A case of male sterility is reported in yellow sarson. The male-sterile mutants were morphologically similar to normal plants with regard to vegetative characters. But a significant reduction was observed in petal and anther size in the case of male-sterile plants.
Investigations on the mode of inheritance of male sterility have suggested that it is a monogenic recessive character. Its practical utility and theoretical implications are also discussed.
