No new translocations or balanced tertiary trisomics were added to the World Collection last year. Hagberg, Hagberg and Sodkiewicz (BGN 13:32-35) assigned the breakpoints of 33 T6-7 translocations to positions in the two chromosomes. Limited amounts of seed of the translocations and balanced tertiary trisomics in the collection are available upon request.
