Abstract
SummaryAutotetraploid has been obtained in Ammi majus L. by colchicine treatment. The autotetraploid showed slower rate of growth, smaller leaves, decreased number of branches and delayed flowering. Lesser number of inflorescences with poor fruiting and seed setting was also observed. Untreated plants had eleven bivalents (2n=22) while autotetraploid exhibited 22 bivalents (4n=44) at diakinesis and metaphase I. Abnormalities like univalents, rod bivalents and unequal separation of chromosomes were also observed.
