PLANT-REGENERATION FROM SHOOT APEX EXPLANTS OF FOXTAIL MILLET

Green and etiolated shoot apices of foxtail millet (Setaria italica L. ) cv. Nese 2A were cultured on Murashige and Skoog medium with four co ncentrations of 2,4-dichlorophenoxyacetic acid or 2,4,5-trichloropheno xyacetic acid. In all treatments, embryogenic calli capable of plant r egeneration were induced after ten weeks in culture. Calli induced on 2 mg l(-1) of 2,4-D from green apices gave a higher rate of plant rege neration in comparison with etiolated apices on the other treatments. Plant regeneration was obtained from one year-old cultures. Regenerate d plants were successfully established in soil, reached maturity and p roduced seeds.
