Abstract

Promising sugarcane genotypes numbering fifteen were evaluated in the field for their tolerance to drought. The reduction in individual leaf area, leaf number, leaf area index and tiller population was significant due to treatment. Number of millable canes was significantly less in drought treatment (67,770/ha) as compared to the control ( 82,200/ha). Cane yield was reduced by 37% in drought treatment. Mean sugar yield was 9.96t/ha in control, while in drought it was 5.59t/ha. Among the genotypes evaluated Co 95003, Co 95005 and Co 95006 recorded higher cane and sugar yield even under drought treatment indicating their resistance potential.
