Abstract	Harvest index in sugarcane based on sugar yield were studied in 30 sugarcane genetic stocks. Statistically significant differences of harvest index — sugar yield among clones, among stages and significant interaction between clone x stage were observed at 0.1% level. The wide variation of harvest index-sugar yield was between 0.061 in Co 62399 to 0.108 in CoC 671 at 10 months. Clones showing high harvest index was observed in CoC 671, B 37172, Co 62174, Co 418, Co 7704, CoA 7601, Co 7508, Co 7204, Co 678, Co 6806, Co 7717, and Co 997 and low harvest index was observed in Co 62399, CP 44-101, Co 1148, Co 617, CoJ 64, Co 62101, NCo 310, H 50-7209, Co 775, Co 419 and Co 975. Harvest index was increased from 0.081 at 10 months to 0.086 at 12 months. Harvest index-sugar yield had significant positive correlations with leaf N/S, N/Cl, N/Na, cations/anions, sheath N/S ratio, sheath cations minus anions, sucrose % juice and sugar yield – 8, 10 and 12 months, internodes numbers, cane volume, cane height, cane thickeness, cane wegith, harvest index — sugar yield at 10 and 12 months. There were significant negative correlations of harvest index-sugar yield with sheath N/P and N/Si ratios. Harvest index-sugar yield at 10 and 12 months had no associations with leaf N/K, N/P, N/Ca, N/Mg ratios, cations minus anions, sheath N/K, N/Ca, N/Mg, N/Cl, N/Na ratios and culm basic density.
