Environmental stresses can play an important role in the reduction of the plant growth stage,
especially drought during germination in arid and semi arid regions in Iran. In order to study of the response
of 37 of durum wheat landraces from Iran and Azerbaijan republic were evaluated in drought stress under
laboratory and greenhouse conditions at recovery germination was investigated, on base of the completely
randomized design with three replications. Analysis of variance has indicated that there were significant
differences among the genotypes in total germination percentages, recovery germination percentages in
greenhouse condition and recovery germination percentages in laboratory condition, which indicate that there
are great variations among genotypes in order to use in breeding programs. Recovery germination percentages
in laboratory condition showed positive and significant correlation with recovery germination percentages in
greenhouse. Cluster analysis divides the genotypes into three groups. The best genotypes were included in a
group which confirms the results of the compared means yield, these genotypes could be used as source of
germplasm for breeding of drought tolerance.
Key words: Cluster analysis, durum wheat, germination, recovery, water stress, ,
