Abstract

In 2008–2012 four groups of winter triticale hybrids were obtained and evaluated for male fertility: 16 F1 hybrids obtained from crossing 8 male sterile lines having T. timopheevi cytoplasm with 2 cultivars, 36 F1 hybrids from crossing 4 lines, each with a different cytoplasm (T. timopheevi, Pampa, Ae. sharonensis, and Ae. ventricosa) with 9 cultivars, 21 hybrids (F1 to BC4 generations) of 7 lines with three cytoplasms (T. timopheevi. Pampa, Ae. sharonensis) and 55 hybrids F1–BC3 with Ae. ovata cytoplasm. The hybrids displayed various male fertility level. The restoration index was from zero to 100% depending on the maternal line, the cytoplasm and the male parent genotype. In each group of hybrids with T. timopheevi, Pampa, Ae. sharonensis and Ae. ventricosa cytoplasm an interaction of female  male parent was found. All the hybrids with Ae. ovata cytoplasm were male sterile. The plant material obtained in these studies makes it possible to develop male sterility systems with Ae. sharonensis and Pampa cytoplasms, different from that with T. timopheevi cytoplasm.
