[Analysis of the segregation and recombination rates at morphological and SSR loci in hybrid combinations of barley substitution lines]

Abstract

The inheritance of nuclear morphological and molecular markers was studied in hybrid reciprocal populations of barley alloplasmic lines. A number of loci displayed a distortion of the Mendelian inheritance and a decrease in recombination rate depending on the cross direction and cytoplasm of parental forms. The segregations shifted towards both the mutant recessive and normal dominant phenotypes. The effect of cytoplasm on transmission and recombination of nuclear loci was shown.
