Title

EFFECT OF HOMOLOGOUS GENOMES ON UNREDUCED GAMETE FORMATION IN WHEAT AND AEGILOPS CROSSES

Pages

  369-381

Abstract

 Production of UNREDUCED GAMETEs during meiosis is common among interspecific hybrids of plants. In the present study, two cultivars of bread WHEAT (2n=6x=42, AABBDD) were reciprocally crossed with Aegilops triuncialis (2n=4x=28; UtUtCtCt) and Ae. cylindrica (2n=4x=28; CcCcDcDc) to produce 20 interspecific hybrid combinations. The hypothesis was that UNREDUCED GAMETE formation in T. aestivum ´ Aegilops triuncialis (2n=ABDUtCt; which lack a common subgenome) is more than that of T. aestivum ´ Ae. cylindrica (2n=ABDDcCc) hybrids. This hypothesis was supported by the estimation of UNREDUCED GAMETEs in F1 hybrids. These results showed that lack of homologous genomes in T. aestivum ´ Ae. Triuncialis led to meiotic restitution in 3% of pollen mother cells (PMCs) resulting in UNREDUCED GAMETE formation and F2 seed production.
