About this variety
RCr-436 was released by Rajasthan Agricultural University (RAU), Jobner. The plant is semi-dwarf and bushy, grows fast early and has bold seed. It is resistant to root rot and root-knot nematodes and suits limited-moisture conditions and the heavy soils of south Rajasthan. Sources give 90–100 days to maturity and a yield of 1,100 kg/ha (about 10–11 q/ha). Its parentage is not published.
Should you pick this variety?
Choose RCr-436 for heavy soil in south Rajasthan where moisture is limited. It is a semi-dwarf, bushy plant that grows fast early and carries bold seed. It is the quickest coriander here with a release behind it, 90 to 100 days against 95 to 105 for Sadhana and 100 to 110 for Gujarat Coriander 2, and at about 10 to 11 q/ha it gives up little for that, since Sadhana gives 10 to 10.3 and Gujarat Coriander 2 gives 12 to 14. It is listed as resistant to root rot and root-knot nematodes. Stem gall is not on that list, and an ICAR-NRCSS paper shows an RCr-436 entry badly hit by stem gall in a Baran district trial. Choose RCr-684 instead if stem gall is common near you, since it is described as resistant. Choose RCr-41 if you can wait 110 days or more.
Sowing & cultivation
Pest & disease considerations
Major diseases
Advantages & considerations
Why farmers may choose it
- Resistant to both root rot and root-knot nematodes, two soil-borne problems that most other coriander varieties here are not listed against
- Quick early growth and bold seed size, valued in the seed trade
Things to consider
- Root rot and root-knot nematode resistance is listed. Stem gall resistance is not. An ICAR-NRCSS paper lists an RCr-436 entry among low-yielding varieties hit by severe stem gall in a Baran district trial (632 kg/ha against 1,198 kg/ha for ACr-1), though its text names RCr-435. Do not assume RCr-436 is safe from stem gall.
- The 1,100 kg/ha and 90–100 days are the same figures given for RCr-684, so treat them as approximate for both.

Match the variety to the disease in your field
Coriander losses come from different diseases, and one variety rarely covers all of them. RCr-436 is listed against root rot and root-knot nematodes, two problems of the root zone. Stem gall, which makes galls on the stem, leaf and flower head, is a different disease.
Before you choose, look at what went wrong in your last coriander crop. Wilted plants with rotted roots point toward RCr-436's strengths. Galls on the stems and flower heads point toward stem gall, where you are better off with RCr-684 or Hisar Sugandh.
ICAR-NRCSS reports stem gall losses of 10.4–57.4%, so it is worth getting this right. If you are not sure what hit the crop, take a plant to your KVK before you buy seed.
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-436 coriander?
Rajasthan Agricultural University (RAU), Jobner. The release year is not published.
Is RCr-436 resistant to any disease?
Yes. It is resistant to root rot and root-knot nematodes. Stem gall is not on that list.
What soil suits RCr-436 best?
Heavy soils of south Rajasthan under limited moisture.
How long does RCr-436 take to mature and what yield does it give?
Sources give 90–100 days and 1,100 kg/ha (about 10–11 q/ha).
What does an RCr-436 plant look like?
Semi-dwarf and bushy, with quick early growth and bold seeds.
Does RCr-436 get stem gall?
It is not listed as resistant. An ICAR-NRCSS paper puts an RCr-436 entry among the low-yielding varieties hit by severe stem gall in a Baran district trial: 632 kg/ha against 1,198 kg/ha for the resistant ACr-1. The same paper names RCr-435 in its text, so the label is not certain. If stem gall is common in your area, choose a variety described as resistant.
Is RCr-436 suited to light sandy soil?
Sources place it on heavy soils of south Rajasthan under limited moisture. None recommends it for light sandy soil, so try a small plot first if your land is sandy.
How is RCr-436 different from RCr-684?
Sources give both the same 90–100 days and 1,100 kg/ha, so the figures may be mixed up between them. The difference is disease cover: RCr-436 is listed for root rot and root-knot nematodes, RCr-684 for stem gall and powdery mildew. The summary above lists RCr-684 at 110–120 days.
RCr-436 or RCr-41 — what decides?
Days and soil. RCr-436 is ready in 90–100 days, suits heavy soil with limited moisture in south Rajasthan and is resistant to root rot and root-knot nematodes. RCr-41 needs 130–140 days and is the one to take if you can wait and like early flowering. Neither is rated for stem gall, so if that is your problem look at RCr-684.
Is the 1,100 kg/ha figure for RCr-436 reliable?
Treat it as approximate. The 1,100 kg/ha and the 90–100 days are the same figures given for RCr-684, so they may be mixed up between the two. Budget on 10–11 q/ha, as given above, and keep your own plot records. An ICAR-NRCSS paper also lists an RCr-436 entry among low-yielding plots hit by stem gall in a Baran trial.
