Abstract
Hybrids between shortleaf and slash pine were made by controlled pollination with each species used alternatively as the female parent. Hybrids with shortleaf as the female parent survived planting better than those with slash as the female parent. In all other respects-height, d.b.h., and resistance to diseases and insects-the species used as female parent did not affect resulting progeny.
