Three mid-late clones of sugarcane viz 2007A177, 2007A126 and 2007A161 along with four standards viz 83V15, Co 7805, Co 86249 and Co 7219 were evaluated in main yield trials during 2011–12 and 2012–13 at Regional Agricultural Research Station, Anakapalle, AP. The mean data obtained from two plant and one ratoon crops in the experiment on number of millable canes (NMC), cane yield, per cent juice sucrose, commercial cane sugar (CCS) yield, stalk length, stalk diameter, single cane weight and germination per cent were statistically analysed and compared. The results revealed that the clone 2007A177 recorded significantly higher cane yield (112.86 tons/ha), CCS yield (15.29 tons/ha), juice sucrose (18.57%), stalk diameter (3.06 cm) and single cane weight (1.17 kg) compared to the best standard 83V15 (102.44 tons/ha, 13.49 tons/ha, 18.22%, 2.43 cm and 1.13 kg respectively). The clone 2007A161 recorded highest NMC of 99.23 thousand/ha while the clone 2007A126 recorded the highest stalk length of 3.09 m and highest germination (63.83%). The clone 2007A177 was found to be resistant under nodal and plug methods of inoculation against the prevailing red rot races with intermediate reaction (MR) against Cf 997 and moderately susceptible to smut.
