Quick Summary of Priamurskiy Krupnoplodniy (Amur Large-Fruited)
- 🌍 Origin: A reliable Soviet-era heirloom bred by the Far Eastern Research Institute of Agriculture. Seeds were widely distributed to Russian collectors in 2003. The name translates to “Amur Large-Fruited”.
- 🌿 Plant Habit: Indeterminate, tall (around 1.5–1.8 m / 5–6 ft), and vigorous, but not overly aggressive. Performs best in a greenhouse, though it can grow outdoors in warmer microclimates. Can be grown in 1 to 4 stems depending on your soil fertility.
- 🍅 Fruit Characteristics: Beautiful pink, oblate (flat-round) beefsteaks with slight ribbing/pleating at the shoulders. Fruits are massive, averaging 400–500 g (14–18 oz), with many reaching 600–800 g (1.3–1.7 lbs). The flesh is very meaty with a granular texture on the break and small seed cavities.
- 👅 Flavor: A top-tier dessert flavor. Extremely sweet, rich, and bright, even in cold or cloudy summers.
- ⏳ Maturity: Early-mid to Mid-season.
- 💡 Pro Tips for Growing:
1. Support is mandatory: The fruit trusses get incredibly heavy and will snap if not tied up individually.
2. Pruning: Thin the clusters to 3–4 fruits for maximum size.
3. Feeding: This variety is a heavy potassium (K) feeder. Ensure adequate potassium levels to prevent yellow shoulders or white cores, especially during heatwaves.
A mid-season, vigorous variety bred by the Far Eastern Research Institute of Agriculture. About 10 years ago, seeds were sent out by a gardening magazine to collectors for trials… I’ve been growing it ever since. I even kept the original seed packet from 2003—the breeders back then really knew how to create reliable varieties!
The variety is large-fruited, with an average fruit weight of 400-500 g (14-18 oz), and sometimes even more. The fruits are pink, slightly pleated at the stem end. The flesh is dense, with a granular texture when broken, and boasts top-tier dessert flavor. It is mainly a slicing variety, but also great for juices.
Important: You must tie up every single fruit truss to prevent them from snapping under the massive weight.
Growing it all these years, I realized that improving your soil and care significantly increases its yield. It’s advisable to regulate the load on the fruit trusses, leaving the largest 3-4 tomatoes per cluster. I recommend growing it in 1-2 stems, securing each to the trellis.
I absolutely loved the taste of Amur Large-Fruited! It was sweet even during our cold, gloomy August. Another big plus: it stores much longer than most other large beefsteaks. Thank you to everyone who preserved and spread this worthy variety!
I really liked this variety! Despite our snowless and difficult summer, it produced a crop. There weren’t hundreds of them, but all the tomatoes were uniformly huge. I think with favorable weather, this variety would be even more productive and perhaps even larger. My biggest was almost 800 g (1.75 lbs)!
In 2018, it was voted the most delicious tomato by everyone who ate my harvest. It has a very rich and bright taste when fully ripe. The yield was average because it didn’t set well during extreme heat, but in September it set a lot of large fruits at the top of the plant. I loved it so much that I will plant it every year.
Update: This year it is once again among my flavor leaders. Very saturated, sweet, bright taste. Just an explosion of flavor! Very juicy and the yield is fine. Weight is 400-500 g (14-18 oz). It dropped some blossoms in the heat, but nothing critical. Love forever!
I periodically repeat this variety. It’s a heavy yielder. In 2024, the fruits were huge all the way up the plant. Unfortunately, during the extreme heat, the plant couldn’t absorb potassium well, so there were some white veins/shoulders. (Editor’s note: Many growers mention this variety is a heavy potassium feeder). But despite that, I will never take it off my permanent grow list!
