MALE sterility in Lathyrus odoratus L. was first recorded by Bateson, Saunders and Punnett¹. Male sterility was absolute and was inherited as a single recessive gene linked to light axil and cretin². Fabergé³ and Upcott⁴ reported that the sterility resulted from disturbances in the meiotic division following normal metaphase pairing. Such plants were normal and fully fertile on the female side.
