Abstract
In this paper, fertility of flowers in spikelets, 1000 grains weight and protein content in grain were investigated in strains and cultivars of wheat: Lanca, CZR 1334, triticale: Presto, CZR 1277 and rye CZR 1. Random blocks method was used with three replications. Kernels were machine-sown in 10 m2 plots. Thirty ears from each plot were randomly harvested. Fertility of the first and second flowers in wheat, triticale and rye were similar. Fertility of the 3rd and 4th flowers was significantly higher in wheat in comparison with triticale and rye. The highest 1000 grains weight characterized the 1st and 2nd flowers of spikelets in triticale. Protein content in grains from each spikelet were similar. The highest protein content in grain was found in triticale CZR 1277 and rye CZR 1.
