| description | Durum wheat is used predominantly for pasta and couscous but the use of durum
wheat for breads is also common in Mediterranean countries. High molecular weight (HMW-GS) and
Low molecular weight glutenin subunits (LMW-GS) play an important role in determining the bread
quality of durum wheat. In this study we used twenty one local and introduced durum wheat varieties
cultivated in Algeria, that were grown in the same environmental conditions. These cultivars were
evaluated for their variability in several traits related to technological qualities. The present study
showed the presence of significant differences within our genetic resources for several traits. Indeed,
by SDS-PAGE, a low diversity was shown among genotypes used at Glu-A1 locus, confirming the
dominance of (c) allele, however Glu-B1 present a high diversity with the superiority of (b) and (e)
alleles. Based on mixing time (MT) and bandwidth at peak dough resistance (BWPDR) values,
Mixograph test indicated a mean score of 6.5 suggesting a good bread making ability of Algerian
durum wheat. In fact, Ofanto, Mexicali75, Vitron, Chen’s and Saoura held the top of the rank scoring
a value of 8, followed by Hedba03, Simeto and Marzak (used as check) showing a score of 7.5. This is
due to the presence in their flours a high gluten strength according to the test of SDS sedimentation.
These results are very motivating to be used in local durum wheat improvement program. |
