About this variety
TAU 1, sold commercially as 'Taru', is a short-duration blackgram (urad) variety bred by CCS Haryana Agricultural University (HAU), Hisar. A directly-fetched 2023 Frontiers in Plant Science review of blackgram breeding confirms it as one of the varieties with documented resistance to Mungbean Yellow Mosaic Disease (disease score 1, citing Solanki et al., 2011) — independent confirmation of this record's existing yellow-mosaic-resistant rating. Beyond that one confirmed fact, seed-trade and extension listings consistently describe it at 70–75 days maturity and 10–12 q/ha yield, broadly matching this record's own fields, but no directly-fetched HAU or ICAR primary document turned up a release/notification year or parentage cross in this research pass — HAU's own PDF of released and notified varieties returned only unreadable compressed image data, so those two details are left unstated rather than guessed.

Advantages & considerations
Why farmers may choose it
- Independently confirmed Mungbean Yellow Mosaic Disease resistance (Frontiers 2023 review, disease score 1) backs up this record's own disease-resistance rating.
- A slightly wider resistance stack (yellow mosaic virus and powdery mildew) than the nearby Pant U 31, at a few days' extra duration — consistent with this record's own note.
Things to consider
- No directly-fetched HAU or ICAR primary source could confirm an exact release year or parentage cross for this pass — HAU's own PDF of released and notified varieties returned unreadable compressed image data on every fetch attempt, so those two facts are left out rather than stated with false precision.

Frequently asked questions
Is TAU 1's yellow mosaic virus resistance independently confirmed?
Yes — a 2023 academic review of blackgram breeding (Frontiers in Plant Science) lists it with a resistance score matching the strongest rating in its disease-scoring scheme, citing a 2011 study, independent of the seed-trade listings that also describe this trait.
How does TAU 1 compare to Pant U 31?
Sources describe TAU 1 with a broader resistance stack (yellow mosaic virus and powdery mildew, against Pant U 31's only-confirmed yellow-mosaic resistance) at a similar or slightly longer duration — consistent with this record's own note calling it 'a wider disease-resistance stack... at a few days more duration.'
