DRR Dhan 57 [IET 26171 (RP 5601-283-14-4-1)], an aerobic rice variety was developed from BPT5204/ Azucena cross combination. It was evaluated in AICRIP multi-location aerobic rice trials during the wet seasons of 2016 to 2020. DRR Dhan 57 consistently outperformed the check varieties in Eastern Zone (Zone III) and Central Zone (Zone V) with a mean grain yield of 4782 kg/ha, which is 13%, 17% and 16 % higher than the National, Zonal and Local checks, respectively. In addition, it exhibited moderate resistance to leaf blast and Neck blast; and to gall midge and rice thrips, and moderate resistance to planthoppers and whorl maggot. DRR Dhan 57 has a mid-early duration of 120 days (seed to seed) and possesses desirable grain and cooking quality parameters. It was released for cultivation in aerobic ecosystems of Jharkhand (Zone III), and Chhattisgarh (Zone V) states through Central Sub-committee on Crop Standards, Notification and Release of Varieties for Agricultural Crops; vide S.O. 8(E) dated 24th December 2021[CG-DL-E-04012022-232406].
