Abstract

The androgenic ability of four Medicago sativa L. genotypes (Boynitza5, Byala, 494, and 3815) was tested. Callus and organogenesis were induced in all lines studied. The percentage of anthers producing calluses and organogenesis showed wide variation (calluses-from 11% up to 77%; organogenesis-4.8% to 15.2%). It has been established that genotype, nutrient medium composition, and stage of pollen development considerably affected both callus production and organogenesis. Androgenesis in M. sativa could be achieved via callus and direct embryogenesis. About 500 morphologically different regenerants were obtained. Wide variability in chromosome number of regenerated plants was observed by cytological studies. Haploid, dihaploid, as well as mixoploid plants wereobtained.
