Analysis of yield components of F1 hybrids of crosses betwen spring and wheat types Triticum aestivum L.
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.
