About this variety
IC 112531 is an aloe vera accession in the ICAR-NBPGR gene bank. IC means Indigenous Collection. It is not a released variety. Leaf rot is one of the main limits on aloe production, and the authors of the Kumarganj study say it cuts the leaf, the gel and the gel quality. At NDUAT, Kumarganj, Faizabad, in the kharif seasons of 2014 and 2015, 26 genotypes were planted from old suckers at 50 × 40 cm and scored on a 0 to 5 scale for the fungus Fusarium oxysporum. None was free of the disease. IC-112531, IC-111280 and IC-112513 were rated highly resistant. The same accession was also grown at ICAR-DMAPR, Boriavi, Gujarat, from 2019 to 2021, among 26 accessions cut at about 18 months. There it was below average: a leaf of 146.93 g against 205.63 g, a leaf yield of 55.64 t/ha against 78.62, and a fresh gel yield of 45.30 t/ha against 62.74. The two trials are from different places, so use them to choose planting material for a trial block, not to forecast income.
Should you pick this variety?
Choose IC 112531 only if leaf rot is already a problem on your land and you accept a lower yield for it. It was one of three accessions rated highly resistant at Kumarganj, but at Boriavi it gave 45.30 t/ha of fresh gel against a trial average of 62.74 and less than half of IC 310618's 93.55. Another highly resistant accession, IC 111280, has a gel result as well (58.8% more than the average of 15 genotypes at Ranichauri), so test the two side by side. If leaf rot is not a problem where you farm, IC 310618 or IC 310623 are the better test plants. Fix drainage first. Start with 20 suckers.
Key characteristics
Sowing & cultivation
- Sowing timeJune–July or September–October (TNAU).
- SpacingTNAU gives 90 × 90 cm on prepared beds, 10,000 suckers per hectare. The Boriavi trial used 60 × 45 cm and the Kumarganj screening used 50 × 40 cm.
- Sowing methodPlant suckers cut from healthy plants. Dip them in 0.1% carbendazim for 5 minutes before planting (TNAU).
- IrrigationMainly rainfed. Give 4 to 5 irrigations in the summer months (TNAU).
- HarvestingTNAU: first harvest 6 to 7 months after planting, and gel extraction within 6 hours of cutting. The Boriavi plants were cut at about 18 months.
Soil & climate
Soil
- Suitable soil
- Well-drained laterite to loamy soil, pH 7.0 to 8.5. Waterlogging rots the plant (TNAU).
Yield & maturity
Maturity period
Plants were cut at about 18 months in the Boriavi trial; TNAU gives the first harvest at 6 to 7 months for aloe in general
Expected yield
Below the trial average at Boriavi, Gujarat: 45.30 t/ha fresh gel against an average of 62.74, worked out for 60 × 45 cm spacing
Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.
Pest & disease considerations
Advantages & considerations
Why farmers may choose it
- Rated highly resistant to leaf rot in a field screening of 26 genotypes at Kumarganj, one of only three.
- About 7.63 suckers a plant at Boriavi against a trial average of 6.75, so it gives planting material for the next bed.
Things to consider
- Its gel and leaf yield at Boriavi were clearly below the trial average. The gap in fresh gel (17.44 t/ha) is larger than the trial's 5% margin of 10.26 t/ha.
- The disease score and the yield come from two different trials in two different places, so no single field has shown both together.
- Resistance is not immunity. No genotype at Kumarganj was free of leaf rot, and standing water still rots aloe.
- ICAR-DMAPR sells aloe vera suckers, but its price list does not name an accession. Ask before you buy.

Resistance or yield: how to weigh a plant that gives up some of one for the other
IC 112531 shows how two good traits can sit in different plants. At Kumarganj it was one of three accessions out of 26 rated highly resistant to leaf rot. At Boriavi it gave 45.30 t/ha of fresh gel, 28% under the trial average and less than half of the 93.55 t/ha of the best accession. No trial we found grew the same accessions in one field and scored both yield and disease.
So think about what leaf rot costs you. TNAU says rotting comes under waterlogged conditions and is overcome by good drainage, so on well-drained beds a high-yield accession such as IC 310618 may never meet the disease. On land where water stands or where you have already lost plants to rot, a resistant accession is a sensible hedge, but a hedge that gives lower yield in a good year.
A fair test on your land: put 20 suckers each of IC 112531 and IC 310618 on the same bed, 90 × 90 cm apart, with the same drainage. Count how many plants rot in each rainy season and weigh the gel per plant at your first cut, extracting it within 6 hours as TNAU advises. If IC 310618 loses plants and IC 112531 does not, you have your answer for your own field.
Can you save seed from this crop?
This one is raised from planting material — suckers, grafts, cuttings or tubers — not from a seed packet. Take it from a registered nursery or a government farm, so the plant is true to the variety and free of disease.

Frequently asked questions
How resistant is IC 112531 to leaf rot?
It was rated highly resistant, one of three out of 26 genotypes. At NDUAT, Kumarganj, in the kharif seasons of 2014 and 2015, the plants were set out from old suckers at 50 × 40 cm and scored for the fungus Fusarium oxysporum on a 0 to 5 scale. None of the 26 was free of disease. The other highly resistant ones were IC-111280 and IC-112513. That is good news, not a guarantee, so keep the bed drained.
How much gel does IC 112531 give?
Less than most. At Boriavi, Gujarat, it gave 45.30 t/ha of fresh gel against a trial average of 62.74 t/ha and 93.55 t/ha for the best accession. Its leaf weighed 146.93 g against 205.63 g, and leaf yield was 55.64 t/ha against 78.62. These are plot results scaled up for 60 × 45 cm spacing, so a farm at 90 × 90 cm gets less per hectare, but the ranking against other accessions is the useful part.
Should I plant IC 112531 or IC 111280 for leaf rot?
Both were rated highly resistant in the same Kumarganj screening, so on disease they tie. IC 111280 also has a gel result: 58.8% more gel than the average of 15 genotypes at Ranichauri, Uttarakhand. IC 112531 has a poor yield result from Boriavi. That favours IC 111280, but the two yield tests are from different places and cannot be compared directly. Plant 20 suckers of each and weigh your own gel.
What else can I do to keep leaf rot away?
TNAU says no pest or disease is noticed in aloe, except rotting under waterlogged conditions, which good drainage overcomes. So raise the beds and do not let water stand. Dip suckers in 0.1% carbendazim for 5 minutes before planting. Cut suckers only from healthy plants, never from a bed that had leaf rot, because the rot can travel on the planting material.
Does IC 112531 give enough suckers to multiply?
Slightly more than average. At Boriavi it carried 7.63 suckers a plant at about 18 months, against a trial average of 6.75. ICAR-DMAPR, Boriavi, Anand, Gujarat, sells aloe vera suckers at Rs 5 each, and Rs 3 each above 500 (price list dated 9 May 2024). The list names no accession, so call 02692-271602, ask whether IC 112531 is available, and get the accession number, the place and year, and a promise of healthy plants, all in writing. Do not buy on the name alone.
