Apple VA 38

Advanced Genetic Selection from Washington State University

The WA 38 cultivar, widely recognized in the global market under the name Cosmic Crisp, represents a milestone in pomology developed by Washington State University. This winter apple variety was engineered to address the industrial need for fruit that balances extended shelf life with premium organoleptic profiles, backed by robust field performance.

Tree Physiology and Canopy Management

The WA 38 tree exhibits vigorous growth and a spreading canopy. From a technical standpoint, this architecture allows for efficient canopy management and optimal light penetration, which is essential for uniform fruit coloration. A key differentiator for WA 38 is its inherent resistance to apple scab (Venturia inaequalis). This biological trait significantly reduces the dependency on chemical fungicides, contributing to a more sustainable production model and lowering operational input costs.

Fruit Technical Specifications

• Dimensions: The fruit weight averages 150–200 grams, meeting the commercial size requirements for the premium fresh-market segment.
• Morphology: Characterized by a slightly oblate (flattened) shape, which is highly advantageous for automated sorting and packing line efficiency.
• Coloration and Texture: The fruit features a vibrant red blush with a distinct marbled pattern. The flesh is cream to yellowish, offering a crisp, dense texture.
• Organoleptic Value: Rated at 5.0 in sensory evaluations, the flavor profile is a primary driver for its market popularity.
• Post-Harvest Longevity: The cultivar maintains excellent quality for 3–4 months in standard cold storage, facilitating extended market availability throughout the winter season.

WA 38 serves as a benchmark for modern breeding, providing orchardists with a variety that resists common pathogens while consistently delivering high-quality fruit that meets end-consumer expectations.
