he genetic studies were conducted on six new winter wheat (Triticum aestivum L.) line during three years investigations developed in agro ecological conditions of Kosovo. Data for various morphological and yield traits were taken and analyzed for spike length (SL), plant height (PH), total dry matter (TDM), spike Weight (SW), grain weight per spike (GWS), yield (Y) and harvest index (HI). Field design consisted in a randomized blocks design (RBD) with three replications. Results indicated that the line 01KS as the most competitive genotypes produced significantly higher for SL (9.58 cm), GWS (2.37 g per spike) and grain yield (10.66 t ha-1) while lower yield was recorded at the line 04KS (8.02 t ha-1). The lowest SL (8.4 cm) belonged to line 06KS which was ranked as the least competitive genotype. The significantly higher total dry matter (TDM) was recorded at the wheat line 02KS on value 4.88 g, while the lowest (4.44 g) belonged to 04KS which was ranked as the last genotype. There was a positive and significant harvest index (HI) on value from 50.5% to 39.1%.
