Genetic variability of the progenies (30 per mating group) ofSaccharum officilJQrum crossed
with S. barberilsinense, S. robustum, S. spontaneum and commercial hybrids were studied.
The maximum genetic variability was observed among progenies of mating group
involving S. sp01ltaneum for all the characters except cane length and cane yield. The mean
performance of progenies involving commercial hybrids was the best for cane diameter,
single cane weight, quality characten and sugar yield. The S. officinarum x commercial
hybrids mating group was found advantageous for obtaining promising clones as
compared to othergroups. The valuesofcorrelation coefficients between various characters
of cane yield and quality characters varied among the four mating groups. The selected
genotypes could be used to create a broader genetic base in sugarcane breeding.
