Abstract

On the experimental field of the Center for Small Grains in Kragujevac in the two growing seasons 2018/19 and 2019/20. it was analyzed plant height, lodging resistance and grain yield of 10 genotypes of winter wheat (L-25/6, L-56/98, L- 56/7, L-63/7, L-49 / 4, L-23/24, L-246/2, L-191 / 5-9, L-191 / 5-4 and L-36-2). The average annual temperature and precipitation in both growing seasons were above the multi-year average. The highest average yield during two years had the line L-191 / 5-9 (6,485 t ha-1), then L-246/2 (6,415 t ha-1), and the lowest line L- 63/7 (5,846 t ha -1). Wheat genotypes differed in plant height, so the L-23/24 line had the highest value for this trait in both growing seasons, and the L-25/6 the lowest. In the first vegetation season, a slightly higher plant height ranged from 76 cm to 96 cm, and in the second from 72 cm to 90 cm. All genotypes had good lodging resistance in optimum environments.
