Marketmore 86 Slicing Cucumber - Organic


Marketmore 86 Slicing Cucumber - Organic

(56 days) Open-pollinated. White-spined slicer bred by Dr. Henry Munger of Cornell, released in 1986. Each of Munger’s numbered Marketmore creations is a leap forward in yield and disease resistance. Yet he never sacrificed flavor. In our 2018 and 2019 trials, his “86” challenged our singular adoration of Marketmore 76. “86” is 5 days earlier, with a much darker green skin and its 8" length is slightly slimmer. While not of bush-habit, “86” is a less sprawling but leafy plant with high yields equal to “76”. And the crisp clean non-bitter cuke flavor is paired with a small seed core. We found its quality consistent even through 2018’s dry heat; this along with a broader disease resistance package makes it a promising variety for many U.S. regions. Resistant to DM, PM, Scab, CMV.

Additional Information


Cucumis sativus 116 oz packet sows 11 ft; 1 oz, about 180 ft. About 35 seeds/g; 116 oz packet avg 65 seeds, 1,000 seeds/oz.

Days to maturity are from direct seeding, except where noted.

Culture: May be started indoors for early production, or direct-seeded. 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. Transplant 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.

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. Pick cukes frequently for best production, or else the plants shut down. Make sure to remove blimps to the compost pile.

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.

Do not sow in cold soil. Minimum germination temperature 60°, optimal range 65–95°.
