Seven release varieties of sugarcane (Saccharum officinarum L.) were evaluated for G X E interaction, adaptability with sustainability index and their comparison for cane yield (t/ha) incomplete randomized block design during spring season of 2015-16, 2016-17, 2017-18, 2018-19 & 2019-20 at Agricultural Research station, Ummedganj, Kota under South-Eastern Plane Zone of Rajasthan. The mean cane yield (t/ha.), regression coefficient (bi) and deviation from regression (S2d) with sustainability index was used to identify the stability and adaptability of popular sugarcane varieties. Pooled analysis of variance showed highly significant differences among environments, genotypes and genotype x environment (G x E) interaction. Sufficient mean square values due to G x E interactions indicated the varieties interacted considerably with the environmental conditions. Both linear and nonlinear components of G x E (linear) components were highly significant showing the importance in expression of traits. The linear component was significant as against the nonlinear component (Pooled deviation), which revealed that a large portion of G x E interaction was accounted for by the linear regression through pooled deviation was significant. Based on stability parameters and over all mean performance of cane yield, variety Co 0238, CoS 8436 and Co pant 97222 were identified as superior which were well adapted to all the environments, stable with above average yielding ability or highest. Cane yield with non-significant bi and s2d values coupled with high sustainability index. This showed that these varieties were better responsive to the favorable environments. Variety CoJ 64 & Co 05009 was responded favourable to better environments but give poor yield in unfavorable environments. Hence, they are suitable for favorable environments.
