Co 86032 (Nayana)
From ICAR-Sugarcane Breeding Institute Coimbatore — the standard high-yielder across the peninsular belt, valued as much for ratooning well as for the first cut.

About this variety
Co 86032 (marketed as Nayana) was bred at ICAR-Sugarcane Breeding Institute, Coimbatore, from the cross Co 62198 × CoC 671. It was identified for the tropical zone in 1994, began spreading commercially from 1996, and was formally notified for release in 2000. It went on to become one of the Institute's best-known releases — by some estimates it occupies over a million hectares across tropical peninsular India today, and it carries an official 'moderately resistant' (MR) rating against red rot. In practice its field record has run well ahead of that formal rating: multiple reports describe fields under Co 86032 staying largely free of red rot across roughly 25 years of cultivation, attributed to a nodal-resistance mechanism, even in seasons when susceptible neighbouring varieties saw 60–80% infection. It is also known as an exceptional ratooner — some growers are reported to have taken 18 or more ratoon crops from a single planting — and for tolerating drought better than most north Indian canes. None of this rests on a directly-fetched primary this pass: the Institute's own site (sugarcane.icar.gov.in) was unreachable and ICAR's agrinnovateindia.com licensing page for this specific variety returned a 404, consistent with the ICAR-domain access pattern seen throughout this rollout, so every figure here comes from WebSearch-corroborated trade and research summaries rather than a fetched official document.

Advantages & considerations
Why farmers may choose it
- A remarkably durable red rot field record — about 25 years of reports describing it staying largely disease-free via nodal resistance, well beyond its official "moderately resistant" rating
- Exceptional ratoonability — some growers report 18+ ratoon crops from one planting, a real saving on replanting cost
- Reported drought tolerance on top of its yield, useful in the less-assured-irrigation tracts of the peninsular belt
Things to consider
- This record's own diseaseResistance field also credits 'moderate smut tolerance' — no source found this pass specifically addressed smut for Co 86032, so that claim is neither confirmed nor contradicted here, just unconfirmed in this pass
- Every fact in this block rests on WebSearch-corroborated summaries rather than a directly-fetched primary — the Sugarcane Breeding Institute's own site and its ICAR licensing page were both unreachable this pass, so there is no `sources` array on this record

Frequently asked questions
Why has Co 86032 stayed relatively free of red rot for so long?
It carries only an official 'moderately resistant' red rot rating, but multiple field reports over roughly 25 years describe it staying largely disease-free through what researchers call nodal resistance, even in seasons when susceptible neighbouring varieties saw 60–80% infection — real-world performance well ahead of its formal rating.
How many ratoon crops can Co 86032 give?
It has a strong reputation as a ratooner — some growers are reported to have taken 18 or more ratoon crops from a single planting, reducing how often the field needs replanting from setts.
