An experiment was conducted to evaluate salinity tolerance of promising sugarcane genotypes with microplot techniques at Agricultural Research Station, Perumallapalle, ANGRAU, Andhra Pradesh during 2018-19. Nine sugarcane genotypes along with four checks were studied for salinity tolerance with two treatments viz., control and salt treatment. Soil EC of 6 dS m -1 was developed in salt treatment with external addition of salt water. Results revealed that the mean germination, single cane weight, sucrose and commercial cane sugar (CCS) were significantly differed by genotypes. The control treatment recorded higher mean germination (65%), single cane weight (1.062 kg) and sucrose (17.44%) than salt treatment (54%, 1.000 kg and 15.83%, respectively). Among genotypes Co 86032, 2012 T 58, 2012 T 72 showed less reduction in germination, 2012 T 81, Co 86032, 2012 T 58, 2012 T 72 and 2012 T 58 recorded less reduction in cane weight under saline conditions. The genotypes Co 86032, 2012 T 72 and 2003 V 46 showed maximum K/Na ratio than other genotypes. Consider these parameters, 2012 T 58, 2012 T 72, 2012 T 180 and Co 86032 genotypes showed salt tolerance.
