Abstract

Path coefficient analysis based on the results for 25 lines of semi-dwarf winter wheat showed high direct effects of 1000 grain weight, ear density, number of spikelets and number of grains per spikelet on plot grain yield. Significant simple correlation between yield and a number of spikelets per ear and a number of grains per ear was found. An analysis of ear variables can be used as an indicator in a selection program. Increases in grain number were associated with increases in 1000 kernels weight that varied according to severity of dwarfism and varietals background.
