Abstract
Fourteen bread wheat varieties were used in a line x testers analysis (10 lines and four testers) to obtain 40 F₁’s hybrids to study (i) The potentiality of heterosis expression for grain yield and its components traits under normal (80 kg N/fed) and low (40 kg N/fed) levels of nitrogen fertilization. (ii) The magnitude of both general and specific combining ability effects in F₁ hybrids under normal and low levels of nitrogen fertilization. (iii) Estimation of genetic components i.e heritability, additive and dominance variances under normal and low levels of nitrogen fertilization
