GLI-B3 GLU-B2 ENCODED PROLAMINS DO NOT AFFECT SELECTED QUALITY PROPERTIES IN THE DURUM-WHEAT CROSS ABADIA X MEXICALI-75/

A study was made of the effects of the Gli-B3/Glu-B2 encoded prolamins on durum-wheat quality. Twenty-six F-3 lines from the durum wheat cro ss 'Abadia' x 'Mexicali 75' were analysed electrophoretically for prol amin composition and for the following quality parameters: SDS sedimen tation value. mixing properties, and percentage grain protein and perc entage vitreous kernels. The results showed that the presence or absen ce of the Gli-B3/Glu-B2 encoded prolamins did not result in any signif icant difference in the quality characteristics of the F-3 lines; howe ver. as expected, the LMW glutenins encoded at Glu-B3 showed large dif ferences and are therefore the major prolamins influencing durum wheat gluten quality.
