In vitro Plant Regeneration in Mungbean (Vigna radiate (L.) Wilczek)

Abstract

An efficient regeneration protocol without the intervention of callus using cotyledon explants of three mungbean varieties namely, BARI mug-3, BARI mug-5 and BINA mug-5 was developed. Best response toward multiple shoot regeneration in BARI mug-5 and BINA mug-5 was observed on MS supplemented with 0.5 and 0.5 mg/l Kn. However, for BARI mug-3, MS supplemented with 0.5 mg/l BAP and 0.1 mg/l Kn was found to be most effective for multiple shoot regeneration. Half-strength of MS supplemented with 0.5 mg/l IBA was found to induce healthy roots from the excised shoots in all the three mungbean varieties. In vitro regenerated plantlets with well developed roots were successfully established in soil.
