RELATIONSHIP BETWEEN ALLELIC VARIATION OF GLU-1 AND GLI-1 GLU-3 PROLAMIN LOCI AND GLUTEN STRENGTH IN HEXAPLOID WHEAT/

Allelic variation of prolamin loci was examined in the F-2 from crosse s between the hexaploid wheat varieties: 'Cajeme 71', 'Yecora 70', 'Ab laca', 'Anza', 'Pane 247' and 'Axona'. Different allelic blocks for gl iadins and LMW glutenin subunits were determined in Gli-1, Gli-2 and G lu-3 loci. A percentage of recombination of 1.5 +/- 0.3 was determined between Gli-A1 and Glu-3 in the F-2 progeny of 'Yecora 70' x 'Axona'. A significant positive association was found between gluten strength, measured by SDS-sedimentation volume, and the prolamins coded by 'Anz a' Gli-D1/Glu-D3 loci and 'Yecora 70' Gli-A1/Glu-A3 loci. Interactions between non homeologous loci Glu-1 and Gli-1/Glu-3 were also found.
