Abstract
The current research “Evaluation of early maturing sugarcane genotypes
for yield and quality traits”was conducted to analyse the variability among all the
genotype of sugarcane in the Kanyanpur farm of DR.RPCAU,Pusa. 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.
