The morphology and cytology of T. turgidum AS2255 (AABB), A. tauschii AS60 (DD), the allotriploid AS2255 × AS60 (ABD) and the derived allohexaploid (AABBDD). a Fluorescent in situ hybridization (FISH) analysis of the 21 univalents presents at meiosis metaphase I in the meiocyte of an allotriploid plant. The probe 6C6-3 hybridizing to the centromeres fluoresced green. Bar: 10 μm. b Allotriploid pollen mother cells comprise a mixture of dyads (green arrowheads) and tetrads (red arrowheads). c Multi-colour genomic in situ hybridization of a root tip mitotic cell from an allohexaploid plant, showing 2n = 6x = 42. d Sequential multi-colour FISH of a root tip mitotic cell from an allohexaploid plant, showing that chromosomes of the A, B and D genome were all represented on basis of probes pSc119.2 (green), pAs1 (red), and pTa71 (yellow). e Morphology of 120 day old plants of AS2255, AS60 and their derived allotriploid (F1) and allohexaploid (S1). f Leaf width and length of the first four leaves of the plants. Whiskers indicate SD (allotriploid: n = 7, AS2255, AS60 and allohexaploid: n = 12)
