| Popis: | Genotype by environment interaction (GEI) reduces the association between phenotype and genotype which result in relative ranking and stability differences of genotypes across environment. The objectives of this research were (i) to select sugarcane genotypes of high yield and stable (ii) to study the interrelationships among various parametric and no parametric stability statistics. Seventeen experimental genotypes and three check cultivars of sugarcane were evaluated at seven environment using randomized completely block design. Methodologies based on analysis parametric (Regression-bi-S2di, Shukla variance, Ecovalence-W, Coefficient of variation-CV, index of Lin and Binns-PI and AMMI value) and non-parametric statistics (Nassar and Huehn- Si(1), Si(2), Si(3), Si(6), Kang-RS, Fox-TOP, and Thennarasu- NPi(1) , NPi(2), NPi(3), NPi(4)) were used for Ton of Pol per hectare (TPH). Genotypes and environment showed high significant difference (P |
