Abstract

Backcross breeding uses two crosses to create genotypes with improved traits. The first cross establishes an F1 population, which is then used as the female parent in a set of second crosses. The male parent of the second cross is often a genotype well-adapted to local environments. A currently investigated backcross population is the result of crosses between Populus deltoides x P. trichocarpa females and P. deltoides males. Therefore, recombination may result in BC1 genotypes ranging from almost 50% P. trichocarpa to nearly 100% P. deltoides. The goal of this breeding scheme is to incorporate rooting ability of P. trichocarpa into regional adaptability of P. deltoides.
