• NS soybean cultivars were assessed for variability of and correlations between yield components and the effect of genotype - environment interaction on yield, yield component and morphological characteristics. Experiments were carried out at Rimski Sancevi experiment field in 2009 and 2010. The following characteristics were evaluated: plant height (cm), height of first pod (cm), 1000-grain weight (g), grain yield (kg/ha) and the combined content of oil and protein in grain (%). Combined contents of oil and protein in grain soybean were determined by a non destructive method of near infrared spectroscopy on PERTEN DA 7000 (NIR/VIS Spectrophotometer). The studied characteristics varied significantly depending on genotype and year. The highest yield of 5273 kg/ha was obtained in 2009 with the genotype Victoria. Highest 1000-grain weights, 2009-2010, were achieved with the genotypes Valjevka and Victoria (149.27 g and 147.23 g). Maximum heights of first pod (19.40 cm) were recorded for the genotype Victoria, 2009-2010. Highest protein contents were obtained with the genotypes Valjevka and Victoria, 2009-2010, were and highest oil contents (21.73%) with the genotype Tea. Protein content was positively significantly correlated with 1000-grain weight and negatively significantly correlated with oil content, and negatively correlated with yield and the height of first pod. Oil content was positively correlated with the height of first pod. Thousand-grain weight was negatively highly significantly correlated with oil content in grain and negatively significantly correlated the height of first pod. The results of this study should facilitate further soybean breeding for improved seed yield and protein and oil contents. U radu je proucavana varijabilnost i medjuzavisnost komponenti prinosa i interakcija genotip spoljna sredina kod NS sorti soje. Istrazivanje je izvedeno na Oglednom polju u Rimskim Sancevima tokom 2009. i 2010. godine. Ispitivana su sledeca svojstva: visina biljaka (cm) i visina prve mahune (cm), masa 1000 zrna (g) i prinos zrna soje (kg/ha) i sadrzaj ukupnih proteina i ulja u zrnu (%). Sadrzaj ukupnih proteina i ulja u zrnu soje odredjen je metodom infracrvene spektroskopije na aparatu PERTEN DA 7000, (NIR/VIS Spektrofotometar) nedestruktivnom metodom, na principu NIR (Near Infra Red) tehnike. Sva proucavana svojstva signifikantno su varirala u zavisnosti od genotipa i godine. Najveci prinos 5.273 kg/ha u 2009.oj godini dao je genotip Victoria. Najvecu masu 1000 zrna imali su genotipovi Valjevka i Victoria (149,27 gr i 147,23 gr) u obe godine. Najvecu visinu prve mahune imao je genotip Victoria (19,40 cm), 2009.- 2010. Najveci sadrzaj proteina imali su genotipovi Valjevka i Victoria, dok je najveci sadrzaj ulja imao genotip Tea (21,73 %). Sadrzaj proteina bio je u pozitivnoj statisticki znacajnoj korelaciji sa masom 1000 zrna, a u negativnoj statisticki znacajnoj korelaciji sa sadrzajem ulja, i negativnoj sa prinosom i visinom prve mahune. Sadrzaj ulja bio je u pozitivnoj korelaciji sa visinom prve mahune, a u negativnoj ali statisticki visoko znacajnoj korelaciji sa masom 1000 zrna. Masa 1000 zrna bila je u negativnoj statisticki znacajnoj korelaciji sa visinom prve mahune. Ova istrazivanja predstavljaju osnov za dalje oplemenjivanje soje, poboljsanog prinosa semena i sadrzaja proteina i ulja.
