The sequence of histological events occurring during somatic embryogenesis from Sorghum bicolor genotype IS 3377 (pigmented variety) immature inflorescence were studied. Sections were made and studies were carried out from the initiation of callus induction to somatic embryogenesis. The Processes leading to embryogenesis were studied elaborately. Our observations indicated that somatic embryos arose from floral primordium region of embryogenic callus. Internal divisions gave rise to detached groups of cells on the callus surface. The transverse section of immature inflorescence segment showed central inflorescence axis was enclosed with peripheral floral primordia that appeared as protuberances of meristematic cells, richly dividing cytoplasmic cells at the tip of each floral primordium.
