Out of various selection indices constructed for sucrose content in sugarcane, using 41 genotypes, only the selection index including length of internode + brix per cent+purity per cent + CCS. per cent + sucrose per cent was found to be the best as expected genetic gain of 43.54 per cent over the straight selection was noticed. Hence, the selection for sucrose content in sugarcane would be more efficient when all these attributes are taken into consideration.
