title: Microspore-derived haploid, diploid and triploid plants in Petunia violacea lindl.
abstract: Haploid, diploid and triploid plants in Petunia violacea have been produced by culturing anthers of early binucleate pollen on kinetin supplemented basal medium. Cytological studies reveal that non-haploid embryoids developed due to nuclear fusion at early stages of pollen embryogenesis. The significance of plants of various ploidy levels in this commonly cultivated species of Petunia is discussed.
