Abstract

At age 10, shortleaf x slash pine hybrids performed relatively poorly when compared with loblolly pine in 10 plantings throughout the southern pine region. The hybrids excelled only in resistance to fusiform rust. Over all plantings, loblolly averaged about 5 feet taller than the hybrids and had almost twice as much volume. The hybrids' rust resistance may make it a valuable source of germ plasm for breeding programs aimed at producing varieties of slash pine with a broad genetic base for resistance.
