Morphological study euploid and monosomic wheat-rye hybrids

The influence of male and female genotypes, the effects of their interactions, the influence of 1D,3D,4D and 5B chromosomes and the effects of their interaction were studied in 30 F1 wheat-rye euploid and aneuploid hybrids /2n=28,27,A B D R/ concerning 7 morphological characters: heading date, common tillering, productive tillering, culm length, last internode length, ear length and spikelet number per ear.F1 hybrids were obtained by crosses between four hexaploid cultivars Triticum aestivum L.2n=42: Chinese Spring /CS/, Mironovka 808 /M 808/, Zlatka /ZL/, Novostepnyachka /N/, as well as their monosomic lines by 1D,3D,4D and 5B chromosomes with two inbred lines Secale cereale L.2n=14:Bulgarian Low Stem Rye /B L S R/ and Lozen 14 /L 14/.
