The effects of major genes on quantitatively varying characters in barley 2. The denso and daylength response loci

The effects of the denso dwarfing gene and a locus determining daylength response on quantitative characters have been examined in random inbred lines. Since random inbred lines were produced from F sub(1) hybrids by doubled haploidy and single seed descent it was possible to quantify the contributi...

Description
Summary:The effects of the denso dwarfing gene and a locus determining daylength response on quantitative characters have been examined in random inbred lines. Since random inbred lines were produced from F sub(1) hybrids by doubled haploidy and single seed descent it was possible to quantify the contribution of each individual locus to the additive genetic variation (D) for any given character. It was observed that the contribution of these loci to estimates of D decreased following rounds of recombination which therefore demonstrated that in these cases the association between major genes and quantitative characters was due to linkage disequilibria.
