The performance of potential wheat genotypes across diverse environments of Pakistan

Abstract

In Pakistan, wheat used as a staple food that provides necessary nutrients and has a wide adaptation in different environments. A set of 18 wheat (Triticum aestivum L.) genotypes were tested at 23 different locations (Environments) in all over Pakistan. The AMMI biplot analysis was used to identify the genotypes performance across the environments and Genotype Environment Interaction (GEI). The G5 and G6 genotypes performed excellent across the 23 environments, therefore their yield performance are stable at all locations of Pakistan during 2015-16. While, G4, G5, G11, G17 performed very well at all locations during 2016-17. The performance of G5 genotype remains stable in both year of study at all locations so we strongly recommend for cultivation in any region of Pakistan. The G1 (E13), G16 (E14), G11 (E2), G3 & G5 (E18), G14 (E15, E19), and G7, G10 (E10) these genotypes perform well in specific environment and so respective genotypes recommended for specific region where performance remains excellent. The selection of ideal environment in which performance of genotypes are excellent. The three environments (E4, E1 and E10) are best environment in which all genotypes perform very well during both years of study
