Inbreeding depression is important in the evolution of plant populations and mating systems. Previous studies have suggested that early-acting inbreeding depression in plants is primarily due to lethal alleles and possibly epistatic interactions. Recent advances in molecular markers now make genetic mapping a powerful tool to study the genetic architecture of inbreeding depression. We describe a genome-wide evaluation of embryonic viability loci in a selfed family of loblolly pine (Pinus taeda L.), using data from AFLP markers from an essentially complete genome map.
Pruning may be carried out for several reasons, such as improving access (prune break or edge trees only); fire protection (prune a strip along vulnerable boundaries); and for 'clearwood' (prune selected best trees). Pruning can be combined with early thinning to shorten the rotation and thus provide an earlier profit return.
