Ki. Ereifej et Ra. Shibli, QUALITY EVALUATION OF LANDRACE AND DURUM-WHEAT CULTIVARS GROWN IN JORDAN, Journal of Food Science and Technology, 30(5), 1993, pp. 339-343
Ten 'Durum' wheat cultivars (including a 'Landrace', old and newly dev
eloped cultivars) have been evaluated for a number of quality paramete
rs. The 'Landrace Horani-27', had the highest protein content (14.4%),
but intermediate flour yield (43.7%). 'Lacesh', gave highest flour yi
eld (57.5%), particle size index (PSI) (19.7%), sodium dodecyl sulphat
e sedimentation (SDS-SED) (52 ml), but was intermediate in protein con
tent (9.7%). The old cultivars, 'Der Alla-2' and 'Der Alla-6' had no c
lear-cut patterns for the quality parameters studied. Proximate analys
is showed that these cultivars were higher than average for fibre and
ash contents. It was possible to cluster these cultivars into 3 groups
each for flour yield, protein content, SDS-SED, PSI% and thousand ker
nel weight. The variability in the composition of each cluster allows
for combining certain cultivars to complement each other for a better
balance of these quality traits.
