Fusiform Rust Epidemics in Family Mixtures of Susceptible and Resistant Slash and Loblolly Pines
Fusiform rust incidence (% trees infected) was measured through age 5 yr for mixtures of susceptible and resistant slash pine (Pinus elliottii var. elliottii) and loblolly pine (P. taeda) planted in seven potentially high-rust-hazard locations in the Coastal Plain of FL, GA and MS. Four mixtures of six open-pollinated pine families were evaluated: rust-susceptible slash (SS), rust-resistant slash (RS), rust-susceptible loblolly (SL), and rust-resistant loblolly (RL). Few trees were infected through age 2 yr; rust increased in years three to five concomitant with an increase in tree height.
