Genotype-environment interactions for protein content in wheat (Triticum aestivum L.) were studied by growing 21 genotypes (homogeneous as well as heterogeneous) in eight environments. The genotypes interacted significantly with the environments created at two locations. Artificially created environments at one location had non-significant effect on protein content, whereas locational effects were pronounced. Both the linear as well as non-linear portions of genotype-environment interactions were found to be important. Widely adapted genotypes ‘C 306’ and ‘Kalyansona’ also showed high stability for protein content over environments. Stability of protein was not found to be related to either homogeneous or heterogeneous populations.
