Sažetak
In diallel crosses (without reciprocals) of four genetically divergent wheat cultivars (Jugoslavija, Osijecanka, Zitnica, and NS Rana 2) the variability and inheritance of physiological nitrogen efficiency (PEN) in wheat plant were investigated. The mode of inheritance, gene effect, combining ability of parent cultivars and F1 and F2 hybrids for physiological nitrogen efficiency (PEN) were studied. The different mode of inheritance: partial dominance, dominance and overdominance for analyzed traits were established. On the base of genetic components of variance was estimated that non-aditive gene action have gene higher impact than additive in the inheritance of PEN. The best general combiner for PEN in both F1 and F2 generation was Zitnica cultivar. The combination Zitnica x NS Rana 2 in both F1 and F2 generation was the best for PEN.
