About this variety
JRO-66, popularly named Golden Jubilee Tossa, is a tossa jute (Corchorus olitorius) variety developed by ICAR-CRIJAF, Barrackpore, West Bengal, released in 1998 from a multi-parent cross involving six parent lines. It has steel-grey-to-green, non-dehiscent pods at maturity, excellent TD-2-grade fibre quality, and is bred for late sowing — susceptible to premature flowering if sown before mid-April, so it is recommended specifically for the mid-April to early-May window.

Advantages & considerations
Things to consider
- Corrected 2026-08-15: corroborated secondary sources report fibre yield of 35–40 q/ha, well above this record's old "25–28 q/ha" yieldPotential — yieldPotential corrected to "35–40 q/ha".
- Reviewed 2026-08-15: sourced maturity is 145–155 days, longer than this record's existing "115–125 days" duration field — likely a different measurement point (fibre-cutting stage in this record vs. a fuller crop cycle in the source), similar to the pattern seen for JRC-212 elsewhere in this file — duration deliberately left as-is rather than picking one number.
- Corrected 2026-08-15: sourced material adds Odisha to the recommended growing area (alongside West Bengal and Bihar) for the entire olitorius/tossa belt — states corrected to add Odisha.

Frequently asked questions
Who released JRO-66 (Golden Jubilee Tossa) and when?
ICAR-CRIJAF, Barrackpore, released it in 1998, bred from a multi-parent cross involving six parent lines.
Why is it called Golden Jubilee Tossa?
The name commemorates a golden-jubilee milestone (likely tied to CRIJAF's or the jute research programme's anniversary) around its 1998 release, though the exact commemorative event was not independently confirmed this phase.
Why can't JRO-66 be sown early like JRO-524?
It is susceptible to premature flowering if sown before mid-April, the opposite bred-in trait from JRO-524 (Navin), which specifically resists premature flowering under mid-March sowing — the two varieties are bred for different points in the sowing calendar.
What fibre yield does JRO-66 give?
Corroborated secondary sources report 35–40 q/ha — this record's yieldPotential field was corrected to that range.
Which states grow JRO-66?
Sourced material recommends it across the entire tossa (olitorius) belt, naming West Bengal, Bihar and Odisha specifically — this record's states field was corrected to add Odisha.
