Answer: Uttar Pradesh
Notes: Researchers at Banaras Hindu University (BHU) have recently revived the traditional black rice Adam Chini using mutagenesis, making it shorter, faster-maturing, and higher-yielding without losing its aroma. Adam Chini, also called Adamchini Chawal, is an aromatic black rice with sugar crystal–like grains and strong fragrance. It is traditionally grown in Chandauli, Varanasi, Mirzapur, and Sonbhadra districts of Eastern Uttar Pradesh in the Vindhya foothills. It received a Geographical Indication (GI) tag on 22 February 2023, valid till November 2030.
