Abstract
Chromosome 1R is readily distinguished from all other rye chromosomes and from all the chromosomes of hexaploid wheat in both Giemsa stained root-tip metaphase cells and in Feulgen stained antipodal cells with highly endopolyploid nuclei. Studies of these cells, stained using the appropriate methods, show that the two varieties 'Weique' and 'Neuzucht' both contain a single pair of alien substituted chromosomes and confirm their identity as chromosome 1R. It is also shown that the two varieties 'Aurora' and 'Kavkaz' both possess a single pair of wheat-rye translocation chromosomes which contain at least the major part of the short arm of chromosome 1R.Keywords
