Abstract
Cilj ovog rada je analizom proizvodnje sjemena različitih genetskih osnova utvrditi reakciju linija na klimatske uvjete, točnije na količinu i raspored oborina, jer je pretpostavka da je relativna vlaga zraka u pozitivnoj korelaciji sa visinom prinosa i kakvoćom sjemena. Istraživanje je provedeno u dvije različite godine (2013. i 2014.) gdje je analizirana proizvodnja sjemena dva OS hibrida kukuruza na površinama Poljoprivrednog instituta u Osijeku. Analiza vremenskih prilika bazirana je na srednjim vrijednostima temperatura zraka i količini oborina na istraživanom području tijekom vegetacijskog razdoblja kukuruza u razdoblju od 2013.-2014. godine, te na višegodišnjim prosječnim vrijednostima za razdoblje 1981.-2011 godine. Analiza prinosa hibrida kukuruza pokazuje da je u odnosu na 2013. godinu, 2014. godina bila signifikantno bolja. Prinos sjemena hibrida OS 617 bio je viši u odnosu na hibrid OS 602 u klimatski nepovoljnijoj (sušnoj) 2013. godini za 40,45 %, dok je u klimatski povoljnijoj godini prinos sjemena hibrida kukuruza OS 617 bio viši u odnosu na hibrid OS 602 za 38,46 %. U 2013. godini ostvaren je prosječan prinos zrna od 1,98 t/ha za oba hibrida. Najmanji prinos zrna dao je hibrid OS 602 (1,59 t/ha), dok je hibrid OS 617 imao prinos od 2,67 t/ha. Najrodniji hibrid u 2014. bio je OS 617 (3,78 t/ha), dok je manji prinos ostvario hibrid OS 602 (2,73 t/ha). Prosječni prinos u 2014. godini iznosio je 3,25 t/ha i kao takav bio je viši od prinosa u 2013. godini

The aim of this work is the analysis of the production of seeds of different genetic basis to determine the response line on climatic conditions, in the amount and distribution of precipitation, because the assumption is that the relative humidity is positively correlated with the amount of yield and quality of seeds. The study was conducted in two different years (2013 and 2014) where was analyzed seed production of two OS maize hybrids on the area of the Agricultural Institute in Osijek. Analysis of weather conditions was based on the average values of air temperature and rainfall in the study area during the growing season of maize in the period from 2013th to 2014th year, and the long-time average values for the period 1981.- 2011 year. Analysis of maize hybrids shows that, compared to 2013, 2014 was significantly better. Grain yield of hybrid OS 617 was higher compared to the hybrid OS 602 in unfavorable weather conditions (drought) 2013 to 40.45%, while in the favorable climatic year grain yield of hybrid OS 617 was higher than the hybrid OS 602 for 38.46% . In 2013 average yield of 1.98 t/ha for both hybrids was achieved. The smallest grain yield gave a hybrid OS 602 (1.59 t/ha), while the hybrid OS 617 had a yield of 2.67 t/ha. Yielding hybrid in 2014 was the OS 617 (3.78 t/ha), while hybrid OS 602 (2.73 t/ha) had lower yield. The average yield in 2014 was 3.25 t/ha and, as such, was higher than the yield in 2013.
