Variation in Colletotrichum falcatum-Red Rot Pathogen of Sugarcane in Relation to Host Resistance

Sugar Tech Aims and scope Submit manuscript

Abstract

Variation in red rot pathogen Colletotrichum falcatum Went was studied in detail in relation to host resistance in 12 genotypes belonging to six sugarcane species viz., S. officinarum, S. barberi, S. sinense, S. robustum, S. spontaneum and Erianthus sp. In which the host resistance and sucrose content of different species have been correlated with pathogenic virulence. It was observed that S. officinarum genotypes had high brix than other species of Saccharum and allied genera. Cultural studies indicated that C. falcatum virulence related factors viz., growth, sporulation and conidial germination had negative correlation with the host resistance and positive correlation with sucrose content of various sugarcane species juice. Influence of unautoclaved host extract on pathogenic characters indicates that the factors other than sucrose content plays role in deciding the host resistance. Pathogenicity studies showed that there is selectivity in differentiating the host resistance of various species by C. falcatum pathotypes especially less virulent isolates reacted well in clones with low sucrose content. Hence selection of genotypes from different species depends on pathotype virulence and the selection must be from well reacted and distinguished isolates for effective screening.
