The origin of somatic embryos derived from rhizome explants of triploid Musa cv. Grand Nain was the subject of histological studies during different phases of ontogenetic development. The investigation revealed that the majority of somatic embryos showed normal root formation and consisted of highly vacuolated cells in the poorly structured shoot apex. The embryogenic mass and somatic embryos were mostly derived from several morphologically competent cells. Single cell origin depended on the presence of organogenetically functional vascular cells of rhizome explants and occurred infrequently. The implications of these findings for genetic improvement of banana and plantain by in vitro mutation breeding and gene technology are discussed.
