The application for the patent was published on Nov. 7, under issue no. 45/2025.
According to the abstract released by the Intellectual Property India: "The present invention provides a protocol for the development of doubled haploids (DH) in plants belonging to the Poaceae family, preferably plants of Pennisetum genus, including but not limited to Pennisetum glaucum, through anther culture. Said protocol comprises use of selective and specific conditions and media composition including hormones for optimal DH plant production in large numbers. Said protocol is short and reliable for DH plant production from spikelet to anther initiation and incubation conditions for high frequency androgenesis in Poaceae plants such as pearl millet, thereby resulting in crop improvement and strengthening the germplasm of the crop. This enables the development of pure lines, i.e., anther to plant, within 65-90 days."
