The chromosomal location of the dwarfing gene present in the spring barley hordeum vulgare cultivar golden promise






Heredity 53(1): 177-184

The chromosomal location of the dwarfing gene present in the spring barley hordeum vulgare cultivar golden promise

Data from F2 and doubled monoploid populations segregating for major gene markers indicated that the dwarfing gene present in the spring barley varieties Golden Promise and Midas was located on chromosome 7. This was confirmed by the use of a suitable translocation stock, which showed that the gene was located on the short arm of chromosome 7. Single seed descent lines showed that an extra round of recombination was sufficient to break the linkage between the dwarfing gene and the rachilla hair locus. The implications of the use of dwarfing genes in breeding programs and the strategy for their deployment is discussed.
