Identifying the superior wheat genotypes in multi-environment trials by using modified superiority index [electronic resource].

Includes references.

Eleven wheat (Triticum aestivum L.) genotypes were evaluated under irrigation and water stress conditions in eight environments as follow: four environments in 2005/2006 at Kafr El-Hamam (El-Sharkya Governorate) and El Bostan (EL-Behera Governorate).While the other four environments were conducted during 2006/2007 and 2007/2008 at Experiment and Research Station, Faculty 0f Agriculture, Cairo University, (Giza Governorate). This study aimed 10 identify the yield stable genotypes across eight environments by using modified superiority index Genotypes, environments and their interaction had highly significant mean squares for grain yield. Mean performance of grain yield showed that" genotypes (L.R. 3, L.R. 7, L.R. 8 and L.R. 10) were insignificant compared with the cheek variety (Sahel 1). Genotypes yield stability across the testing environments using the modified superiority index proved that four genotypes (L.R. 3, L.R. 8, and L.R. 10 and Sahel 1) were stable in yield performance across the eight Environments.
