About this variety
JRO-8432, popularly named Shakti Tossa, is a tossa jute (Corchorus olitorius) variety released by ICAR-CRIJAF in 1999. It has non-shattering pods and is specifically bred to resist premature flowering under early sowing, making mid-March to late-April its optimum sowing window — earlier than most tossa varieties can tolerate — and is recommended across the medium and upland areas of the entire olitorius (tossa) belt.

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: no source found this phase specifies a particular subset of states for JRO-8432 beyond "the entire olitorius belt" generally — this record's existing two-state (West Bengal, Assam) field is not contradicted by anything found, only unconfirmed as complete, so states is left as-is.
- No parentage/cross information was found for JRO-8432 this phase, unlike JRO-524 and JRO-66 — its exact breeding lineage remains unstated rather than guessed.

Frequently asked questions
Who released JRO-8432 (Shakti Tossa) and when?
ICAR-CRIJAF, Barrackpore, released it in 1999. Its exact parentage/cross was not found in any source fetched this phase.
How early can JRO-8432 be sown?
As early as mid-March, without the premature flowering that would affect most other tossa varieties at that sowing date — this is its specific bred-in trait.
How does JRO-8432 compare to JRO-524 for early sowing?
Both resist premature flowering under early sowing — JRO-524 tolerates sowing as early as mid-March, and JRO-8432's optimum window (mid-March to late-April) overlaps closely, making both suitable choices for early-season tossa cultivation.
What fibre yield does JRO-8432 give?
Corroborated secondary sources report 35–40 q/ha — this record's yieldPotential field was corrected to that range.
Does JRO-8432 have non-shattering pods?
Yes — sourced material confirms non-shattering pod type, a trait shared across most of the modern CRIJAF tossa releases in this dataset.
