Abstract
The aim of writing this paper is to review production of haploids in orchids in vitro. Haploids possess half number of chromosomes and do not undergo fertilization. In vitro conditions provide necessary nutrients and conditions that are required for growth of haploid plantlets. The natural breeding cycle of orchids is very slow as well as unpredictable. To reduce this time, the technique of in vitro haploid production is used. In vitro conditions can decrease or shorten the time required for juvenile period in Orchids. Haploid plants are produced from in vitro haploid culture. This technique is useful to produce homozygous pure lines and to increase the yield of a plant.
Keywords: In vitro, haploid production, orchidaceae, orchid seeds, angiosperms, monocots
