Polyembryonic caryopses that give rise to twin and triplet seedlings have been found in several inbred lines of pearl millet. Near-equal and unequal twins, fused and non-fused coleoptile types, and identical and non-identical triplets were encountered. Some evidence for the inheritance of polyembryony was accumulated. Inbreds differed markedly in frequency of polyembryonic caryopses, but thermal-neutron radiation, ethyl methane sulfonate, and diethyl sulfate treatment of the seed were not conclusively shown to increase the frequency of twin and triplet seedlings. Triploid and tetraploid types were recovered from the diploid pearl millet.
