Abstract
AbstractAn attempt was made to transfer male‐sterility, mslc, from the Cornerstone mutant of tetraploid wheat to diploid wheat. The N‐banding technique revealed that chromosome 4 A of tetraploid wheat does not pair with chromosome 4 of diploid wheat in triploid F1 hybrids: consequtntly the transfer of male‐sterility gene(s) from tetraploid wheat to diploid was not successful. The culchiane induced ampliploids possessing AAAABB in mslc background were fully fertile indicating the complete compensation of mslc by the newly introduced A genome of T. monocaccum. The fertility compensating gene(S) presumably located on chromosome 4 of diploid wheat may be used to produce hybrid wheat by the XYZ system.
