Androgenesis in plants refers to :

  • A.development of androecium
  • B.development of anthers
  • C.development of haploid embryo from microspores or pollen in vitro
  • D.Initiation of androecium

Answer: C

Androgenesis is the development of haploid embryo from microspores or pollen in vitro.

In anther or pollen culture, immature pollen grains are switched from their normal path to pollen development and divide to form embryos or callus, giving haploid plants from the male gametophyte. Guha and Maheshwari first produced such plants from Datura anthers in 1964; doubling the chromosomes then gives homozygous lines.

Development or initiation of the androecium and the anthers is ordinary flower development, not androgenesis.
