Physical RFLP mapping on microisolated translocation chromosomes allowed for the first time to integrate precisely a number of translocation breakpoints into a genetic barley map. By this 37 breakpoints of chromosome 5 were exactly placed between the RFLP loci of linkage group 5 derived from the German Igri/Franka cross (Sorokin et al., this volume).
A number of 72 lines homozygous for single and multiple translocations are available as colchicine induced tetraploids. These lines, listed in Table 1, were grown in 1994 and evaluated for seed set. Small seed samples can be distributed upon request.
With respect to balanced tertiary trisomics there is no new information since the last report in BGN 23.
