F1 hybrids were produced using the German spring wheat variety Remus as a female parent and eight Croatian wheat varieties six winter and two spring types as male parents. The heterosis MP-mid parent, BP-better parent for five yield components was investigated in eight cross combinations. Data are based on field trial. All the combinations tested gave average heterosis MP, BP for 1000-grain weight 14.38%, 6.12% and grain weight per spike 11.47%, 3.68%. The highest heterosis MP, BP was found for 1000-grain weight 35.27%, 28.42% in the hybrid Remus-Sivka and for grain weight per spike 20. 45%, 19.1% in the hybrid Remus-Dukat. These data showed that the spring wheat variety Remus could be used in cross combinations for improvement of yield through higher 1000-grain weight and grain weight per spike.
