In order to investigation of chromosomal variation in various populations of Aegilops cylindrica from northwest of Iran, the karyotype of each populations was prepared using aceto-iron-hematoxilin staining and different chromosomal characteristics were measured. The results showed that the karyotype of these populations consisted of seven pairs of metacentric, three pairs of submetacentric and ...
Abstract A karyotypic study was performed on 12 Iranian local onion (Allium cepa L.) populations. A number of mitotic cells at metaphase stage for each population were prepared. Chromosomes of suitable mitotic cells were counted and various parameters, including long arm (L), short arm (S), total length of chromosome (TL), relative length of chromosome (RL), arm ratio (AR), r-value, total chro...
eight accessions of thyme medicinal plant, belonging to iranian endemic thymus daënensis, t. eriocalyx, t. migricus and an unknown thymus spp species, were tested for karyotypic analysis, using squash technique and 2% (w/v) aceto-orcein staining method. chromosomal parameters examined were: short arm (s), long arm (l), total length of chromosome (tl), arm ratio (ar), r-value, total chromosome v...
karyotypes of eleven iranian populations of trigonella foenum-graceum were investigated. somatic chromosome numbers of examined populations were determined as 2n = 14. chromosomal parameters were examined as follows: long arm length (tl), short arm, total chromosome length, arm ratio, r-value, form percentage of chromosome, total form percentage of karyotype. chromosomes were mostly metacentric...
The chromosomal spread and karyotype of Anjak (Schizocypris altidorsalis) from Hamoun Lake were determined using tissue squashing techniques with an injection of 1 mL/100 g body weight of 0.01% colchicines solution. Kidney and gill epithelia tissues were removed and used for karyotype analysis. The analysis of 145 chromosome spreads revealed the diploid chromosome number of this fish, 2n=48 and...

For QTL mapping of related salt tolerance QTLs and determining the contribution of each QTL to phenotypic variation, a population consisting of 96 F2:3 families derived from the cross Kharchia (parent tolerant) and Gaspard (susceptible parent) were evaluated during 2 years. Of the 92 microsatellite markers used to evaluate parents, 32 markers were polymorphic which were used for analysis. Three...
A karyotypic study was performed on seven species of Hordeum Genus including, H. vulgare, H. spontaneum, H. glaucum, H. distichon, H. geniculatum , H. bulbosum and H. violaceum. According to the cytological studies in the laboratory, chromosome numbers and ploidy levels of species were identified. Chromosome analysese including the length of each chromosome, long and short arms length and long ...
