Inheritance of yield-related morphological characteristics in F1 tobacco hybrids

The aim of this work was to study the mode inheritance number leaves per stalk and length, width area from middle part - traits directly related yield in offspring first generation. studies were made with four mother parent tobacco varieties different types (three Prilep type: P-23, ? 18-50/4, 76/86 one Basmak type ?? 8/1), pollen donor Burley B-1-91, their F1 hybrids. crosses 2018, 2019 2020, experiment genotypes hybrids set up 2019, 2020 2021, on a field trial at Scientific Tobacco Institute randomized block design replications. All appropriate cultural practices applied during growing season. research data indicates that there no heterosis for studied traits. partially dominant is an indicator good successive selection individuals future generations quick fixation stabilization MS 8/1 B-1/91 P 18-50/4 represent very interesting material breeding activities.
