Abstract

interactions. To obtain information about the reaction of winter wheat
genotypes to different environmental conditions experiments were set in
2006/2007 with 24 winter wheat genotypes in two seeding rates (SN) at 300
and 600 seeds/m2 in four replications in randomized complete block design at
four locations with different soil types (Osijek-eutric Cambisols, Tovarnikchernozem,
Nova Gradiška, alluvium and Požega, pseudogley-soil type).
Grain yield, 1000 kernel weight, test weight and protein content were
analyzed. Significant differences were obtained in all traits between
genotypes (G), locations (L) and sowing rates (SN) and interactions GxL and
LxSN, and for test weight between interaction GxSN. With higher grain
yield the most stable genotypes were Alka, Sana and Osk.89/05 at both
seeding rates and Osk.48/07 at 300, and Ficko at 600 seeds/m2. In both
seeding rates highest grain yield (78.79 dt/ha; 73.05 dt/ha) and test weight
(82.1 kg/hl; 81.8 kg/hl), but with the lowest protein content (11.4%, 11.3%)
were recorded at location Tovarnik. The lowest grain yield in seeding rate at
600 seeds/m2 and the highest protein content in both seeding rates (14.1%,
14.4%) were recorded at location Osijek. At location Nova Gradiška was the
lowest grain yield at 300 seeds/m2 and the highest 1000 kernel weight at both
seeding rates. The lowest test weight and 1000 kernel weight at both seeding
rates were recorded at location Požega. Best yielding genotypes were Lucija,
Osk.48/07, Zlata, Srpanjka and Renata. The highest test weight had
genotypes Felix, Lela, Osk.63/05, Renata and Super Žitarka and the highest
1000 kernel weight had Osk.63/05, Super Žitarka, Renata, Felix and
Osk.64/05. The highest protein content had genotypes Divana, Golubica,
Žitarka, Osk.63/05 and Osk.77/05. All genotypes had the higher yield and
test weight in seeding rate at 600 seeds/m2. Generally, there is a tendency to higher protein content and less 1000 kernel weight in seeding rate at 600
seeds/m2. However, specific reactions of individual genotypes can be
recorded.
