Spontaneous macromutants "soft wheat" or a complete homolog of Tritcum kiharae Dorof. et Migusch

For the successful development of breeding, a genetically diverse source material is necessary. The decline in genetic diversity is a global problem affecting most cultivated crops, including wheat. In this regard, the creation of a homologous soft wheat form for the second phylogenetic branch is very attractive, since it will be a valuable source material for the selection improvement of Triticum aestivum L.. AuBD. Previously derived from T. kiharae Dorof. et Migusch., AbGD under the influence of N-HMM (nitrosomethyl urea), the complete homologue showed phenomenal both phenotypic and certain genotypic similarity to soft wheat and easily crosses with the varieties of the latter. Later, the homologous form of soft wheat obtained from it under the influence of colchicine, despite its phenotypic proximity to the latter, looked like an intermediate form. Spontaneous macromutants "soft wheat" are shown, isolated, in the first case, from T. kiharae plants that have previously changed color, and, in the second, from the so-called intermediate form. The identified soft wheat macromutants were significantly superior in their production characteristics to the original T. kiharae and can also be used as a starting material to improve the characteristics of T. aestivum.
