V. Korzun et al., RFLP-BASED MAPPING OF 3 MUTANT LOCI IN RYE (SECALE-CEREALE L.) AND THEIR RELATION TO HOMOEOLOGOUS LOCI WITHIN THE GRAMINEAE, Theoretical and Applied Genetics, 95(3), 1997, pp. 468-473
Three mutant loci of rye determining absence of ligules (al), waxless
plant (wa1) and waxy endosperm (Wx) characters were mapped in a single
F-2 population, comprising 84 individual plants. The three loci could
be clearly tagged in relation to 7 (al on chromosome 2R), 4 (wa1 on c
hromosome 7R) or 6 (Wx on chromosome 4R) RFLP markers. The mapping dat
a are compared with existing data for homoeologous regions containing
equivalent mutants of wheat, barley, rice and maize. It is shown that
the loci analysed are highly conserved across the cereal species, incl
uding rye.
