Mutation variability and marker trait inheritance in hybrid-mutant populations F₂M₂ of winter wheat

Cytology and Genetics 2004, v 38, number 6, 13-18

Influence of hybrid seed treatment with mutagenes on genetic variability in hybrid populations of the second generation of winter wheat has been investigated. Treatment with mutagenes in moderate doses results in deviation of segregation of marker traits as compared to control towards either increase or decrease of the ratio of recessive allels. It was shown that in crossing combinations with red-ear form as one of the parental components, treatment with gamma rays at the dose of 100 Gy leads to significantly larger deviations of disintegration comparing to control.
