Evaluation of sugarcane genotypes for theoretical yield of alcohol

Seventy seven genotypes of sugarcane were evaluated in second clonal stage for theoretical yield of alcohol. The genotypes viz., 2010T-72 (14.67 g/100ml), 2010T-16 (14.01 g/100ml) and 2010T-88 (13.93 g/100ml) showed significantly higher performance over the best check Co 7219 (12.80 g/100ml) for theoretical yield of alcohol. Path analysis revealed that the characters viz., total sugars per cent, pol per cent cane and CCS per cent exhibited positive direct effects on theoretical yield of alcohol and the other characters also exhibited their indirect positive effects on theoretical yield of alcohol via total sugars per cent, pol per cent cane and CCS per cent, indicating that these were the major contributing characters to theoretical yield of alcohol in sugarcane.
