Competitive Ability of Slash Pine Analyzed by Genotype X Environment Stability Method

Early genetic gains in growth rate may be offset by differential competitive ability when progeny test plantations close. Few tests are old enough, but one by Derr and Dell (1960) in a 22-year-old geographics lash pine (Pinus elliottii Engelm.) seed source plantation illustrates what may happen. There variation in diameter among sources was inversely correlated with 10-year survival. One can conclude that volume gains were reduced by stagnation of diameter growth caused by competition.
