(2) produce a superabundant crop of fruit of (3) 

 the largest size, (4) best color, (5) firmest texture, 

 and (6) finest quality; growing in (7) easily 

 gathered clusters on (8) trees of fine shape that 

 are (9) hardy and (10) immune to the attacks of 

 insects, had I not extended my experiments far 

 beyond the narrow limits of hand pollenation, 

 with the aid of my hosts of indispensable helpers, 

 the bees. 



So the biometric computations give fullest sup- 

 port to the practical methods that I have employed 

 for the past forty years. 



Meantime, the results of my experiments — 

 proving the possibility of segregation and reas- 

 sembly of these diverse qualities — give vivid 

 illustrations of the fundamental truth of the 

 theory of unit characters, if these he properly 

 interpreted. 



Good Fruit From Bad Ancestors 



As a further illustration in point, note this 

 curious circumstance: 



I have in various instances used as a parental 

 stock, for purposes of hybridization, a cherry that 

 produced a totally worthless fruit. The object of 

 this selection was to introduce into a developing 

 strain of cherries some good quality — say prolific 

 bearing — that the otherwise worthless cherry 

 showed in high degree.
