Zusammenfassung:Aim. The nature of inheritance of morphological traits in simple and backcross hybrids F1
 and F2 of spelt with bread wheat
 was investigated. Methods. Field and laboratory methods for studying the inheritance of morphological characteristics
 in hybrids F1
 and F2
 . Results. It was confirmed that for simple hybrids of different wheat species, the morphological
 characteristics of plants, including spike shape, hull, spinous and plant height inherited monogenic. Additive effect of
 spelt and wheat genes, which determine the spikelet number, leading to its significant increase in ear was discovered. In
 backcross hybrids, with domination of the genome of other wheat species, the deviation from the theoretically expected
 traits splitting was observed. Conclusions. It was established that the increase in the number of spelt genes in the backcross
 hybrid increases the differences with wheat and make values of spike characteristics closer to the spelt.
 Keywords: Triticum spelta L., T. aestivum L., morphological characteristics, genetic analysis.
