During 1996/97 growing season investigations of influence of different sowing rates (400, 500, 600 and 700 germinable seeds/m 2 ) on grain yield were done at new AG-cultivars of winter wheat (AG-5.12, Lara, Kruna and Lenta) and cultivar Žitarka as a control. Field trial was established on split-plot design with 4 replications and basic plot of 7,8 m 2 . By statistically analysis of investigation results it was concluded that different sowing rates have had not significant influence on grain yield. Investigated cultivars have showed statistically very significant influence on grain yield (P
