After mutagenic treatment with NMU (nitroso‐methylurea) flower buds and flower‐bud pedicels of broccoli were cultivated in vitro. Among regenerated MJ plants, one male sterile, but female fertile mutant was found, for which a monogenic dominant inheritance of male sterility was demonstrated. A scheme to utilize dominant controlled genie male sterility in Brassica oleracea for hybrid breeding is discussed.
