📌 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!!! 🙏 🙏 🙏 🙏 🙏
It’s Kazakhstan Yellow – just a working title 😊

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. 🤣
Gorgeous!

I’ll show off my Kazakhstan Yellow too 🤫
What a stunner! Who is the seed vendor? Or is it a working name? I want these beauties too.
I just keep admiring this variety, added it to my grow list for next year.
Thanks Tanechka (Tomatanya) 🙏
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 didn’t plant it this season, thought late March was too late to start seeds 😞 Slava, I promise I will plant your stunner in 2015.
Oh man, it is absolutely gorgeous. An absolute dream. 🙏
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.
How tall does this beauty get?

Mine definitely hit 5 feet (1.5 m) out in the dirt, and then I topped it.
Thanks, Galochka, 🙏 it’s on my plan, just need to figure out where to put it based on height.

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!
Tasty, heavy yielder.

Wow, what a stunner! Nadezhda, where did you grow it? When did the first tomato ripen?

Grew it in the greenhouse – the first one was ready on July 20th.
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.
First year growing it. Grew in the greenhouse.
Tasty, heavy yielder. I’ll be repeating it.
I didn’t like it. Won’t be repeating it for now.
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.
Grew out in the dirt for me, was one of the earliest to ripen. Productive, tasty, sweet, and it had that signature pink blush inside. I’ll repeat it in a year or so. Thanks to Lyuda (Ovechka) for the seeds, and of course to Slava.
What is the plant structure like? Will it do okay if I plant 2 to a hole?
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.

Thanks, got it.
Dear forum members! Most of you are saying this variety is early. When did you sow the seeds? February or March? (I’m making my planting schedule for Feb-March right now). Thanks! 🙂
I sowed them around March 8th.

I sowed Kaz. Yellow on April 10th (!), planted it out in the dirt in late May. Started ripening in late July.
Ilya, Galina, thank you! 📝
Anyuta wrote:

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. 🙂
I am definitely planting it next season!!!
I have 4 seedlings growing. 3 are short with regular leaves, and 1 (the very first to pop up) is tall with a potato leaf. 🤔 Off-type?
I grew it last year, my plants had regular leaves.
And for me, it was the only one out of 36 sown varieties/hybrids that didn’t germinate. 😞 Waited a whole month, but alas. I really wanted to grow it in my garden.

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.

Hey there! 🙏 Yours flowered first, I’m putting it in the dirt for good tomorrow.

Better do it the day after tomorrow 🎩
My first Kaz. Yellow tomato ripened, around 12.5 oz (350 g), absolutely delicious, growing outdoors.
Wonderful variety. One of the best out of everything I’ve grown and tasted. Gets a permanent spot in my garden beds.
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.

You’re welcome, but yours are a bit on the small side. 🙂 Mine crossed the 1.1 lb (500 g) mark last year. 🎩
Slava, 🎩 how did Kaz. Yellow differ this year?

This year it turned striped. 🙂
Slav, it’s just that kind of year))) My biggest one was around 1.1 lbs (500 g) too.
In my conditions, the flavor turned out pretty basic, it lost to Honey Salvation (Medovyi Spas) and Mennonite, Apricot Brandywine.
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! 🙏
For me, it’s the tastiest out of all the yellows I’ve planted so far. Ripens up great indoors on the counter. I will absolutely be repeating it.
A favorite variety since childhood! Performs really well in both the greenhouse and open ground.
Insanely productive, just loaded with fruit 🙌 with a rich flavor 😋 didn’t get sick at all – what more could you ask for from a tomato!
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.

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!
