understanding of the relationship among sugar yield components could increase the efficiency of selection for sugar yield, once in recent decades, the increase in sugar yield has been achieved primarily by increasing cane yield rather than sugar content (Jackson 2005). Milligan et al. (1990) pointed that selection for increased sucrose content should emphasize cane yield with concentration on stalk number. Thus, the evaluation of the yield components as also as correlations between their components is an important step in the characterization of a sugarcane family.
The quality parameters Fiber%, Brix and Pol%Cane are the most relevant agronomic traits used as an indicator of sugarcane quality (Aitken et al. 2006).
