Twenty spring bread wheat genotypes were evaluated for yield and yield component relationships at two locations in the Arusha Region of Tanzania. Correlation coefficient and path-coefficient analyses on yield components revealed that both seed size and number of seeds/ear had direct and strong effects on grain yield. Similarly, seed size greatly influenced test weight. On the contrary, ears/m2 showed a negative relationship with the number of seeds/ear, test weight and grain yield
