About this variety

Manik Chaman is a spontaneous clonal mutant of Thompson Seedless — selected by grape growers around 1982, not released through a formal ICAR or university breeding programme — distinguished by its elongated berries, medium ripening season, and sweet 20–22°Brix juice. It is grown mainly for raisin-making, with fresh table use as a secondary market.

Advantages & considerations

Things to consider

  • No ICAR/university release record found — Manik Chaman appears to be a farmer/grower-selected clonal mutant of Thompson Seedless (circa 1982), not an institute-bred variety; treat any formal "release" framing with that caveat.
  • Reviewed 2026-08-15: one source describes Manik Chaman as having "low yield potential" with a "medium" growing season, which sits at odds with this record's existing 'Very high' yieldPotential rating — but it is a single, unconfirmed, hedged source contradicting a qualitative band rather than a hard number, so the rating is deliberately left as-is pending a stronger source.
  • Being a direct clone of Thompson Seedless, it plausibly shares that parent's general disease susceptibilities, broadly consistent with this record's existing 'Mildew-susceptible' rating, though no source directly confirmed disease response for Manik Chaman specifically.

Frequently asked questions

Is Manik Chaman a distinct breed or a version of another grape?

It is a clonal mutant of Thompson Seedless, selected by grape growers around 1982 for its elongated berries — not an independently bred variety.

What is Manik Chaman mainly used for?

Mainly raisin-making, thanks to its sweet 20–22°Brix juice; fresh table consumption is a secondary use.

Is Manik Chaman really a "Very high" yielder?

This record's existing rating says so, and it is kept as the working reference — one sourced description called it a low-yield, medium-season type, but that is a single hedged source contradicting a qualitative band, not a confirmed correction, so it was reviewed 2026-08-15 and deliberately left as-is pending stronger sourcing.

How disease-prone is Manik Chaman?

This record's existing 'Mildew-susceptible' rating is plausible given its Thompson Seedless parentage, though not independently confirmed for Manik Chaman specifically this phase.

What does the berry look like?

Elongated (oval) berries, larger and crisper than typical round Thompson Seedless berries, with a rich sweet flavour.
