To study the genetic variation in the productive traits of early maturing sugarcane clones an experiment was conducted with planting of 15 early maturing sugarcane clones including two checks in Randomized Block Design with three replications during spring season 2017 at research farm of RPCAU, Pusa, Samastipur Bihar, Analysis of variances revealed that all the eighteen traits viz., germination % at 45 days after planting, number of shoots at 120 days, plant height (at 150 days, 240 days and at harvest), cane diameter at harvest, millable canes at harvest(000/ha), single cane weight at harvest(kg), brix, pol, purity and CCS (%) in juice at 8 and 10th month stage, CCS t/ha(sugar yield) and cane yield(t/ha) at harvest were found differed significantly for all the genotypes. The range of variation was conspicuous for cane yield, sugar yield, number of millable canes, germination% at 45 days, number of shoots at 120 days and plant height at 150, 240 days and at harvest. Phenotypic coefficient of variation (PCV) were higher than its genotypic counter parts for all the traits. High heritability coupled with high genetic advance as percent of means was observed for plant height at 150 DAP, single cane weight at harvest and sugar yield at harvest. High heritability coupled with moderate genetic advance as percent of means was observed for germination % at 45 days after planting, plant height at 240 days after planting, plant height at harvest, cane diameter at harvest and brix at 10th month stage. Moderate heritability coupled with moderate genetic advance as percent of means was observed for number of shoots at 120 days after planting and cane yield at harvest (t/ha).Therefore the traits viz, germination % at 45 days after planting, plant height at 150 & 240 days after planting, plant height at harvest, cane diameter at harvest, brix at 10th month stage, single cane weight at harvest and sugar yield at harvest cane be utilized for further sugarcane breeding programme
