This chapter deals with induction of haploidy via parthenogenesis in Persian walnut and via microsporeembryogenesis in almond and hazelnut. Haploid induction through in situ parthenogenesis using pollinationwith irradiated pollen to stimulate the embryogenic development of the egg cell, followed by in vitroculture of the immature haploid embryos. Microspore embryogenesis allows the induction of immaturepollen grains (microspores), to move away from the normal gametophytic developmental route in thedirection of the sporophytic one, yielding homozygous organisms (embryos in this case). Unlike other fruitcrops (such as Citrus), regeneration of entire plants has not yet been obtained in our studied nut crops;however, it gives the methodology should be used to continue the roadmap.
