Abstract Culture conditions for triticale (X Triticosecale Wittmack) androgenesis were studied using microspore culture. Sporophytic development of isolated triticale microspores in culture is described in five winter hexaploid triticale genotypes. Microspores were isolated using a microblendor, and embryogenesis was induced in modified 190-2 medium both in the presence and absence of growth regulators. The highest induction of microspore embryogenesis was obtained in a growth regulator-free medium. Adventitious embryogenesis was observed during in vitro development of triticale microspores. Albino and green plantlets were regenerated from embryo-like structures. More than 50% of regenerants were albino. In total, 126 green plantlets were produced, transplanted and established in soil. Cytological evidence revealed that 90% of the transplanted regenerants were haploid.
