Title: Mapping of the genes controlling high-molecular-weight glutelin subunits of rye on the long arm of chromosome 1R
Abstract: SUMMARY The gene(s) controlling the high-molecular-weight glutelin subunits in rye (designated as Glu-Rl ) was mapped with respect to the centromere using a 1RL-1DS wheat-rye translocation line and sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Analysis of 479 seeds from test-crosses between a 1R/1RL-1DS heterozygote and the cultivar India 115, revealed 14·6% aneuploid and 3·95% recombinant progeny. Excluding the aneuploids, this locus was calculated to be 4·65 ± 1·04 cM from the centromere on the long arm of chromosome 1R, which is comparable to the position of the homoeologous loci in wheat and barley.
