 as it does from a layer plant.

BREEDING METHODS 



There has been much indefinite and futile effort in 

 strawberry breeding. Some enthusiastic amateurs have 

 entertained the notion that superior new varieties can 

 be produced simply by growing the seeds of exception- 

 ally large and attractive berries. There is a chance that 

 among thousands of seedlings produced in this haphazard 

 fashion one may be of merit, but usually the result is 

 wholly disappointing. 



Methods of the early breeders. The only way to be 

 absolutely sure of the parentage of seedlings is to pollinate 

 the blossoms by hand. It is possible that berries not
