Abstract

Plantings in Georgia and Florida were established with slash pine seedlings of three genetic types: selections improved for high gum yield (IHGY), selections with improved growth and form (IGF), and commercial stock (CS). Under adverse environmental conditions in Florida, IHGY survived best at age 3, CS next best, and IGF poorest.Survival was more than twice as high in Georgia at age4; it was uniformly high except for IGF seedlings from one nursery. Significantly more fusiform rust was found in CS than in IHGY or IGF stock.IHGY had 44.8 percent more volume than CS at age 10; no 10-year-old IGF were available for comparison.
