By removing the Rf multi locus from chromosome 1BS of wheat via chromosome engineering we were able to generate a resource for the production of male sterile wheats in three new cytoplasms. Cytoplasmic male sterility is an essential component in the development of many hybrid crops. In wheat (Triticum aestivum L.) only the cytoplasm of T. timopheevi(More)
In order to break the current grain yield barriers, breeders require genetic variation. Breeding for resistance to abiotic stresses may lead to better plant survival and improved grain yield. Exploring landraces may expand the genetic diversity of modern wheats. Five Turkish bread wheat landraces and 14 modern durum and bread wheat cultivars were evaluated(More)
Wild crop relatives are of considerable interest in plant breeding and significant efforts have been made to transfer their genetic variation into modern crops. Of the three diploid progenitors of bread wheat (Triticum aestivum L.), only Aegilops tauschii Coss. has been explored and exploited and only for some above ground characteristics. The three wild(More)
