Abstract
The detection of new mutations in saffron flowers with increased number of stigmata has been reported, and the other mutants in floral whorls were discussed. Referable to the sexual sterility of saffron, it is concluded that if the observed mutations verified to be external stimuli determined; the cause which may be detected could increase saffron spice production and; reduce the cost of saffron production in the future. Mutagenic effects of carbon-ion beam on corms of saffron have been reported in this study.
