1. Male sterility with female fertility has been observed in nature in eight forms of the genus
2. Degeneration occurs rapidly and with regularity, either in pachytene or in the course of pollen development, at a stage which is characteristic for each form.
4. Male sterility has mainly been ascertained under experimental conditions, especially after induced self-fertilization. Under conditions of relative isolation, which favours its occurrence, male sterility serves as a mechanism for reducing self-fertilization.
5. In gynodioecious species, the production of “female” plants may often, originally, be determined by single genes for pollen sterility.
