Research Abstract	Four tetraploid varieties and five diploid plants were used for the induction of haploid through psudo-fertilization in phalaenopsis orchids. Di-haploid plants obtained from tetrapoid. However, mainly diploid were obtained from diploid plants. One haploid was obtained from diploid plants. This is the first induction of haploid plant in phalaenopsis orchids.
