The present investigation was carried out with eighteen clones including four water logging tolerant checks. The experiment was conducted at the Sugarcane Breeding Experimental Block of Norman Borlaug Crop Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar, India. Genetic variability was studied for 14 different morphological and quality characters. Analysis of variance revealed significant differences among all the clones for all characters studied. Highest PCV was exhibited by number of tillers (16.60%) followed by germination (15.63%). The lowest PCV (3.43%) was observed for juice sucrose. The analysis of heritability and genetic advance indicated that morphological characters viz. juice extraction percent, cane height, number of tillers, germination percent, NMC and cane thickness recorded moderate to high estimates, suggesting that selection of morphological traits would be effective for developing improved water logging tolerant clones.
