About this variety
RCr-684 is a coriander variety listed for Rajasthan. Sources do not agree on who released it: some say Gujarat Agricultural University (GAU), Jagudan, although its RCr code points to Rajasthan, and a Karnataka trial paper lists its seed as received from ICAR-NRCSS, Ajmer. It is resistant to stem gall and less susceptible to powdery mildew, suits medium-heavy soil and sandy loam under irrigation, and has bold seed. Some sources give 90–100 days and 1,100 kg/ha, the same figures given for RCr-436, so those may be mixed up. The summary above lists 110–120 days.
Should you pick this variety?
Choose RCr-684 if stem gall is your main worry in Rajasthan. ICAR-NRCSS reports stem gall losses of 10.4–57.4% and, in severe cases, no fruit at all, and RCr-684 is described as resistant, with less powdery mildew too. It suits irrigated medium-heavy soil or sandy loam and has bold seed, with a medium–high yield rating. Plan on 110 to 120 days, a week or so ahead of Hisar Sugandh's 120 to 125, and ask the seller if they quote 90 to 100 days, since that figure belongs to RCr-436. Choose RCr-436 instead for heavy soil with limited moisture, where root rot and nematodes are the problem. Choose Hisar Sugandh if you are in Haryana.

Why farmers may choose it
- Dual disease protection: resistant to stem gall and less susceptible to powdery mildew
- Bold seed size, valued in the seed trade
Things to consider
- Sources do not agree on who released RCr-684. Some name Gujarat Agricultural University, Jagudan, and a Karnataka trial paper lists the seed as received from ICAR-NRCSS, Ajmer. The RCr code points to Rajasthan, so ask the seller where the seed was produced.
- The 90–100 days and 1,100 kg/ha given in some sources are the same figures given for RCr-436, so they may be mixed up. The summary above lists 110–120 days; plan on that.

- Rajasthan
Ask who produced the seed
RCr-684 carries a Rajasthan code but is linked in some sources to a Gujarat university station. That muddle matters less for the plant than for the bag. Seed sold under a popular name from a source you cannot trace may be a different line.
At the shop, ask who produced the seed, ask for the lot number and the test date on the label, and keep the bill. If the seller cannot name the producing station or seed company, buy a small lot first.
In the field, a stem-gall-resistant variety still needs clean seed. The fungus can live in the seed and the soil, so seed of unknown origin can bring the disease along.
Can you keep your own planting material?
This is an open-pollinated variety, so seed from a healthy crop of your own can be sown again. Keep seed only from disease-free plants, dry it properly, store it cool and dry, and bring in fresh certified seed every three to four years so the variety does not drift.

Frequently asked questions
Who released RCr-684 coriander?
Sources differ. Some say Gujarat Agricultural University (GAU), Jagudan, and one trial paper lists the seed as coming from ICAR-NRCSS, Ajmer. The RCr code points to Rajasthan. Ask the seller where the seed was produced.
Is RCr-684 resistant to disease?
Yes. It is described as resistant to stem gall and less susceptible to powdery mildew.
What soil suits RCr-684 best?
Medium-heavy soil and sandy loam under irrigation.
How long does RCr-684 take to mature and what yield does it give?
Some sources give 90–100 days and 1,100 kg/ha, exactly the figures given for RCr-436, so they may be mixed up. The summary above lists 110–120 days; plan on that.
What seed size does RCr-684 have?
Bold seeds.
Does stem gall resistance make RCr-684 safe on every field?
No. Resistance lowers the risk but does not remove it. ICAR-NRCSS says the stem gall fungus survives in soil or seed, so use clean seed and do not grow coriander on the same land year after year. RCr-684 is described as resistant, not immune.
Should I plan on 90–100 days or 110–120 days for RCr-684?
Plan on 110–120 days. The 90–100 days and 1,100 kg/ha seen in some sources are exactly the figures given for RCr-436, so they may have been copied from it. Use the longer figure so you do not harvest before the seed is ripe.
How is RCr-684 different from RCr-41?
RCr-684 is described as stem gall resistant, with bold seed and a medium–high yield rating. RCr-41 has only a moderate disease rating, but it flowers early, with 50% flowering at 42.67 days. Both are listed at 110–120 days shown above, although an agronomy page gives RCr-41 130–140 days.
RCr-684 or RCr-436 — I have heavy soil but stem gall too?
Think about which problem hurts more. ICAR-NRCSS reports stem gall losses of 10.4–57.4% and, in severe cases, no fruit at all, and RCr-684 is described as resistant. RCr-436 handles root rot and root-knot nematodes on heavy soil with limited moisture, but it has no stem gall rating. If stem gall is common near you, RCr-684 is the safer risk.
How much does RCr-684 help against powdery mildew?
It is described as less susceptible, not immune. That means less powdery mildew than a susceptible variety, not none. Keep walking the field in the cool, humid weeks, and spray according to your state's coriander advice if the white powder appears on leaves and umbels.
