Projekat

Razvoj novih sorti i poboljšanje tehnologija proizvodnje uljanih biljnih vrsta za različite namene (MPNTR - 31025)

Sažetak

Analiza mega-sredina suncokreta sprovedena je prema podacima prinosa zrna 20 hibrida i 19 test lokaliteta tokom 2006. i 20 hibrida i 16 test lokaliteta tokom 2007. Kombinovani podaci obuhvatili su 15 hibrida i 9 test lokaliteta, zajedničkih za obe godine istraživanja, pri čemu je analizirano kao izbalansirani eksperiment. Analiza komponenti varijanse pokazala je da interakcija hibrid puta lokalitet objašnjava 2,74, 5,8 i 3,72 puta više varijacija nego hibrid na prinos zrna za 2006. i 2007. u kombinovanim podacima, tim redom, i ukazuje na potencijalno postojanje mega-sredina. Naši rezultati su pokazali postojanje dve mega-sredine u reonima gajenja suncokreta u Srbiji: (1) Kula Vitovnica, Aleksa Šantić, Sombor i (2) Rimski Šančevi, Kikinda. Zaključeno je da ako želimo da perspektivni hibridi suncokreta budu optimalno iskorišćeni, moraju biti drugačije obrađeni za dve utvrđene mega-sredine.
