Southern Highbush Blueberries: An Analysis of the Blue Ridge Generation and Its Siblings

The world of blueberries is full of interesting varieties, each offering a unique story. In this installment, we will look into the "archives" of breeding and introduce an important, though now partially outdated, generation of Southern Highbush blueberries from the late 1980s and early 1990s.

"Analyzing older varieties reveals the typical compromises breeders faced in the past and shows how far we have come in terms of quality."

We present four important representatives of this era: Blue Ridge, Cape Fear, Cooper, and Gulfcoast.

The Duo from North Carolina: Flavor vs. Yield

These two sister varieties were bred for regions with medium chill requirements (500-600 hours) and represent a classic breeding compromise.

1. Blue Ridge

A variety focused on flavor quality, adapted to the conditions of the mid-southern USA.

Variety Profile: Blue Ridge

  • Origin: 'Patriot' x US 74 (NCSU & USDA, 1990)
  • Fruit: Medium to large, firm, with an excellent, distinctly tart flavor.
  • Growth: Vigorous and very upright. Ripens in mid-season.
  • Advantages: A unique flavor for lovers of less sweet blueberries.
  • Disadvantages: A problematic picking scar that tears and reduces shelf life. Susceptible to some diseases.

2. Cape Fear

The sister variety of Blue Ridge, focused primarily on high production.

Variety Profile: Cape Fear

  • Origin: US 75 x 'Patriot' (NCSU & USDA, 1990)
  • Fruit: Very large, firm, with a good scar, but only average flavor.
  • Growth: Very vigorous, highly productive. Ripens in the mid-early season.
  • Advantages: Extraordinarily high yield and excellent resistance to stem blight.
  • Disadvantages: Only average flavor and susceptibility to stem canker.

The Duo from the USDA: Compromises for Warmer Regions

These two varieties were intended for the warmer regions of the Gulf Coast but also struggled with compromises.

3. Cooper

A relatively average but reliable variety whose use was limited by higher chill requirements.

Variety Profile: Cooper

  • Origin: G-180 x US75 (USDA, 1987)
  • Fruit: Average size, firmness, and flavor—no outstanding strengths, but no major flaws either.
  • Growth: Medium vigor and productivity. Flowers slightly later.
  • Advantages: Slightly later flowering, which can help avoid frosts.
  • Disadvantages: Higher chill requirement, making it unsuitable for the warmest regions.

4. Gulfcoast

The sister variety of Cooper, which had a crucial commercial flaw but found an unexpected application.

Variety Profile: Gulfcoast

  • Origin: G-180 x US75 (USDA, 1987)
  • Fruit: Average, with one major flaw—a wet picking scar that spoils quickly.
  • Growth: Medium vigor. Flowers earlier than Cooper, making it more susceptible to frost.
  • Advantages: The sole reason for its use—its flowering time perfectly matches the key variety 'Sharpblue', for which it serves as an effective pollinator.
  • Disadvantages: The poor quality picking scar disqualifies it for the fresh fruit market.

Flavor vs. Practicality

Variety Flavor Quality Yield Scar Quality
Blue Ridge Excellent Good Poor
Cape Fear Average Excellent Good
Cooper Average Average Good
Gulfcoast Average Average Poor
