Description
  • Five genotypes of hexaploid tritordeum (2n=6x=42, AABBHchHch) and one genotype of octoploid tritordeum (2n=8x=56, AABBDDHchHch) were tested for androgenic responsibility and regenerated capacity and compared with barley and wheat. In the experiments the time of the effect of cold pre-treatment (10, 20, 30 days at 4 oC ) and influence of two different media MN6 and modified C17 were observed. The androgenesis was induced in all tested genotypes of the tritordeum. The frequency of androgenic anthers ranged from 5.7 to 23.9% and the frequency of green regenerants ranged from 0.6 to 5.9% of cultured anthers. The highest regeneration rate, 7.6 green plants per 100 cultivated anthers, was reached at 20 days cold pre-treatment in octoploid tritordeum HT109. The modified medium C17 gave the higher frequency of calli and embryos formation, but more green plants regenerated on the medium MN6. Androgenic response and regeneration capacity of tritordeum genotypes were low in comparison to barley genotypes cultiva
