Abstract: In this work,we summarize the brief history of in vitro androgenesis in pepper,with reviews of factors affecting haploid induction which containing growing conditions and donor plant genotype,microspore developmental stage,abiotic stresses and culture media and its supplements,cytological studies of in vitro androgenesis,practical application of haploid technique in Capsicum breeding. Finally,we outline the drawbacks of haploid technology for pepper breeding and potential solutions to overcome genotype dependency and high frequency of abnormal microspore-derived embryos in anther and microspore culture.

Key words: Capsicum, in vitro androgenesis, haploid, anther culture, microspore culture
