but, possibly, other than as curiosities the labor would 

 not be well expended. 



NOTES UPON HAIEINESS OF STEM. 



The "Currant" tomato differs quite strongly from the ordinary 

 sorts in the comparative absence of the long pointed hairs sO' ob- 

 jectionable in the latter. FromUe hybrid "Currant" and "Dwarf
