FRONT COVER DIAGRAM

With the discovery by Kramer, Veyl and Hanson (1954) of the association of linkage groups III and VII as one chromosome, a seventh linkage group was designated. This linkage group became designated as chromosome 6 as a result of linkage associations between translocation stocks and an early maturing mutant ec by Ramage and Suneson (1958).

The first map of chromosome 6(A) was published in Barley Genetics I (1963) showing locations of translocations and four loci. Robertson also published a map of chromosome 6(B) in Barley Genetics I (1963) with associations of 9 loci.
The present map of chromosome 6(C) is from this volume of Barley Genetics Newsletter (Tsuchiya, 1979).
