Abstract
Homozygous trees will never be the desired ultimate step in a forest tree improvement program. However, they will serve many purposes in forest genetics research: (1) in the detection of genetic markers; (2) in the isolation of traits under simple genetic control for the study of growth and differentiation phenomena; (3) as a tool as well as reference material in the study of breeding mechanisms in natural populations; (4) as reference material in a study of the efficiency of different selection schemes; and (5) in the study of sex control mechanisms in dioecious species. Furthermore, homozygous trees could serve as an intermediate step for the production of heterotic intra- and interspecific hybrids.
