About this variety
TKG-22 is a sesame variety tied to Jawaharlal Nehru Krishi Vishwa Vidyalaya (JNKVV), Jabalpur, Madhya Pradesh, and has long served as the national check variety in the AICRP (All India Coordinated Research Project) on Sesame and Niger — the benchmark that newer candidate varieties are measured against before being recommended for release. Its synchronous maturity trait, where most capsules ripen together rather than in a staggered fashion, meaningfully reduces the shattering losses that are otherwise a major cause of low harvestable yield in sesame.

Things to consider
- No release year was found for TKG-22 despite searching — it is cited across the literature mainly in its role as a long-standing check variety, not with a dated release notification.
- In AICRP coordinated trials pooled across 32 locations over 2007-2009, TKG-22 (as the check) recorded a mean yield of about 577 kg/ha (~5.77 q/ha) — well below this record's existing "Medium-high" yieldPotential framing. This is a multi-location trial mean used as a comparison benchmark for newer entries, not necessarily representative of the variety's potential yield under strong farmer-field management, so it is reported here as a data point rather than a correction to the existing field.
- No specific disease-resistance data was found for TKG-22 itself this phase — this record's existing "Tolerant to leaf spot" field is left unconfirmed and uncontradicted.

Frequently asked questions
What role does TKG-22 play in India's sesame breeding programme?
It serves as the national check variety in the AICRP on Sesame and Niger — the reference standard that new candidate varieties are compared against in coordinated multi-location trials before a release recommendation is made.
Why does synchronous maturity matter for sesame yield?
Sesame capsules shatter and drop seed as they ripen; when maturity is staggered, growers either harvest too early and lose unripe capsules or wait and lose the earliest-ripening ones to shattering. Synchronous maturity narrows that window and cuts the loss.
Is TKG-22 still a good choice for a farmer to grow today?
It remains a viable, well-understood Madhya Pradesh variety, but since it is primarily used as a research check, several newer JNKVV/AICRP releases have since been bred to outyield it — worth comparing against current local recommendations before choosing.
Which institute maintains TKG-22?
It is maintained at the Project Coordinating Unit of the AICRP on Sesame and Niger, based on the JNKVV campus in Jabalpur, Madhya Pradesh.
What does the 577 kg/ha trial figure actually measure?
It is TKG-22's pooled mean yield as the check variety across 32 AICRP trial locations over 2007-2009 — a multi-location research benchmark, not a single farmer-field yield figure, so it should not be read as a ceiling on what the variety can produce under good local management.
