abstract = "Cilj ove studije je bio da se ispita stepen varijabilnosti osobina četiri inbred linije suncokreta i njihova međuzavisnost primenom korelacione analize. Tokom 2018. i 2019. godine, na lokalitetu Bijeljina, Bosna i Hercegovina, umnožene su 4 inbred linije suncokreta: L-1 (SU), L-2 (SU), L-3 (IMI), L-4 (IMI) vlasništvo Instituta za ratarsto i povrtarstvo iz Novog Sada. Ponavljanja su napravljena na taj način što je jedna kaseta parcele (odnos redova A-sterilnog analoga i B-fertilnog analoga u jednoj kaseti je 6:2) predstavljala jedno ponavljanje, a broj ponavljanja iznosio je četiri. Rezul tati dvogodišnjih istraživanja u poljskim uslovima pokazali su statistički visoko značajne razlike, ispitivane inbred linije suncokreta razlikovale su se u prosečnim vrednostima klijavosti semena, mase 1000 semena, sadržaja ulja u čistom semenu i prinosa semena. Najveći koeficijent varijacije ostvaren je kod prinosa semena (CV=46,4 %), a najmanji kod sadržaja ulja u čistom semenu (CV=6,37 %). Klijavost semena u 2018. godini kod ispitivanih inbred linija u proseku je bila veća za 8 % u odnosu na 2019. godinu. Iste godine inbred linije su ostvarile veći prinos semena u proseku za 196 kg ha-1. Veća masa 1000 semena i sadržaj ulja u čistom semenu u proseku ostvaren je u 2019. godini, masa 1000 semena u proseku bila je veća za 7,67 g, dok je sadržaj ulja u čistom semenu bio veći za 0,75%, što statistički nije bilo značajno (p=0,063). Povećanje sadržaja ulja u čistom semenu prati statistički značajno povećanje masa 1000 semena (r=0,401), ali sa povećanjem prinosa semena, visoko statistički značajno se smanjio sadržaj ulja u čistom semenu, što je predstavljalo najjaču negativnu korelaciju (r=-0,434)., The aim of this study was to examine the degree of variability of traits of four inbred sunflower lines and their interdependence using correlation analysis. During 2018 and 2019, at the location of Bijeljina, Bosnia and Herzegovina, 4 inbred sunflower lines were multiplied: L-1 (SU), L-2 (SU), L-3 (IMI), L-4 (IMI) owned by the Institute of Field and Vegetable Crops in Novi Sad. Repetitions were made in such a way that one plot cassette (ratio of rows of A-sterile analogue and B-fertile analogue in one cassette was 6:2) represented one repetition, and the number of repetitions was four. The results of a two-year study of field conditions showed statistically highly significant differences, the examined inbred sunflower lines differed in the average seed germination, 1000 seeds weight, oil content in the pure seed and seed yield. The highest coefficient of variation was achieved in seed yield (CV= 46.4 %), and the lowest with the oil content in pure seed (CV = 6.37 %). Seed germination in 2018 in the examined inbred lines was on average 8 % higher than in 2019. In the same year, inbred lines achieved a higher seed yield by an average of 196 kg ha-1. Higher weight of 1000 seeds and oil content in the pure seed on average was achieved in 2019, weight of 1000 seeds on average was higher by 7.67 g, while oil content in the pure seed was higher by 0.75 %, which was not statistically significant (p=0.063). The increase in oil content in the pure seed is accompanied by a statistically significant increase in the weight of 1000 seeds (r=0.401), but with increasing seed yield, the statistically significant decrease in oil content in the pure seed, which was the strongest negative correlation (r=-0.434).",
