Description

(Cucumis sativus). Marketmore ‘76 is a name synonymous with vigor and productivity. Marketmore ‘76 is possibly one of the most recognizable heirlooms, and rightfully so. Decades after its initial introduction, this delicious, refreshing cuke still boasts impressive disease and pest resistance. Fruit averages 8-9 inches long, perfect for slicing. Dark green with thick protective skin, a perfect choice for market gardening as the rugged little fruit stands up well to shipping but still have the high quality of flavor and texture that grocery store cukes simply can’t match! 

The original Marketmore cucumber was developed at Cornell University in 1968 by Dr. Henry Munger. It was hailed as a breeding breakthrough for cucumbers. For 30 years Dr. Munger perfected the Marketmore (and many other incredible vegetable varieties). In 1976 he released a particularly vigorous open-pollinated strain of Marketmore, and it remains a favorite of home and market gardeners alike! We are grateful to Dr. Munger, who in his 60 years of breeding at Cornell championed the idea of bringing more densely nutritious vegetables to the forefront of the diet in order to promote health.

Growing Tips: Marketmore 76 cucumbers produce straight, uniform fruits with deep green skin and a crisp, mild interior. Known for high resistance to many common cucumber diseases, this open-pollinated variety thrives in warm, sunny gardens. Trellising improves air circulation, reduces pests, and keeps fruits clean. Consistent watering and timely harvesting maximize yield and fruit quality. Some afternoon shade is beneficial in the hottest summer weather.

When to Grow

Direct sow Marketmore 76 cucumber seeds outdoors after your last frost date, once soil temperatures have reached 70°F or warmer. In cooler regions, start seeds indoors 3–4 weeks before transplanting. These cucumbers thrive in raised beds or open ground with full sun and warm soil.

How to Sow and Plant

Plant seeds 1/2 inch deep in fertile, well-drained soil rich in organic matter. Space plants 12 to 18 inches apart in rows or hills. Install a trellis at planting time to encourage upright growth. Water thoroughly after sowing and keep the soil evenly moist to support strong, healthy germination and early development.

How to Grow

Water deeply at the base of the plant, avoiding wetting the foliage. Apply mulch to retain soil moisture and deter weeds. Fertilize with an organic, balanced formula every 2–3 weeks. Trellising allows for better airflow, straighter fruits, and easier harvesting. Pick fruits at 6–9 inches long for best texture and to prolong harvest.

How to Save Seeds

  • Select disease-free plants for seed saving.
  • Allow fruits to fully ripen on the vine (they will turn yellow or orange).
  • Scoop out seeds and pulp into a jar or bowl with water.
  • Ferment at room temperature for 2–3 days, stirring daily.
  • Rinse seeds thoroughly and dry on a screen or paper towel for 1–2 weeks.
  • Store in a cool, dry place in a labeled and dated airtight container.
