Regeneration of Shoots on Root Explants of Flax

Regeneration of shoots from adventitious root explants of flaxwas achieved for two of five cultivars tested. Root explantsof the cultivar Bombay regenerated buds on MS medium with varioussupplements, the best combination being 002 mg I^–1 NAA,1 mg I^– 6-BA, 20 mg I^– adenine and 500 mg I^–cefotaxime. Adenine, in the presence of 6-BA, and cefotaxime,in the presence of both 6-BA and adenine, were found to stimulatebud initiation, but the most important factor influencing budregeneration from flax roots was genotype
