Compensatory Effect of the Gene in Semi-Dwarf Spring Triticale (x Wittmack).

The dwarfness in many triticale cultivars is provided by the dominant () allele found in rye. However, along with conferring semi-dwarf phenotype to improve resistance to lodging, this gene also reduces grain size and weight and delays heading and flowering. () genes are plant-specific transcription factors that regulate plant growth, including stem growth, in terms of length and thickness, and leaf and fruit size.
