Notes:
General knowledge of the closed flowering trait, or cleistogamy, of barley is still limited. The relationship between cleistogamy and spike morphology characters was studied and linkage of cleistogamy genes with a highly significant quantitative trait locus (QTL) for rachis internode length on the long arm of chromosome 2H was detected. The mapping populations consisted of 129 doubled haploid lines of ‘Mikamo Golden’ × ‘Harrington’ and 150 F2 plants of ‘Misato Golden’ × ‘Satsuki Nijo’. The phenotypic variance explained by this QTL accounted for 77.5% and 82.6% of the variance in rachis internode lengt, respectively, in these two populations. The peaks of the QTL coincided with the positions of the cleistogamy gene loci.
