Seed Yield and Nursery Performance of Self-Pollinated Slash Pines
Inbreeding does not appear to be a practical way of improving most characters of slash pine (Pinus elliottii var. elliottii Engelm.). Among 35 trees, 80 percent produced less than one seedling per self-pollinated flower. Per collected cone, self-pollination yielded 10 percent as many seedlings as wind pollination. The tallest progenies from wind-pollinations were from parents that had the tallest selfed progenies. Because their height distributions overlap, selfs cannot be effectively rogued from crosses.
