Sixteen early maturing sugarcane clones were planted in Randomized Block Design with three replications during spring season 2016-17 at Dr. RPCAU, Pusa, Bihar to study the genetic variability for cane yield and its component traits in early maturing sugarcane. The characters studied were germination percentage at 45 and 90 days after planting (DAP), number of shoots at 120 and 240 DAP (000/ha), plant height at 150 days, 240 days (cm) and 300 days(at harvest), cane diameter (cm), fibre per cent, single cane weight (kg), number of millable cane (000/ha), juice quality traits viz., brix, pol and purity per cent at 8 and 10th months stage, respectively, CCS per cent at harves, cane and sugar yield (tonne/ha) at harvest. Analysis of variance revealed that highly significant differences among the clones for all the characters under study. Maximum range was found for the trait plant height at 150 days followed by plant height at 240 days and cane yield. The phenotypic coefficient of variance was greater than genotypic coefficient of variance for all the characters under study. The characters like cane yield, sugar yield, single cane weight, number of shoots at 120 DAP, cane diameter and germination percentage at 90 DAP showed high heritability coupled with high genetic advance as per cent of mean. Hence, the characters namely, cane yield, sugar yield, single cane weight, number of shoots at 120 DAP, cane diameter and germination percentage at 90 DAP can be utilized for further selection and genetic improvement of early maturing genotypes.
