Production of Vieus-Free Sugarcane by Tissue Culture
Abstract
Sugarcane plants of the three commercially varieties namely F140, Q83 and Supan I were produced free from sugarcane mosaic virus by the apical meristem culture. Shoot tips, 0.2-0.5 mm. in size, were cultured on MS medium supplemented with 3 mg/L 2,4-D and 15% (v/v) coconut water. Yellowish-white callus developed within 2 months. Plantlets were regenerated from calli cutured on MS medium with 1 mg/L 2,4-D and 15% (v/v) coconut water. The suitable medium for root induction in all cultivars was the MS or MS with 1 mg/L IBA. Detection of sugarcane mosaic virus (SCMV) in plantlets or individual plants by ELISA showed negative result suggesting that they were virus free.
