a Giemsa preparation in gray-scale of a somatic cell of Hybrid 5 (6x T. ambiguum x 2x T. occidentale) showing 2n = 4x = 32 chromosomes. Four NOR chromosomes are identified by dotted lines. b Giemsa preparation in grey scale of a somatic cell of an open-pollinated (OP) progeny plant of hybrid 5 (Hybrid 5OP-1). There are 2n = 48 chromosomes. Five NOR chromosomes are identified by arrows (main bodies) and arrowheads (satellites)
