Kazakhstan Yellow (Kazakhskiy Zheltyy) Tomato Review & Photos

Rate this

📌 Quick Summary (TL;DR): Kazakhstan Yellow

  • 🌍 Origin: A legendary underground heirloom from the Russian/Eastern European tomato community. It was grown for over 25 years by a forum member named Slava before he finally shared the seeds online and gave it the working name “Kazakhstan Yellow.”
  • 🌿 Plant Habit: Indeterminate (tall). A very resilient and vigorous vine. It performs exceptionally well in both greenhouses (reaching the roof) and outdoors in the dirt (where it typically tops out around 5 feet / 1.5 m).
  • 🍅 Fruit Characteristics: Large, flattened-round (oblate) yellow beefsteaks. The true hallmark of this variety is a distinct red or pink “starburst” blush in the center of the flesh when fully ripe. Weights usually range from 8 to 17 oz (250-500 g).
  • 👅 Flavor: Classic sweet yellow tomato profile with very low acidity. The flesh is dense, meaty, and very juicy. Highly rated for fresh eating, but be careful not to let them overripen on the vine, or they can become watery.

KAZ. YELLOW

I got this variety (the name is just a working title) from our forum member Slava. Slava can jump in later and add its full name. The variety is indeterminate (though honestly, all my indeterminates just terminate wherever the greenhouse roof begins…). Extremely heavy yielder and very tasty. Bright yellow color. Mine came out in all different sizes, from 4 oz up to 12.5 oz (120 to 350 g). I really loved it! Slava, thank you!!! 🙏 🙏 🙏 🙏 🙏

Tanya, it’s a working title for me too, I just made the name up myself. I sent it to Tomatinka to help identify it, but she didn’t plant it this year. Guess we’ll wait for next year. It’s been growing in my garden for about 25 years and I honestly don’t remember where it came from.

You are very welcome, but your beauties look a lot thicker and plumper than mine, coming from a rough-and-tumble Siberian miner like me. 🤣

Slava shared some seeds of Kaz. Yellow with me at the Moscow meet-up in late March, so I originally put them aside for next year. But my curiosity won out, and I sowed them in early April. Planted them out in the dirt with only five true leaves (a tiny little seedling) on May 20th. But Slava’s protégé took off extremely fast and caught up to the other indeterminates. The plant is a very heavy yielder. The fruits are a beautiful yellow color, they almost look like glowing amber when the sun hits them. The taste is sweet. Mine had absolutely zero tang or acid to them. This is how Kaz. Yellow from Slava turned out for me.

I’ll say it again – every single tomato needs to have a crimson red blush inside the flesh that you can’t see from the outside.

Galina, how and what do you tie your indeterminates to out in the open ground? My cherries are already over 3.3 feet (1 meter) tall, I’ve lowered them a bit, but I have no idea what to do with them next.

Thanks to our Slava for this beauty! Gave me the seeds at the February meet-up. I only had one plant, about 5 feet (1.5 m) tall, it set 10 tomatoes weighing from 7 to 16 oz (200 to 450 g). The yield across all my tomatoes was pretty average this year, the 3rd and 4th trusses almost entirely aborted (I pruned everything to 1 stem). I couldn’t even wait for the pink blush to appear inside – we ate them up instantly even when they were slightly underripe. The biggest one did have the beginnings of a blush though 😉 Saved the seeds, this is my new favorite now!

I grew it in open ground. It turned out tasty, productive, the pink blushes inside were small but they were there. However, it ripened almost last out of all my varieties, only at the end of August. Much later than the bi-colors and tri-colors.

And here is my Kaz. Yellow 🙂 Grew in the greenhouse on 2 stems. Early, heavy yielder, and tasty variety 👍 The fruits aren’t huge, around 7 oz (200 g), and on a vertical slice you can sometimes see the pink blush.

Because of the heat in the greenhouse, a lot of my blossoms dropped. The ones that did set grew out large, but overall the yield was pretty low. I agree that they are early and tasty though.

My favorite of the 2016 season. The tastiest, sweetest, and heavy yielder. The blush was visible when sliced. I’m planting more of these next year, one plant is just not enough for such a fantastic variety.

Aglaya, I think it’s better to plant 2 to a hole only for plants with a generative growth habit (like most oxhearts). They honestly don’t care if they are crowded or not. Kazakhstan Yellow doesn’t fall into that category.

I’m also very happy with Kazakhstan Yellow. The blush wasn’t present in every fruit. Yield in the hoop house was excellent. The fruits were tasty and sweet. They cracked a little bit because of overwatering.

I sowed mine on March 16th. Moved it to its permanent spot by transplanting it from the open ground (I put my greenhouse up late). First ones ripened July 27th, I think they would have been earlier, but they were delayed by the transplant shock. 🙂

Kazakh Yellow is a stable, reliable variety, Slava (LLL) has had it for many years, year after year.

A stray seed probably just ended up in your seedling cup, or earlier, in the seed packet.

Rare yield for open ground, the plant was literally breaking under the weight 👍 and most importantly – it’s early. The base spoiled a little bit.

Very tasty and productive tomato. It grew almost to the roof in the greenhouse, didn’t push too many suckers either. The fruits are oblate, sweetish, meaty, and juicy, weighing about 9-10.5 oz (250-300 g). My family really loved it for its taste and thin skin. Slava, thanks for the seeds!

I planted it this year too. Grew 2 to a hole. Heavy yielder, but not early for me. Beautiful, and it had the internal blush… but if you blink, it gets overripe, goes soft, and becomes almost transparent and watery.

Thanks to Elya (elja1968) for the seeds.

Turned out to be a heavy yielder, average tomato weight 9-10.5 oz (250-300 g). The internal blushes didn’t appear right away, the fruits on the lower trusses had no blush at all 🙂

Rich tomato flavor. Height in the greenhouse was around 5.5 feet (1.7 m).

Not too aggressive, didn’t get overgrown with a ton of suckers.

In my opinion and to my taste, yellow tomatoes usually have too mild of a flavor. But this one turned out to be really tasty! And productive. Quite early. The pink blush didn’t show up immediately. It wasn’t there on the first few tomatoes. Strong, tall plant. It fruited until the end of the season, I was picking green ones in September. Ripened perfectly indoors on the counter. Seeds from Olya Zolushka. Thanks to her! 🙏

Did I really just find my absolute favorite?!!!! 😘 I used to grow a similar tomato for several years, out in the dirt under row covers, originally from a packet named Lemon Giant (not the modern Giant Lemon). It was always the first to ripen, a tender fruit, thin skin, bursts easily, the flavor is also delicate—some might call it mild. I grew it for about 10 years from my own saved seeds, but then I lost it(( When the first bicolors hit the market here, I would say, “Pfft, I already have those.” Sigh, I’m going to have to order this one…

I was refreshing my seed stock. A good, worthy tomato. The flesh is quite dense and juicy, makes a great companion to red tomatoes in a salad to get a full spectrum of flavor.

The flavor is characteristically yellow, a little bit on the mild side, but it pairs really well with others in a salad.

👨‍🌾 Editor’s Note: The Internal “Necktie”
Throughout this thread, you’ll see growers talking about a “necktie” (галстук). This is classic Russian heirloom slang! When a yellow, orange, or green beefsteak tomato has a prominent red or pink starburst/blush in the center of its flesh, Russian growers call it a “necktie.” It is the ultimate sign that the tomato is fully ripe and true-to-type. If a yellow heirloom is supposed to have a “necktie” but doesn’t, it usually means the fruit was picked too early or the seeds got crossed!
