Testing Slash Pine for Rust Resistance

Key Points

• Resistance to Cronartium fusiforme is inherited in slash pine progeny from nursery tests, indicating genetic potential.
• Heritability estimates from both open- and control-pollinated progenies of Pinus elliottii suggest viable breeding methods.
• Results highlight potential for developing rust-resistant strains through selective breeding techniques.
• Understanding the genetic basis of resistance may support future forest management and conservation efforts.
