Inheritance of Branching and Crown Characteristics in Slash Pine

This study is concerned with the crown, the photosynthetic surface of the tree; specifically the slash pine tree. Slash pine crowns come in many shapes--long and narrow to short and broad--with short slim branches to long thick branches and with branch angles ranging from a ramicorm condition to 90 degrees. Occasionally the tree with a perfect crown is found, but one with a perfect crown, near perfect bole form, and outstanding growth rate is very rare. This latter type is in a class all its own, a jewel to the tree breeder.
