Amaranthus hypochondriacus L. was subjected to physical (gamma rays) and chemical (EMS and DES) mutagens. Though chlorophyll mutations were not very frequent, viable mutations affecting the leaves and the inflorescence were obtained in M1 and M2 generations. Among these, fasciation of the floral axis resulting in different patterns was more prominent. The significance of these fasciations from economic and phylogenetic stand points are discussed.
