pines. Agriculture Hand- 

 book 587, on pollen man- 

 agement, covers the collec- 

 tion, processing, storage, 

 and use of pollen from 

 superior trees and provides 

 a synthesis of research and 

 practical experience as to 

 the best methods and 

 equipment for handling tree 

 pollen of southern pines 



and hardwoods (Franklin

 and John Talbert summa- 

 rized many years of research 

 on the genetics of southern 

 pines in their major book

 provement."
