Abstract In the a B. Campestris, cc B .oleracea and their ac f \ hybrid plants, studies were made to assess the retained chromosome affinity between their a and c genomes and the ability of the different combinations of these related genomes to undergo regular cytological behavior in the induced tissue cultures of the three genotypes. In additions the percentage of crossability between the two species and their biochemical relationships by enzyme electrophoreses were examined. The study aiso included the examination of the effect of two more Factors other than genomic constitution on initiation, growth dynamics and Cytological behavior of tissue culture and plant regeneration (i.e.explant types and media type) The f ,hybrid planed were obtained by reciprocal conventionnnal crossing methods . The research work and the obtained results are as follows. |
