In a field experiment sixteen sugarcane clones including two checks were planted with three replications in RBD at Paddy Block, RAU, Pusa, Samastipur, Bihar during 2012-13 under low land area where its grand growth phase coincides with water-stagnation depth 40-45 cm for three months to study the variability, heritability and genetic advance of Sugarcane clones under water-logging condition for the traits viz, Germination Percentage at 45 days, Number of Shoots at 120 days, Plant Height at 150, 240 and 360 days, Cane diameter, NMC, Single Cane weight, Red Rot Score, Brix at 10,11 and 12 month, Pol at 10, 11 and 12 month, Purity at 10, 11 and 12 month, CCS Per cent at harvest and Cane yield. Highly significant variation was observed for all traits except purity at 10 and 11 month stage and CCS percent at harvest. High heritability coupled with high genetic advance as per cent of mean found for traits viz. number of shoots at 120 days, plant height at 240 and 360 days and single cane weight which will in favor of direct selection. Highest GCV and PCV were recorded for number of shoots at 120 days followed by plant height at 240 days and plant height at 360 days, indicating the importance of these traits to evaluate for water-logging tolerance. Comparatively the maximum phenotypic and genotypic variance were exhibited by the traits viz. plant height at 360 and 240 days, number of shoots at 120 days, plant height at 150 days, number of millable canes and cane yield (t/ ha).Number of shoots at 120 days, plant height at 240 days, plant height at 360 days, and single cane weight showed high heritability coupled with high genetic advance. Hence, direct selection can be done through these characters for future improvement of varieties.
