Heirloom Marriage ™ Genuwine Tomato

Heirloom Marriage ™ Genuwine Tomato


70-75 days. By crossing 2 beloved heirlooms together, the resulting cultivar bears the best qualities of both parent varieties with the added benefits of hybrid vigor, disease resistance, uniformity and yield.

These luscious, ruby-red slicers are the result of a cross of Brandywine and Costoluto Genovese, two of our most delicious heirloom varieties. This fusion produces beautiful, slightly squat, globe-shaped tomatoes with the most delectable flavor. The indeterminate plants are ready to harvest two weeks before either of the parent plants.
Also available as a plant.

Days to maturity are calculated from date of transplant.

Determinate tomatoes: grow compactly, sprawling laterally, usually do not require staking, and fruit ripens over a short period of time
Indeterminate tomatoes: grow on long vines, generally require pruning to 1 or 2 leaders that need to be trellised
• Fertile, well drained, raised beds covered with plastic mulch promote early growth and better yields
• Tomatoes are high feeders and will benefit from regular fertilization with Age Old Bloom
• To prevent blossom end rot use a high calcuim amendment
• Overwatering can cause fruit to crack

Direct Sowing
• Not recommended

• Sow seeds in trays 6-8 weeks before anticipated transplant date; up-pot into 3-4 inch pots when the first set of true leaves appears
• Strong light and cooler temperatures (60-70°F) prevent plants from getting leggy
• Fertilize with Age Old Grow every 10-14 days
• When transplanting work in compost, 1/2 cup of TSC's Complete fertilizer, and handful of bone meal
• Determinates can be spaced 18-24 inches apart, indeterminates 24-36 inches apart
• Tomatoes can be buried up to the top 2 sets of leaves
• Use Kozy-Coats or Victorian Bell Cloches to protect young plants

Insects & Diseases
Common insects: Flea beetles and tomato hornworms
Insect control: Pyrethrin or row cover for flea beetles, and Monterey B.t. for tomato hornworms
Common diseases: Early and late blight
Disease prevention: A strict 3-4 year rotation, remove vines at the end of the year, fungicide

Harvest & Storage

We were very satisfied with this tomato variety. Our plants were tall and strong and very high yielding. The tomatoes were large and very delicious. My husband said they were the best tasting tomato he ever tasted. We had none of the disease problems we have had in the past with heirlooms. We will be growing this tomato again.
Great main season tomatoes!

Great tasting and a really beautiful tomato. These were much more prolific than a regular heirloom. We will definitely grow this again!
Good Choice for Heirloom

If you have been disappointed by heirlooms in the past, I recommend this one. High Yield and Heirloom taste. First fruits were misshapen and mealy, but improved quickly. The plant grows quite large, so you need space. You will get some that look like the catalogue picture, but expect some shoulder ribbing and green as well as blossom end scab. I did not have the problem with seeds one other reviewer mentioned. Fruits were meaty, not overly juicy.
VERY Disappointed!

I had high hopes for this tomato, but it has been a HUGE disappointment. Super seedy (never seen so many seeds in a tomato) - and unlike most tomatoes, that have the seed/gel compartment surrounded by generous flesh, with Genuine, the seeds are distributed pretty much all over the flesh. By the time you take the seeds out, all that's left is a bit of mushy flesh and skin. The flavor is so-so, growth is indeed vigorous and production is also good but the tomatoes are small - esp compared to Brandywine. I was hoping for a tomato like Brandywine that matured earlier and produced more fruit, but all in all, volume wise with Brandwine's very large size, you end up with more -- AND at a much less price. Save your money and stick with Brandywine, or Berkeley Tie-Dye, now that is an excellent tomato I also tried for the first time this year, and produced just as well, much more beautiful tomatoes, great plant vigor, and deep, complex flavor with that perfect tart balance. All that and open-pollinated to boot.

I'm delighted! This tomato has everything I want.. the size of a slicer with the taste of an heirloom that actually ripens on the vine during the short summer of Western Puget Sound Washington. I will be buying this again!
