dc.description.abstractThe aim of this research was to examine variability, broad-sense heritability, genetic advance of plant height (PH), spike length (SL) and productive tillering (PTC) of 30 genotypes of bread and durum wheat, and correlations between them. Field trials were carried out during 2010-2011 and 2011-2012 growing seasons at the three sites: Rimski Šančevi, Zemun Polje and Padinska Skela. Results of this investigation showed that genotype was the most significant source of variation for SL in bread and durum wheat with 67.1% and 54.4% of explained sum of squares (SS) and for PH in bread wheat with the 66% of SS. Environment represented the most important source of variation for PTC in bread and durum wheat wheat with 68% and 35.9% of SS and also for PH in durum wheat with 51.6% of SS. The ratio of genetic and genotype × environment interaction (σ² g / σ² ge )components of variance indicated more stability in bread wheat for PH and SL and less for PTC in both wheat species. Broad-sense heritability (h²) was very high (>90%) for PH and SL in bread and durum wheat, but smaller for PTC (80.7% and 75.6%, respectively). Considering the high obtained values of h² and high expected genetic advance as percent of mean for PH and SL of bread wheat and for PTC of durum wheat the success of selection for desired trait values can be predicted. PH proved to be correlated with PTC at three environments(0.538, 0.532, P lt 0.05, 0.708, P lt 0.01).en
dc.description.abstractCilj ovog istraživanja je bio da se prouči varijabilnost, heritabilnost u širem smislu, genetička dobit za visinu biljke (PH), dužinu klasa (SL) i koeficijent produktivnog bokorenja (PTC) 30 genotipova hlebne i durum pšenice, kao i korelacije među njima. Poljski ogledi su bili postavljeni tokom 2010-2011. i 2011-2012 vegetacione sezone na tri lokaliteta: Rimski Šančevi, Zemun Polje i Padinska Skela. Rezultati ovog istraživanja su pokazali da je genotip bio najznačajniji izvor variranja za SL hlebne i durum pšenice sa 67,1% i 54,4% objašnjene sume kvadrata (SS) i za PH hlebne pšenice sa 66% SS. Ekološki faktori su predstavljali najznačajniji izvor variranja za PTC hlebne i durum pšenice sa 68% i 35,9% SS, kao i za PH durum pšenice sa 51,6% SS. Odnos komponenti varijanse-genetičke i interakcije genotip × sredina (σ² g / σ² ge ) je ukazala na veću stabilnost hlebne pšenice za PH i SL, i manju za PTC, za obe vrste pšenice. Heritabilnost u širem smislu (h²) je bila veoma visoka (> 90%) za PH i SL hlebne i durum pšenice, dok je za PTC bila niža (80,7% i 75,6%). Uzimajući u obzir dobijene visoke vrednosti za h² i očekivanu genetička dobit izraženu u procentima proseka za PH i SL hlebne pšenice i za PTC durum pšenice, može se očekivati uspeh selekcije za očekivane vrednosti proučavanih osobina. PH je bila korelisana sa PTC u tri sredine (0,538 i 0,532, P lt 0,05, 0,708, P lt 0,01).sr
