Using xenia in the breeding of rye hybrids

Abstract

The object of research were: hybrid grains F1 of winter rye resulting from the topcross of nine yellowseed inbred lines with two testers Madar and Krótka I, and six hybrids F1 of spring rye resulting from topcross of six Turkish yellowseed populations with the tester SMH-02. The aim of the analysis was to confirm the degree of crossing ability and the effect of xenia of 1000 grains weight. The possibility to breed initial materials characterized by a high combining ability by means of xenia was stated. Xenia of 1000 grains weight allows to elaborate a new technology of hybrid seed production of rye.
