Allelic Variation of and Genes in Winter Durum Wheat and Its Effect on Quality Parameters.

Winter durum wheat is a relatively young crop that is highly adaptable due to its winter type of growth habit. The priority of breeding and genetic improvement of winter durum wheat is to improve grain quality and pasta quality, largely determined by the glutenin storage proteins. In the present study, a collection of 76 accessions of winter durum wheat from P.

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.
