Abstract	Grain yield, nitrogen and phosphorus accumulation and utilization efficiency varied considerably among spring wheat cultivars and strains grown in a field experiment conducted in Poland. The majority of highest yielding strains had high harvest index (HI), nitrogen and phosphorus harvest index (NHI, PHI), also high amount of accumulated nitrogen in grain. The lines KOC 1477/98, KOC 2361/98, CJ 179/98, RAH 1796 showing high utilization efficiency of nitrogen and phosphorus were characterized also by high values of other tested traits. The HEC 1428/98, KOC 2003/98, KOC 2245/98, KOC 2249/98 and KOC 3845/98 showed high utilization efficiency for both nitrogen and phosphorus. The RAH 2070/98 and KOC 3530/97 had high utilization efficiency of nitrogen, while the CJ 396/98 and HEC 1957/98 had high utilization efficiency of phosphorus. The strains were characterized by average values of plant and grain dry matter, the same was nitrogen and phosphorus accumulation in grain, accumulation of these elements in plant was average or low. We conclude that there is a possibility of selection of spring wheat lines that integrate high grain yield with high mineral nutrient utilization
