“…Although aberrations are less tolerable in a tetraploid, and even less so in a diploid, Schlegel (1982) produced wheat chromosome additions to rye by backcrossing a wheat-rye hybrid several times with rye. Thiele et al (1988) subsequently reported the production of wheat additions to rye, in rye cytoplasm, by backcrossing tetraploid triticale in rye cytoplasm with diploid rye. Schlegel and Kynast (1988) transferred wheat chromatin to rye using an irradiation technique originally suggested by Sears (1956).…”

BAUM, M. 1991. Rye-wheat hybrids: the production of wheat chromosome additions to rye. Genome, 34: 840-844.To produce rye-wheat addition lines, 21-chromosome rye-wheat hybrids were produced by crossing tetraploid triticale with diploid rye. The subsequent selfing of the hybrids lead to monosomic and double monosomic wheat additions to rye. Screening of the progeny was carried out using the C-banding technique. The wheat additions can be fertile. Wheat chromosome 6B was the chromosome most frequently added to rye. Ribosomal spacer probe pTa250.4 was used to confirm the results obtained by C-banding for the 6B wheat additions to rye. Embryos of the 21-chromosome rye-wheat hybrids showed a good potential for propagating more plantlets after they had been transferred to artificial medium.Key words: rye-wheat addition lines.

Dans le but de produire des lignees d'addition seigle-ble, des hybrides seigle-ble a 21 chromosomes ont ete obtenus de croisements entre le triticale tetraploi'de et le seigle diploi'de. L'autofecondation subsequente chez les hybrides a conduit a des additions au seigle de monosomiques et de doubles monosomiques du ble. L'examen selectif des descendants a ete fait par la technique des bandes C. Les additions de ble peuvent Ztre fertiles. Le chromosome 6B du ble est celui qui a ete le plus frequemment ajoute au seigle. La sonde d'espacement ribosomique pTa250.4 a ete utilisee pour confirmer les resultats obtenus avec les bandes C pour les additions du 6B du ble au seigle. Les embryons des hybrides seigleble a 21 chromosomes ont montre un bon potentiel pour une propagation plus grande de plantules aprks avoir ete transferes dans un milieu artificiel.
