Fig. 7.

Discrimination of chromosomes originating from T. gesneriana (G) and T. fosteriana (F) in the genomes of ‘Kikomachi’ (2n = 2x = 24). (A) Genomic in situ hybridization to somatic metaphase chromosome complement showing 18 chromosomes of G (green fluorescence) and 6 F chromosomes (red fluorescence). Recombinant chromosome is defined as F/G indicating a T. fosteriana centromere with T. gesneriana chromosome segment. (B) A diagrammatic representation of chromosomes in ‘Kikomachi’ (2n = 2x = 24). In this figure, the black color represents the T. fosteriana genome, while white represents T. gesneriana one.
