Selection indices were constructed for four populations of sugarcane ( Sacchanim sp .) and for combined data from the four populations. The average selection indices from the combined data were applied to a test population. When selection for metric tons per ha of cane (THC) was based on stalk length, stalk diameter, and stalk number, expected genetic advance was 89.0% of that obtained when selection was based on THC itself. When selection was for metric tons per ha of sucrose (THS), inclusion of Brix in the index along with the above traits gave 92.1% of the expected genetic advance obtained for selection based on THS itself.
