Marketmore 76 - Collaborative Slicing Cucumber - Organic


Marketmore 76 - Collaborative Slicing Cucumber - Organic

Cucumis sativus
(63 days) Open-pollinated. Dr. Henry Munger’s classic cucumber for the ages, long the leading slicing variety in the Northeast. We still sell nearly 4,000 packets per year, making it our top-selling cuke! Dark green 8–8½" fruits show good uniformity. Vines vigorous throughout the season. Resistant to to CMV, DM, PM, and scab.

As multinationals work to dominate the market with their seed consolidations, a few small like-minded seed companies are cooperating to offer all our customers an alternative. By pooling our orders for organic Marketmore 76, we were able to offer a substantial contract to a single seed grower. We hope the result is better-quality seed and a fair price for everyone. This has been a long time coming and may be a sustainable model for the future of the seed trade. This is now a Supplier Code !

Update: As sometimes happens in life and growing cucumbers, the seeds we planted in spring did not bear as we had hoped come fall. Can you relate? The bad news is we have less Marketmore 76 Slicing Cucumber OG from our collective contract to offer than we had hoped for, hence only A sizes will be available. The good news is we have plenty from our usual sources (see Marketmore 76 - Organic) to supply everyone’s gardens this year. What about our grower? Our collective contract included a clause where we all shared risk with our grower and guaranteed them a minimum compensation regardless of outcome. We aim to treat our growers as partners and take the long view. Thank you for sharing in this collective journey of seed stewardship.

Additional Information


  • About 30 seeds/g; about 900 seeds/oz; variations noted.
  • Days to maturity are from emergence after direct seeding. From transplant, subtract 20 days.

Culture: May be started indoors for early production, or direct-seeded when soil has warmed. Minimum germination soil temperature 65°, optimal range 65–95°. Very tender, will not survive frost. Direct seed 3" apart thinning to 1' apart in rows 4–6' apart or 6 per mound in hills 4' apart thinning to 3 best plants. For transplants: once seedlings have 1–2 true leaves, about 3 weeks old, plant 1' apart in rows 4–6' apart. Cucumbers require good fertility and regular rain or irrigation for abundant yields. Without adequate water, fruits will be misshapen and bitter. Pick cukes frequently for best production, or else the plants shut down. Make sure to remove blimps to the compost pile.

Combat striped cucumber beetles by handpicking early AM when the dew makes them sluggish, or use floating row covers, removing when cukes flower. Cucumber beetles are the vector for BW.

Using compost in conjunction with row covers (rather than either alone) increased cucumber yields at the University of Michigan.

Parthenocarpic varieties can set fruit without being pollinated, an advantage in cold cloudy summers. Gynoecious varieties produce almost exclusively female flowers for uniformity and high yields.

Saving Seed: Saving cucumber seed is easy! Take that big yellow cuke that got away and save it for seed. Scoop out the guts of overripe fruit and ferment it in an uncovered container for a few days. A moldy gross cap to the slurry means the seeds are ready to rinse and dry. To ensure true-to-type seed, grow only one open-pollinated variety per season.
