A new mutation in pearl millet, Pennisetum typhoides (Burm.) Stapf and C. E. Hubb that suppresses virtually all shoot‐epidermis trichomes is described. Hairs on blade and sheath, barbs along leaf margins, short hairs and claws on veins of upper and lower leaf surface, cilia on ligules, hairs on nodes, wooly hairs below base of panicle, rachilla hairs, and scabrous and pennate properties of bristles are suppressed. The plumose stigmas are modified into fork‐like stylar branches by the gene. Hair tufts at the apex of anthers, which have taxonomic significance, are absent. The trait is recessive and is inherited as a single gene pair.
