Abstract: A study was conducted to estimate the association among different traits on cane and sugar yield. Sixteen early maturing sugarcane clones were planted at Dr. RPCAU, Pusa, Bihar. The trial was laid out in Randomized Block Design with three replications during spring season 2016 to genetic studies on early maturing sugarcane for high sucrose and cane yield. The characters studied were germination percentage at 45 DAP, germination percentage at 90 DAP, number of shoots at 120 DAP (000/ha), number of shoots at 240 DAP (000/ha), plant height at 150 days (cm), plant height at 240 days (cm), plant height at harvest (cm), cane diameter at harvest (cm), fibre per cent at harvest, single cane weight (kg), number of millable cane at harvest (000/ha), brix per cent during 8 month stage, pol per cent during 8 months stage, purity per cent during 8 months stage, brix per cent during 10 month stage, pol per cent during 10 months stage, purity per cent during 10 months stage, cane yield (tonne/ha), CCS per cent at harvest and sugar yield (tonne/ha) at harvest. Characters like plant height at 150 days, plant height at 240 days, cane diameter, single cane weight, millable cane, plant height at harvest exhibited significant and positive association with cane yield. Characters namely, plant height at 150 days, plant height at 240 days, cane diameter, cane weight, millable cane, plant height at harvest, brix per cent during 10 month stage, pol per cent during 10 month stage and CCS per cent showed significant and positive association with sugar yield. Therefore, the selection can be practiced for these characters in order to identify the superior clones for improvement of cane and sugar yield in early maturing sugarcane
