Figure 1. Sucrose concentrations in selected internodes on a fresh mass basis for (a) four high and four low commercial cane sugar (CCS) clones from the introgression population (IJ76-514 x Q165) and (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. FW, fresh weight.
