dc.description.abstractMany authors showed the possibility of developing highly yielding and stable hybrids. The assumption was that commercial maize hybrids were characterized not only by the level of average yield bat also by their stability. Fifteen commercial maize hybrids of medium late and late FAO maturity groups (400-700) were used in the present study. The two-year four-replicate trials were set up in six locations according to the randomized complete-block design. Stability parameters were determined after the method of EBERHART and RUSSEL (1966), in which the genotype was considered stable if it had a high average yield, a coefficient of regression of approximately 1.0 and deviation from regression as small as possible. The obtained results show that early maturity hybrids responded better to more modest growing condition and had a greater deviation from regression, while late maturity hybrids had a coefficient of regression closer to unity and they generally better responded to improved growing conditions.en
dc.description.abstractMnogi autori su pokazali mogućnost stvaranja prinosnih, a istovremeno stabilnih hibrida. Pretpostavljeno je da se komercijalni hibridi kukuruza razlikuju ne samo po prosečnom prinosu već i po stabilnosti. Petnaest komercijalnih ZP hibrida kukuruza, srednje ranih, srednje kasnih i kasnih FAO grupa zrenja (400-700) je bilo uključeno u ovo ispitivanje. Ogled je bio postavljen u šest lokacija, dve godine i četiri ponavljanja po kompletno randomiziranom blok dizajnu. Parametri stabilnosti su određeni po metodu EBERHART I RUSSEL (1966), po kojem se genotip smatra stabilnim ako ima visok prosečan prinos, koeficijent regresije oko jedinice i devijaciju od regresije što je moguće manju. Dobijeni rezultati pokazuju da srednje rani I srednje kasni hibridi imaju veću devijaciju od regresije i daju bolji odgovor u lošijim sredinama, dok kasni hibridi imaju koeficijent regresije blizu jedinice i generalno daju bolji odgovor na poboljšanje uslova gajenja.sr
