Four autotetraploid male R. nigromaculata were crossed with female R. brevipoda for the purpose of obtaining numerous amphidiploids. The reproductive capacity of the amphidiploids was examined. Experiments involving the matings of male and female amphidiploids, and the production of allotriploids by mating male or female amphidiploids with male or female diploids are described. The production of amphidiploids from female amphidiploids by gynogenesis accompanied by refrigeration of eggs is also described.
