Studied environments explained 57.2% of the total variation, whereas G and GxE captured 6.2% and 24.3%, respectively. First two principal components (PC1 and PC2) were used to create a 2-dimensional GGE biplot and explained 26.4% and 14.3% of GGE sum of squares (SS), respectively. Environments of Karnal, Ludhiana and Gurdaspur fall in same sector with genotypes 23 & 16. The spearman correlations calculated based on ranks by stability methods varied from positive value 0.97 to negative correlation of 0.759. The cultivar superiority estimate (Pi) maintained negative correlation with other estimates ranking. ER -
