Inheritance of hypocotyls colour in aposigothic sugar beet generations (Beta vulgaris L.).

Abstract

It was investigated the autosegregation on the basis of coloring of hypocotyls in 31 apomixis genitures of sugar beet. The part of unpainted (green) seedlings in the studied selections varied from 0 to 26,5 %. The studied genitures fall into 7 segregation groups, connected with distinctions in doses of prepotent and recessive alleles of a locus Рр defining production of pigments in fabrics of sugar beet. The greatest share of unpainted seedlings is marked out in genitures of plants with yellow pith of a root, the smallest – in root genitures with white pith of a root.
