Some Experiments by I^uther Burbank 



To get variation in any one direction is to 

 open the door to anything else. Hybridizing the 

 Japanese quince with the common quince, we 

 have large-leaved seedlings which look quite 

 different from the parent (common quince). The 

 final result is a seedling looking like the Japanese 

 quince, without the power of continued growth 

 (too wide a cross to blend permanently or pro- 

 fitably). 



Some of the black raspberries when hybridized 

 with some of the blackberries usually die when 

 the time comes to bear fruit. Many h3^brids 

 perish under the stress of reproduction. The 

 Amaryllis vittata is now eight to eleven inches 

 across, being nearly four times as broad as before 

 the work of selection for size was begun, and 

 with vigor and freedom of growth and bloom 

 amazingly increased. On a strip of poor land it 

 grows very small, with narrow leaves and slender 

 flowers, but on the same poor land some of the 

 hybrid variants grow very large and pay no atten- 

 tion to the soil. A variant of Ainpelopsis quinquefolia
