DRR Dhan 64 [IET 28358 (RP 5599-212-56-3-1)], an early transplanted rice variety was developed from MTU-1010/KMR-3R cross. It was evaluated in AICRIP multi-location ETP trials during wet seasons of 2019 to 2021. DRR Dhan 64 consistently out-performed the check varieties in Eastern Zone (Zone III) with a mean grain yield 5330 kg/ha, which is 8%, 28% and 12% higher than National check, Zonal and Local checks, respectively. In addition, it exhibited moderate resistance to Leaf blast and Neck blast; and also resistant to gall midge and rice thrips; and moderately resistant to planthoppers and whorl maggot. DRR Dhan 64 has early duration of 115-120 days (seed to seed) and possesses desirable grain and cooking quality parameters. It was released for cultivation in aerobic ecosystems of Bihar and West Bengal (Zone III) states through Central Sub-committee on Crop Standards, Notification and Release ofVarieties for Agricultural Crops vide S.O. 4065(E) dt. 31stAug 2022 [CG-DL-E-31082022-238490].
