CYTOGENETICS OF RECIPROCAL HYBRIDS BETWEEN TRITICUM ARARATICUM JAKUBZ. AND TRITICUM MONOCOCCUM L.

Published on

Reciprocal hybrids between T. araraticum and T. monococcllm were produced.
Morphologically, Fl hybrids were intermediate between the parent species and were
completely pollen sterile. At the first meiotic division, T. araraticum - T. monocoCCllm
hybrids showed a mean chromosome pairing of 4.95 I + 4.45 II + 1.95 III + 0.35
IV per cell, whereas mean chromosome associations for T. monococcllm - T. araraticllln
hybrids were 5.08 I + 5.8 II + 1.08 III + 0.42 IV per cell. T. monococcllm cytoplasm
was relatively more conducive for bivalent formation than that of T. araraticllm.
 

Keywords: T. araraticum, T. monococcum, allotriploid, amphiploid.
