The pairing behaviour of the individual chromosome arms of Hordeum vulgare (Hv) with their homoeologous arms of H. bulbosum (Hb) at metaphase I of meiosis in tetraploid Hb × Hv hybrids and the frequencies of recombined Hv chromosome arms in selfed offspring were studied on differentially visualized chromosomes after fluorescent in situ hybridisation. The frequencies of paired Hv-Hb arms in the F2 and F3 hybrids were correlated with the frequencies of recombined Hv chromosomes in progenies.

Article Synopsis
  • Barley yellow dwarf virus (BYDV) significantly reduces yields in major cereal crops, prompting research into resistant varieties.
  • A resistant wild barley species, Hordeum bulbosum, was crossed with cultivated barley to transfer its resistance to BYDV into cultivated varieties.
  • The resulting offspring showed strong resistance linked to a dominant gene named Ryd4 (Hb), highlighting its potential for improving BYDV resistance in barley breeding programs.

Thirty-six percent of the wild potato (Solanum L. section Petota Dumort.) species are polyploid, and about half of the polyploids are tetraploid species (2n = 4x = 48).
