About this variety
GT 10 (Gujarat Til 10) was released for commercial cultivation in 2002 by the Agricultural Research Station at Amreli, a sesame-breeding centre under Junagadh Agricultural University, developed by selection from the line TNAU 17. It is a black-seeded variety with profuse branching and medium (around 120 cm) plant height, maturing in about 92–95 days per multiple sources — a touch longer than this record's existing 85–90-day field. Its standout trait in the plant-breeding literature is field resistance to Phytophthora blight: coordinated varietal trials recorded just 3.74–5.92% disease intensity under high disease pressure, well below susceptible checks. No primary JAU or ICAR page could be directly fetched for this record (every attempt returned unreadable binary or a 403); the facts here rest on multiple independently-corroborating WebSearch summaries instead.

Maturity period
85–90 days
Expected yield

Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.
Pest & disease considerations
Major diseases
- Field-resistant to Phytophthora blight — 3.74–5.92% disease intensity recorded in coordinated varietal trials under high disease pressure, well below susceptible checks
- No source found in this pass discusses leaf curl specifically (the tolerance this record's existing diseaseResistance field credits it with) — not contradicted, just not independently confirmed here
Advantages & considerations
Why farmers may choose it
- Black seed colour, valued in some til markets as a distinct product from the more common white/brown sesame
- Recorded yield potential up to 1,671 kg/ha under rainfed conditions at Amreli — above this record's conservative 6–8 q/ha field
Things to consider
- Reported maturity (92–95 days) runs a little longer than this record's existing 85–90-day duration field, and its trial-station yield ceiling (up to 1,671 kg/ha) runs well above the existing 6–8 q/ha field — both stated here as reported ranges rather than replacing the existing figures.
- No source in this research pass could be directly fetched (JAU's own variety-release PDFs returned as unreadable binary, and academic mirrors 403'd); every fact above rests on multiple independently-corroborating WebSearch summaries rather than a read primary document, so no `sources` array is attached to this record.

Frequently asked questions
Why is GT 10 sometimes called a black sesame variety?
Its seed coat is black, distinguishing it from the white-seeded RT 351 and brown-seeded TMV 7 — a trait some til markets pay a premium for.
Is GT 10 really an irrigated summer (zaid) variety?
The research behind its release (Phytophthora blight resistance trials, yield at Amreli) was reported under rainfed conditions, but Junagadh Agricultural University markets it for both zaid and kharif sowing — consistent with this record's season field.
