Abstract: The present investigation was undertaken to identify the stable cultivars across different environmental condition. Sixteen early maturing and elite genotypes of sugarcane were evaluated for their adoptability in respect of cane yield and its components for three years from 2004-2007 under two plants and one ratoon crops. The stability of genotypes was estimated by using the method of Eberhart and Russell In this analysis sum of square due to G x E were portioned into individual genotypes (X-i), regression of environmental means (bi) and deviation from regression (S2d). The regression coefficients (bi) and mean square deviation from regression (S2d) were used to define genotype stability. Significantly mean square differences among Genotypes x Environment for all the characters were observed, this is indication of significant variability among the experimentation. The mean square due to G x E were significant for NMC, length of internode, sucrose % in juice and CCS%. Higher mean values for sucrose percent in juice were found in the genotypes CoS05263, CoS05249 and CoS05259 was superior to others. The stability parameters for NMC, cane yield, sucrose % and CCS% shown by the genotype CoJ64 compared to UP05233, CoS05266, CoS05260, CoS05276 and CoS05263 indicated better adoption and less sensitive to environmental changes. From the present study it is concluded that for cane yield and sucrose % in juice in UP05233 and CoS05263 performance better then rest of elite genotypes study due to having high mean values of genotype over all three environments. Therefore, these genotypes may be commercially cultivated over a wide range of environments.
