Assessment of Genotype X Environment Interaction and Stability of Promising Sugarcane Genotypes for Different Agronomic Characters in Peshawar Valley

Sugarcane germplasm screening and testing for superior attributes is a regular feature of the breeding program at Sugar Crops Research Institute, Mardan, Khyber Pakhtunkhwa, Pakistan. Sixteen genotypes which were in the final stages of selection were evaluated in three different environments for Genotype by Environment (G x E) interaction and stability performance. Combined analysis of variance showed highly significant variances for Environments (E), Genotypes (G), and their interaction (G x E). The effect of environments was very pronounced for all the characters highlighting their importance in the performance of genotypes. None of the genotypes was stable across the three environments for all characters. However, genotypes Mardan 93 and CP 77/400 showed a comparative stability for cane yield (t/ha)
