• The virulent nature of the pathogen and its ability to develop new pathogenic races has led to the breakdown of resistance in many popular cultivated varieties of Sugarcane. To assess resistance level, 142 C 2 generation clones along with five standards and two varieties were evaluated under artificial inoculation separately with inoculum of two prevalent races (CF08 and CF09) of the red rot pathogen by plug method. Disease reaction of the clones was recorded on 0–9 scale continuously for three seasons. Results revealed that a total of 39 clones exhibited resistant/moderately resistant reaction against both the races over the three seasons. Among these sixteen clones exhibited more than 18% sucrose along with more than 80 t/ha yield. The clones, PC-2013-14-114, PC-2013-14-120, PC-2013-14-135, PC-2013-14-144, PC-2013-14-175, PC-2013-14-180, PC-2013-14-186, PC-2013-14-187, PC-2013-14-221, PC-2013-14-224, PC-2013-14-231, PC-2013-14-505, PC-2013-14-539, PC-2013-14-547, PC-2013-14-552 and PC-2013-14-556, exhibiting better yield and sucrose along with resistance continuously for three seasons. Therefore, it is confirmed from the present study that the source of resistance against red rot is available in sugarcane varieties/lines in the form of hidden variability and it can be further manipulated and released through crossing programmes.
