Abstract: A field trial was conducted at Nuclear Institute of Agriculture (NIA), Tando Jam, during the season of 2010/2011 and 2011/2012. Twenty nine sugarcane genotypes (13 soma-clones and 16 exotic clones) were evaluated in a randomized complete block design with four replications. Ten important agronomic characters were measured out of which three were cane yield contributing traits and seven were quality parameters. Statistically significant differences were observed for all the characters among genotypes. Clone CP92-1198 (exotic) and somaclone NIA-1026P3 had shown substantial superiority for cane and sugar yield (t/ha). Low values of coefficient of variations exhibited accuracy of experiment. Quality and quantitative traits showed strong negative correlation, causing selection breeding difficult in sugarcane.
Key words: Saccharum officinarum, Somaclones, Exotic clones, Correlation, quantitative and qualitative traits.
