LUTHER BURBANK 



which produced regularly four and five times as 

 much as the average production of the parent 

 form. 



Of course, this quality of productivity was 

 combined with the various other qualities and was 

 manifested in the perfected pea that was delivered 

 along with the letter just quoted. 



But there were other qualities which obviously 

 could not enter into the combination, because of 

 variation in exactly the opposite direction from 

 the one in which we were developing the little 

 canning pea. Thus, for example, one variety 

 instead of having small peas had exceptionally 

 large ones. Another variety produced lozenge- 

 shaped peas. These seemed to be unusually sweet, 

 and as they were also among the most productive, 

 I made two strains of this selection alone. One of 

 these is a very large lozenge-shaped pea, circular, 

 and indented on the flattened sides. 



Both are practically fixed, coming true to type 

 from seed. 



In point of fact, by having ditf erent ideals and 

 bearing them in mind all along, I developed four 

 strains of new varieties that the canners were glad 

 to purchase, in addition to the one that they had 

 specifically ordered. And all this was done, as 

 just noted, by selection, without the aid of hybrid- 

 izing experiments.
