Abstract
The genetic control of plant height has been studied in hexaploid forms of triticale (2n = 42) with genomic structure AABBRR. Thirty-four specimens from the world collection of triticale at the Vavilov All-Russian Research Institute of Plant Breeding with plant heights from 70 to 180 cm have been used in the study. The hybrid analysis of the first, second, and third generations, as well as backcross offsprings, has demonstrated that the given trait is characterized by different modes of inheritance: dominance of dwarfism, dominance of tallness, and intermediate inheritance. It has been found that triticale cultivars of middle and large height differ from short ones in alleles of one or two major genes.
