ABSTRACT

This research was carried out at the experimental plots of the Field of The Agronomy Faculty of The Azerbaijan State Agrarian University, during 2013-2017. We used as a parent material for 50 combinations of hybridizations. In the F1 populations belonging to the abovementioned combinations, plant height, spike height, spikelet number per spike, kernel number and kernel weight per spike and 1000-kernel weight were determined and the hybrid vigor was calculated. Positive and significant differences varying among the combinations were found in the F1 plants with higher values than the parent’s average (heterosis) as well as in F1 plants showing higher values than the superior parent (heterobeltiosis).

Keywords: Wheat, hybridizations, agronomic traits, hybrid vigor, spike.
