Abstract
DRR Dhan 70 [IET 29415 (RP 6326-278-14-1)], an aerobic rice variety was developed from MTU 1010 × WGL 505. It was evaluated in AICRIP multi-location aerobic rice trials during wet seasons of 2020 to 2022. The DRR Dhan 70 consistently surpassed the performance of the comparison varieties in Odisha and Bihar states (Zone III), achieving a mean grain yield of 4287 kg/ha. This yield superiority is evident over the national check by 16%, the zonal check by 11% and the local check by 18%. In addition, it exhibited moderate resistance to leaf blast, brown spot, sheath rot, rice tungro, plant hoppers, stem borer, gall midge and leaf folder. DRR Dhan 70 has a duration of 120 days (seed to seed) and possesses desirable grain and cooking quality parameters. It was released for cultivation in aerobic ecosystems of Odisha and Bihar (Zone III) states through Central Sub-committee on Crop Standards, Notification and Release of Varieties for Agricultural Crops vide S.O. 1560(E) dated March 26, 2024 [CG-DL-E-28032024-253429].
