Abstract: In an experiment, 16 early maturing sugarcane clones along with 2 checks were planted in Randomized Block Design with three replications during spring season 2016-17 at Dr. RPCAU, Pusa, Bihar to study the genetic parameters for productive traits in early maturing sugarcane clones and select the superior clones. The productive traits under studied were germination percentage at 45 & 90 days after planting (DAP), number of shoots at 120 & 240 DAP (000/ha), plant height at 150 days, 240 days (cm) & 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 & purity per cent at 8 & 10th months stage, respectively, CCS per cent, cane and sugar yield (tonne/ha) at harvest. Analysis of variance revealed that highly significant differences among the clones for all the productive traits 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 traits. The traits namely, 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. On the basis of per se performance of six productive traits the clones namely, CoP 15437, CoP 14436 CoP 11437, CoLk 12207 and CoP 12437 were selected as superior early maturing genotypes. All these clones can be utilized by the farmers as well as Sugar Factories to get high yield and high sugar in early phage of crushing and also its can be further utilization for sugarcane crop improvement programme.
