Fig. 2. Idiogram of rye chromosome 6R of triticale T-701 showing the locations of isozyme loci -Amy-R1, Got-R2, and PgdR2 and a nematode resistance gene CreR (lower) with respect to C-bands and band nomenclature (upper) Vertical arrowheads denote approximate sites of breakpoints on the long arm resulting in four different deletion mutants of chromosome 6R. Arm lengths and positions of C-bands were determined from measurements given in Table 1.
