It is a cocktail variety, fruit weight is 0.7-1 oz (20-30 grams). There were 16 fruits on the first truss, and 8-10 on the subsequent ones. It looks a lot like Amur Tiger.<\/p>\n<p>In the last photo, Duo is on the right, Tiger on the left. The fruits are slightly different. Duo is rounder, while Tiger is oblate, but visually they look very similar. Duo is more productive and ripens earlier. With simultaneous planting, Duo ripened its third truss while Tiger was only ripening its first. Duo also tastes better, it has a good tomatoey flavor, whereas Tiger is a bit bland.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/attachments\/45469_6dc9a1dba03ba3f570be604e7bb95c6da42d0d66.jpg\" alt=\"Duo tomato plant with heavy fruit trusses\" width=\"840\" height=\"1120\" \/><br \/>\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/attachments\/45471_0a94e143a56cc4469e4e3bf1fddb4bc1f1983522.jpg\" alt=\"Duo tomato fruit on the vine\" width=\"1360\" height=\"1020\" \/><br \/>\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/attachments\/45473_c99a7027174f95ce72d324dadbf8444afb789bea.jpg\" alt=\"Duo vs Amur Tiger tomatoes side by side comparison\" width=\"1280\" height=\"960\" \/><\/p>\n<\/div>\n<\/div>\n<div class=\"forum-post\">\n<div class=\"author-header\">\n<div class=\"forum-avatar\">E<\/div>\n<div class=\"author-meta\">\n<div class=\"author-name\">ElenaN (Elena) <span class=\"author-stats\">\u2b50 Pro Grower (28,513 posts)<\/span><\/div>\n<div class=\"author-geo\">\ud83d\udccd Kostroma, Russia (USDA Zone 4)<\/div>\n<\/div>\n<\/div>\n<div class=\"post-content\">\n<p>Here are my Duos, I only grew one plant.
