Proven Performance for a Wide Range of Planting Goals

ArborGen’s OP and OP Pro pine seedlings are developed from carefully selected parent trees backed by decades of breeding, field testing, and regional evaluation.

In open pollination, the female parent tree is known and selected for desirable performance traits, while pollination occurs naturally within a managed orchard environment. The result is genetically improved seedlings designed to deliver dependable growth, adaptability, and long-term value across a variety of planting conditions and management strategies.

For customers seeking reliable performance with flexible investment options, OP pine seedlings provide a proven foundation for long-term stand success.

OP Product Categories

ArborGen’s OP product categories help landowners and foresters compare seedlings based on performance potential, stand quality, and management goals. Backed by decades of breeding, field testing, and regional evaluation, OP and OP Pro seedlings provide dependable field performance across a wide range of planting conditions.

AG Scores also help customers compare products more confidently based on their planting priorities and long-term objectives.

Open Pollinated

Best For Reliable Performance And Balanced Return

An industry standard with two to four generations of genetic improvement, OP pine seedlings provide dependable growth and solid returns. They offer a strong foundation of volume gain, disease resistance, and stem form, producing good-quality standard trees that yield a mix of solid wood, pulp, and paper products.

Open Pollinated Pro

Best For Improving Productivity Without Added Cost

A step up in trait performance such as volume, disease resistance, and stem form, OP Pro pine seedlings represent the top 4% of open-pollinated families for combined performance. Naturally pollinated yet enhanced for consistency, these seedlings outperform traditional OP stock and are well-suited for applications where reliability and moderate gains are desired, including sawtimber stands with multiple thinnings.

What is the AG Score?

The ArborGen Score, or AG Score, is an index that combines each family’s performance for productivity, rust resistance, stem straightness, and forking into a single number.

Frequently Asked Questions

Choosing the right genetics is an important long-term decision, and it’s natural to have questions about performance, value, site suitability, and management goals. Here are answers to some of the most common questions landowners and forestry professionals ask when evaluating OP pine seedlings.

OP Pro seedlings represent higher-performing open-pollinated genetics selected for improved growth, stand quality, and consistency compared to standard OP products.

Yes. ArborGen OP seedlings are genetically improved through decades of breeding, testing, and orchard selection designed to enhance field performance, adaptability, and stand quality compared to unimproved seedlings.

OP seedlings are produced through open pollination, where seed comes from a known, carefully selected mother tree chosen for desirable traits like growth, stem quality, root structure, and disease resistance. Pollination occurs naturally within managed seed orchards, blending those superior genetics with the hardiness and adaptability long associated with southern pine species like loblolly and slash pine.

Across more than 1,000 acres of seed orchards from Georgia to Texas, ArborGen produces regionally adapted seed sourced from orchard trees that have been extensively tested through decades of genetic field trials. With more than 35 years of continuous breeding and improvement, these genetics continue to evolve to support stronger stand performance across a wide range of planting conditions.

The best species depends on your region, soil conditions, management goals, and planting strategy. Loblolly Pine is commonly selected for productivity and versatility, while Slash and Virginia Pine may be better suited for specific site conditions or objectives.

Yes. OP seedlings continue to provide dependable growth and stand performance across many timber management strategies. Customers focused on maximizing long-term productivity and sawtimber potential may also consider MCP® products depending on their goals.

Yes. ArborGen evaluates OP families across multiple growing environments to help ensure strong regional performance and adaptability throughout the Southeast.
