THE MSIRI breeding program is widening its scope to exploit sugarcane biomass for alternative commodities such as fuel ethanol and electricity to ensure sustainable sugarcane production. In this context, seventeen amilies comprising different nobilised generations (F1, BC1, BC2) were evaluated in two contrasting environments, sub-humid and very humid, to identify crosses that can produce different types of canes. Most of the male parents were commercial-type clones chosen for incorporating enomes from S. spontaneum. Some 60 seedlings from each of 5 F1, 8 BC1 and 4 BC2 families were planted in each environment in randomised omplete block designs with three replicates of 20 progenies per block. The characters evaluated were stalk number, diameter, and height; quality characters were analysed from millable cane stalks. Families differed significantly for all characters within each group and environmental effects were prominent for the quality characters but were not consistent for the morphological traits within the different groups. Family x environment interactions were not important except for Brix and pol percent cane for the F1 group indicating that segregating seedlings need not be replicated in different environments at this stage.
