EVALUTION OF THE EFFECT OF THE NEW FRACTION PAIR 1Dx1.5+1Dy10 INHERITED FROM Glu-Dt LOCUS OF Ae. Tauschii (DtDt, 2n=14) ON SOME QUALITATIVE INDICES IN THE PROGENIES OF SYNTHETIC WHEAT VARIETIES (BBАuАuDtDt, 2n=42)

The effect of the new fraction pair 1.5+10, coded by Glu-D1 locus, on the qualitative indices protein, lysine and sedimentation value in synthetic hexaploid wheat varieties was investigated in comparison to common winter wheat standards. For this purpose, in two successive cropping seasons (2013 and 2014), grains from plants of the progenies of the synthetic haploid wheat genotypes 106, 107 and 32 were analyzed; preliminary SDS-PAGE analysis determined that they were carriers of the new allele ah inherited from the Glu-D t 1 locus of Ae. tauschii . Data were analyzed with the help of descriptive statistics, t-criterion, correlation and regression analyses, which were at the basis of the conclusions made. The obtained results allow the assumption that in the synthetic hexaploid wheat genotypes the new allele ah , coding for the expression of the new fraction pair 1.5+10 in D-genome, has positive effect on the qualitative indices protein, lysine and sedimentation in contrast to the standard common wheat cultivars, which do no carry this subunit.
