Inheritance of Stem and Branch Characters in Slash Pine and Relation to Gum Yield

The original tree improvement program at Olustee, Florida was confined to selection and breeding for increased gum yield. Recently the program has been modified to include combining gum yield with other desirable traits (Squillace, 1965). In accordance with the revised objective, the present study was designed to determine inheritance of number of crooks per foot, degree of crook, size of branches, and crown width ratio and to determine relationships of these traits with gum yield.
