Abstract

Anthers of 10 alfalfa (Medicago sativa L.) lines were used as initialmaterial for the production of androgenic haploids. More than 30 variants of nutrient media were tested. Twenty five different treatments with low temperatures and gamma rays were tried in order to find optimal conditions for callus induction and organogenesis. The genotype, stage of microspore development, phytohormonal composition of the nutrient media and pretreatment with physical agents, alone or in combination, affected the efficiency of organogenesis and regeneration in anther cultures of alfalfa. Plants exhibited a high degree of variability in their chromosome number. Haploids, dihaploids and mixoploids were obtained. Cytological studies of in vitro pollen development revealed the origin of the regenerants from microspores.
