Abstract
Elimination of sugarcane grassy shoot disease (SGSD) through apical meristem culture technique for producing clean planting material of sugarcane has been attempted in the present study. The results showed that meristems length of 2 and 3 mm were free from the SGSD pathogen at higher frequency than larger meristem length of 4 mm. However, the frequency of survival of explants during initiation of shoot cultures was higher in larger meristems (60%) in comparison to smaller ones (40%). The micropropagated plantlets raised from meristem culture were confirmed for disease-free by nested polymerase chain reaction (PCR) analysis at monthly interval up to 6 months. This is the first report on the elimination of SGSD phytoplasma through meristem culture in India.
