DRR Dhan 55 [IET 26194(RP 5591-123-16-2)], an aerobic rice variety developed from MTU1010/ IR79915-B-83-4-3 cross combination. It was evaluated in AICRIP multi-location aerobic rice trials during wet seasons of 2016 to 2019. DRR Dhan 55 consistently out-performed the check varieties in Eastern Zone (Zone III) and Central Zone (Zone V) with a mean grain yield 4974 kg/ha, which is 15%, 19% and 18 % higher than National check, Zonal and Local checks, respectively. In addition, it exhibited moderate resistance to Leafblast and Neck blast; and also resistance to gall midge and rice thrips; and moderate resistance to plant hoppers. DRR Dhan 55 has medium duration of 120-130 days (seed to seed) and possess desirable grain and cooking quality parameters. It was released for cultivation in aerobic ecosystems of Bihar (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. 500(E) dt. 29th Jan 2021[CG-DL-E-03022021-224901]
