DRRH-5 [IET 27847 (IIRRH-115)], stands as the world’s first coastal salinity-tolerant rice hybrid, developed from APMS-6A × NH 12-124. It was evaluated in AICRIP multi-location Coastal Saline Tolerant Variety Trial (CSTVT) during wet seasons spanning from 2018 to 2022. DRRH-5 consistently out-performed the checks in West Bengal, Gujarat, Goa and Andhra Pradesh with a mean grain yield of 3.7 t/ha in saline conditions and 6.0 t/ha in irrigated conditions. In addition, it exhibited moderate resistance to leaf blast, neck blast, sheath rot and plant hoppers. DRRH-5 has a duration of 124 days (seed to seed) and possesses medium slender (MS) grain type with desirable grain and cooking quality parameters. It was released for cultivation in coastal saline ecosystems of West Bengal, Gujarat, Goa and Andhra Pradesh 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].
