DRRH-4 [IET 27937 (IIRRH-124)], is an aerobic rice hybrid developed from APMS-6A / AR 9-18 cross. It was evaluated in AICRIP multi-location aerobic rice trials during wet seasons of 2018 to 2021. DRRH-4 consistently out-performed the check varieties in Punjab, Odisha, Chhattisgarh, Tripura and Gujarat states with a mean grain yield 5030 kg/ha, which is 32%, 28%, 22% and 11% higher than national check, zonal, local and hybrid checks, respectively. In addition, it exhibited moderate resistance to leaf blast, neck blast, gall midge, rice stem borer, and whorl maggot. DRRH-4 has early duration of 120 days (seed to seed) and possess desirable grain and cooking quality parameters. It was released for cultivation in aerobic ecosystems of Punjab, Odisha, Chhattisgarh, Tripura and Gujarat states through Central Sub-committee on Crop Standards, Notification and Release of Varieties for Agricultural Crops vide S.O. 4065(E) dt. 31st Aug., 2022 [CG-DL-E-31082022-238490].
