Twenty-five accessions of Triticum durum originating from different geographical areas of Iran and 10 durum cultivars from European countries were evaluated for high molecular weight glutenin subunit (HMW-GS) composition using SDS-PAGE. The data indicated the prevalence of the null allele (52%) and 2* subunit (48%) at the Glu-A1 and four alleles, namely 14+15 (32%), 13+16 (28%) and 7+20 (24%) represented about 80% of the alleles at Glu-B1 locus in the Iranian durum compared to European durum. This information can be a valuable reference for designing breeding program for the improvement of breed and pasta making quality of bread and durum wheat, respectively in Iran.
In this study different varieties of Bromus danthoniae in Iran are considered. Qualitative and quantitative morphological characters were evaluated for 32 accessions. Epidermal features were also studied for these accessions. The most variable morphological characters in the species delimitation were also determined. The varieties show significant variations in features as Awn status, Spike and spikelet length, Nerve number of Upper Glume, Lemma, Palea and Caryopsis length. Diagnostic features based on studied characters are identified and the varieties relationships are discussed.
In this study 39 macro-morphological features of 8 populations of Z. clinopodioides Lam. were studied to find their diagnostic features for distinguishing their different subspecies in Iran. Micro-morphological characters of epidermis and pollen grains were considered. In order to determine the most variable morphological characters among the species studied, factor analysis based on principal components analysis was performed using SPSS ver. 9. Palynological studies show the general form of tribe Mentheae. According to the present results, the pollen morphology in Ziziphora clinopodioides may be helpful in elucidating the infra specific relationships. Leaf micro-characters of epidermis were shown to be of great importance in the taxonomy of the Z. clinopodioides subspecies. Using complement macro-characters for taxonomic purposes is highly recommended in Ziziphora L.
