About genetical nature of mutation in spring soft wheat plants

The character of inheritance of morphological and quantitative determinants in mutants of spring soft wheat, obtained as a result of treatment of chemical mutagens and infection of barley shaded mosaic virus was evaluated. It was shown, that mutations determining the bearded and white corn seeds were monogenic and recessive, but mutations of quantitative determinants were both dominant (more often) and recessive. A growing conditions have a great effect on manifestation of determinants and character of their inheritance in mutant forms. Chromosomal nature of mutations of economically important determinants was revealed.
