Na oglednom polju Centra za strna žita u Kragujevcu u dve vegetacione sezone 2018/19 i 2019/20 analizirana je visina stabla, otpornost na poleganje i prinos zrna 10 genotipova (linija) ozime pšenice (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 i L-36-2). Srednja godišnja temperatura i količina padavina u obe vegetacione sezone bile su iznad višegodišnjeg proseka. Najveći prosečan prinos tokom dve godine imala je linija L- 191/5-9 (6,485 t ha-1), zatim L-246/2 (6,415 t ha-1), a najniži prinos linija L-63/7 (5,846 t ha-1). U prvoj vegetacionoj sezoni zabeležena je nešto veća visina biljke i kretala se od 76 cm do 96 cm, a u drugoj od 72 cm do 90 cm. Najveću visinu stabla u obe vegetacione sezone imala linija L-23/24, a najmanju L-25/6. Svi genotipovi su imali dobru otpornost na poleganje.
