Figure 2. The sucrose/hexose ratio in selected internodes from four high and four low commercial cane sugar (CCS) clones from (a) the introgression population (IJ76-514 x Q165) and from (b) eight clones from the backcross population (KQ99-1410 x Mida). Each point is the mean ± SE of three measurements. Internode middle denotes that position midway between internode 10 and the bottom of the stalk.
