Variability and inheritance of tillering in barley hybrids

Five divergent genotypes of two-rowed winter barley (Vada, Djerdap, NS-293, Jagodinac and Sladoran) have been selected for diallel crossing in order to study the mode of inheritance, the gene effect and the components genetic variance for the productive tillering in F1 and F2 generation. The variabi...

Zusammenfassung:Five divergent genotypes of two-rowed winter barley (Vada, Djerdap, NS-293, Jagodinac and Sladoran) have been selected for diallel crossing in order to study the mode of inheritance, the gene effect and the components genetic variance for the productive tillering in F1 and F2 generation. The variability of investigated trait differed. Different modes of inheritance (partial dominance, dominance and overdominance) and partial dominance were found in the F1 and F2 generation, respectively. The genetic variance components, average degree of dominance and regression line indicated partial dominance in the inheritance of tillering. The range of the obtained values of heritability for the tillering was found to be very wide.
