Karyotype Analysis of Multiple Translocation Stocks of Barley

Karyotype analysis of multiple translocation stocks of barley in which the translocated chromosomes could be distinguished from each other and from the remaining pairs revealed that chromosome 1 is not the longest chromosome in the normal karyotype. Estimates of the lengths of chromosomes 2 and 3 and the position of the breakpoints in T2-5a and T3-7d were also obtained. The data indicate that the breakpoint of T3-7d is in the short arm of chromosome 3 and not in the long arm as previously reported.
