Experiment was carried out to test the performance of new promising sugarcane clones series 2008 under rainfed conditions. The objective was to evaluate yield potential and quality of 19 promising sugarcane clones compare with 6 checked cultivars, U-Thong 3, Suphanburi 80, Khon Kaen 3, LK92-11, K84-200 and K99-72at Nakhon Sawan Field Crops Research Center during Mar 2011- Jan 2012. The trial was laid out in RCBD with 2 replications. Plant cane of 25 cultivars/clones was evaluated. Cane yield and yield attributing characters i.e. cane height, number of internode/cane, number of plant/stool and number of millable cane were recorded. Juice quality viz percent juice extraction and commercial cane sugar (%CCS) in juice were determined at harvesting. Significant (P≤0.01) differences were observed for CCS, sugar yield etc, excluding cane yield, No. of plant/stool and % fiber The results obtained from plant cane only showed that the presence of genetic variability among the genotypes and their differential response to rainfed conditions. NSS08 20-1-5, NSS08 33-1-11 and NSS08 191-20-1 showed the best performances in both cane 22.65, 20.92 and 20.67 tons/rai, respectively) and sugar yields (3.03, 3.40 and 3.23tons/rai, respectively) which were about 43, 30 and 32 % higher in cane yield than U-Thong 3 and 26, 35 and 42 % higher in sugar yield, respectively. These promising clones will be further evaluated for yielding and ratooning ability
