In Vitro Multiple Shoot Induction From Embryonic Axes of Annual Herbaceous Legume Faba Bean (Vicia faba L.)

Abstract

The faba bean (Vicia faba L.) is cultivated in the Mediterranean and Aegean regions only. It is a rich source of protein and an important source of food and feed for human and animal consumption. Faba beans have a narrow genetic base and their improvement through hybridization is not feasible because of high pollen self-incompatibility. This study was carried out using the embryonic axis of cv. Filiz99 and Eresen87 regenerated on MS medium containing 11 different combinations of BAP and NAA. The results showed 100% shoot regeneration frequency with maximum number of 3.3 and 3.5 shoots per explant on cv. Filiz99 and Eresen87 respectively. Regenerating shoots were rooted on 1 mg L-1 IAA. The in vitro regenerated shoots were continuously cultured for 3 weeks to acclimatize them. This approach could improve broad bean seed germination and subsequently regeneration. The results could also facilitate genetic transformation studies.
