In order to evaluate the effect of terminal moisture stress on 20 barley promising lines (Hordeum vulgare) and for determination of their relative tolerance, an experiment was conducted based on randomized complete blocks design with three replications in growing season of 2010-2011. In this research some old indices such as, stress susceptibility index (SSI), tolerance index (TOL), mean produc...

In order to obtain pure lines of corn for direct sowing or their usage in crossing, it is necessary to provide pure genotypes. This experiment was carried out by the use of individual selection breeding method and the 198 S6 lines of maize were evaluated in 2007and 14 traits were measured on them. The results of descriptive statistics showed considerable variation among genotypes. The maximum a...

In three-line system, cytoplasmic male sterile (CMS) lines often were contaminated with cognate iso-nuclear maintainer lines during seeds multiplication processes. Therefore fingerprinting of breeding lines and identification of line-specific markers are prerequisite in genetic purity test. Six CMS lines including Neda-A, Nemat-A, Dasht-A, Amol 3-A, Champa-A, IR58025A and their iso-nuclear main...

In order to study tolerance of durum wheat (Triticum durum) lines to drought stress and also evaluating stress tolerance indices, an experiment based on randomized complete block design with four replications was conducted under two rain fed and supplementary irrigation conditions at Gachsaran station during 2011-2012 cropping season using 20 durum wheat lines. Results of combined analysis of v...

Salinity is an important limiting factor in the production of more plants, including rice. Due to the limited amount of cultivated area, identification of tolerant genotypes to environmental stresses and especially salinity is very important. The aim of this study was to investigate the genetic diversity among 114 recombinant lines derived from the intersection of local Tarom × Khazar cultivars...
