Wester: Carica Papaya 



would probably be more successful if the flowers were hand-pol- 

 linated with their own pollen than if pollination were accomplished 

 with pollen from flowers differing in structure. It seems quite 

 probable that in a batch of seedlings grown from an individual 

 fruit with small seed-cavity and few seeds - the flowers of course 

 being bisexual — some seedlings would have a greater percentage 

 of flowers that would develop this type of fruit, which would be 

 preferable commercially to fruits with large cavities containing 

 numerous seeds. It is probable that by inbreeding and rigid 

 selection for several generations a variety of papaya bearing all its 

 fruits of this type might be originated, which, the flowers being, 

 self-pollinated, would reproduce itself true to the variety.
