The experiment has included seven genotypes and three check varieties. The observations were collected for fifteen characters i.e.Number of shoots at 240 days, Germination percentage at 45 days, Number of tillers at 120 days, NMC at harvest, Single cane weight, Cane yield at harvest, Stalk length at harvest, Stalk diameter at harvest, Brix % at harvest, Sucrose % at harvest, Purity % at harvest, CCS% at harvest, Fibre % at harvest, Pol % at harvest, CCS ton/ha.Significant high difference has been found among the genotypes for all the characters for Analysis of Variance.The character sucrose % at harvest exhibited high heritability and the character cane yield exhibited high genetic advance as per cent of mean. Many characters i.e. Germination % at 45 days, Number of tillers at 120 days, Number of shoots at 240 days, NMC at harvest, Single cane weight, Cane yield at harvest, Stalk length at harvest, Stalk diameter at harvest exhibited positive correlation with CCS ton/ha, thus selection based on these characters will result in improvement of sugar yield and characters like i.e.Germination % at 45 days, Number of tillers at 120 days, Number of shoots at 240 days, NMC at harvest, Single cane weight exhibited positive correlation with Cane yield, thus selection for this characters increase the cane yield.CCS % and Cane yield at harvest had highest positive direct effect with CCS ton/ha.All ten genotypes are clustered in four groups, where cluster II contain maximum number of genotypes.Maximum and minimum cluster distance were recorded between cluster II and IV and I and II respectively.Maximum intra cluster distance was observed between cluster I.Cluster II exhibited highest mean value for number of shoots at 240 days, single cane weight, stalk length at harvest, CCS % at harvest and cluster III exhibited highest mean value for brix % at harvest, sucrose % at harvest, fibre % at harvest and cluster IV exhibited highest mean value for Germination %, Number of tillers, NMC at harvest, Cane yield and Stalk diameter at harvest.EnglishThesis
