Appropriate selection of donor parent for breeding purposes needs sufficient knowledge about genetic diversity and germplasm classification. In order to investigation and classification of genetic diversity in 35 wheat (Triticum aestivum L.) genotypes, an experiment was conducted in University of Shahed based on randomized complete block design with 2 replications in 2009. In persent study 15 m...

Introduction: salinity is known as the most important inhibitor of seed germination of most plants and limits the establishment of plants in arid and semi-arid regions such as Iran. The first effects of salinity on plant growth are associated with reduced seed germination and lack of uniformity in plant emergence. Currently, identification and utilization of tolerant cultivars are one of the mo...

Lisianthus is a slow-growing flowering plant whose seed germination and growth is a challenge in the tropics. Due to the marketability of this type of cut flower, this study was performed in two experiments to investigate the effect of seaweed extract (SWE) and LED on the growth of seedlings of two cultivars of lisianthus (namely Ariana and Mariachi) and its effect on flowering as a factorial e...

In order to determine suitable drought tolerance indices and to identify drought tolerant wheat genotypes, an experiment was conducted at the experimental field of Ardabil Agricultural Research Station in 2010-11 cropping season. Thirty wheat genotypes were evaluated in a randomized complete block design with three replications under stress as well as non-stress conditions. Drought tolerance in...

27 different populations of Triticum boeoticum were gathered from west and North West of Iran for their grouping using morphological traits. All populations were assessed in farm based on completely random design with three replications in 1393. The measured traits include stem length with spike, spike length with and without awn, awn length, flag leaf length, the woolly leaves, peduncle length...

Study of heritability and gene action to improve agronomic and physiological traits, especially under drought stress conditions, are very important. The objectives of this study were to investigate heritability for important agronomic traits and some physiological characters in a cross between two spring wheat cultivars. The experiment was carried out using different generations (BC1, BC2, F3, ...
