Sugarcane is a significant C4 crop that has a lot of potential to produce biofuels worldwide because its juice ferments readily to produce ethanol. The current study evaluated the juice quality, cane fibre, and biomass of 32 introgressed hybrids of Saccharum and Earianthus with co-canes. Analysis of variance has revealed presence of highly significant difference among Saccharum and Earianthus introgressed hybrids for all the traits studied. From the analysis, it was unravelled that IA 3135 (145.60 t/ha), 038701 X Co 62174-2 (142.82 t/ha), 94GUK-2454(141.90 t/ha) and GUK 00-1226 (141.67 t/ha) recorded 145.60, 142.82, 141.90 and 141.67 tons/ha of total harvestable biomass. Clones IA 3135, GUK 00-1226, 94GUK-2454 and 07-3284 recorded 19.65, 21.50, 18.95 and 19.35 per cent of juice brix at 360days coupled with high harvestable biomass of 145.60, 141.67, 141.90 and 139.35 tons/ha. A wide range of variation in quality, harvestable biomass, and cane fibre was found in the set of Saccharum and Erianthus introgression hybrids, according to the study. These hybrids can be used as energy cane for cogeneration purposes or as a special cultivar under sub-marginal management practices to take advantage of the twin traits of quality and biomass.
