Some results of work on production of isogenic lines, mutants and distant hybrids in wheat

Abstract

Increase wheat yields by improving its genotype – one of the most urgent problems of the rural economy. At present, using traditional methods of selection and genetic studies, such as backcross selection, distant hybridization, experimental mutagenesis, increased efficiency of obtaining genetically modified and improved forms of wheat. Fertility rates of soft wheat hybrids with wild species (Т. timopheevii,) depends on the direction of crossing and genotypes of varieties. Wild species as the parent component positively affect the high percentage of grain fertility. Genome of Nadezhda variety is compatible with genomes of wild species.
