TABLE. The location of the rDNA loci and ITR sites in eight hyacinth species.
Cultivars45S rDNA loci5S rDNA lociITR sites
Five cultivars exhibited isomorphic location phenomena. On ‘Pink Pearl’ chromosome 6, ‘Gypsy Princess’ chromosome 6, ‘Yellow Stone’ chromosome 1 and ‘Red Pearl’ chromosome 5, 5S rDNA loci were located in the long arm, and ITR site were located in the short arm. On ‘Blue Pearl’ chromosome 4, 5S rDNA loci were located in the short arm, and ITR site were located in the long arm. ‘Pink Pearl’, ‘Gypsy Princess’, ‘Yellow Stone’ and ‘Red Pearl’ were closely related.
