Yield stability of wheat genotypes for northern western plains zone of India
In this investigation 23 genotypes of wheat were tested for stability in 19 locations of North Western plains of the country, Yield data generated from the trials were analysed using AMMI analysis. The distribution of genotype by AMMI revealed that the genotypes 10,13, 20,12,15 and 14 scattered clos...

| description | In this investigation 23 genotypes of wheat were tested for stability in 19 locations of North Western plains of the country, Yield data generated from the trials were analysed using AMMI analysis. The distribution of genotype by AMMI revealed that the genotypes 10,13, 20,12,15 and 14 scattered close to the origin, indicating minimal interaction of these genotypes with environments. 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. |
