Understanding the nature of the root system will help the plant breeder in selecting superior varieties that are adapted to different soil conditions. An experiment using ten high yielding sugarcane varieties was conducted to determine the root characteristics and yield performance in sandy soil of Pampanga, Philippines. The experiment was laid-out in RCBD with four replications. ANOVA revealed significant differences in 16 out of 18 parameters. Phil 8013, Phil 7544, Phil 97-3933, Phil 99-1793, Phil 04-0081, Phil 00-2569 and Phil 03-1727 produced significantly highest sugar yield (LKg/ha) which ranged from 223.05-257.93. Root density (RD) (g) and distribution at different soil depths from 0-100cm with interval of 10cm were 318.35 (46.47%), 132.36 (21.59%), 81.02 (14.05%), 26.24 (4.57%), 14.77 (2.61%), 14.58 (2.53%), 13.23 (2.32%), 11.53 (2.05%), 10.80 (1.93%) and 10.63 (1.87%). Stalk characteristics such as diameter, length and number of millable stalks and RD at 0-10cm, 11-20cm, 21-30cm, 51-60cm, 61-70cm, 71-80cm and 90-100cm were positively correlated with cane yield while percent brix and purity were positively correlated with sucrose content.
