Description The present study comprising 35 selected clones of sugarcane was
conducted in RCBD with two replications during 2012-13 at Zonal
Agricultural Research Station, V.C. Farm, Mandya.
The analysis of variance indicated the presence of significant
variability among the genotypes for all traits studied from plant canes
and pooled data. NMC, cane yield and CCS yield exhibited moderate GCV
and PCV coupled with high heritability and genetic advance in both cases
indicating the role of additive genes for the expression of these traits,
hence, phenotypic selection could be effective in improvement of these
traits. Cane yield and CCS (t/ha) had significant positive association with
tillers, NMC, cane length and single cane weight. The NMC exhibited
highest direct effect on cane yield in plant cane and pooled data.
Comparative analysis on sugar related traits indicated, VCF-0814-05 and
VCF-0707-05 for per cent Brix and VCF-0814-05 and VCF-0842-08
clones for per cent pol were found superior over the standards, none of
the genotype was found superior over the standards with respect to the
cane and sugar yield.
Eight clusters were formed on grouping of clones based on
Mahalanobis D2 distances. The results indicated that cluster VII and VIII
involved highly diverse genotypes can be chosen for isolating desirable
clone combinations.
Assessment of ratooning ability indicated that the clones VCF-
0710-01 and VCF-0602-03 excelled in performance for ratooning ability
than the checks. Discriminant function analysis for cane and CCS yield
recognised that there was sizable improvement in the target characters.
