Parents of various origins and their diallel F2-hybrids were evaluated in field and pot experiments under varying levels of soil N. The range of additive variance in the components of N efficiency was narrow, especially under N shortage. The soil N-treatments imposed had a substantial influence on gene actions responsible for the efficiency components and modes of inheritance. Genotype×nutrition interactions were common. Under high N-fertilization, the efficiency components were inherited in a manner favourable for wheat selection (preponderance of additive effects). However, the enhanced contribution of non-additive gene effects and increased dominance under N-limited conditions could impede wheat selection to improve the N efficiency and adaptation to less luxurious fertilization regimes. Selection methods that eliminate masking non-additive influences and take advantage of the additive variance should be employed to improve these traits.
