Cadmium as an environmental pollutant heavy metals have effect on morphological and physiological activities in plants. Selenium, an essential element had beneficial effects on enhanced tolerance in plants against environmental stresses. In the investigation, from Cadmium chloride concentrations 0, 350, 700 µM supplied with added to soil and Sodium selenat 0, 1.5, 3 mg L-1 as a foliar applicati...

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, ...

abiotic stresses and lack of nutrients are one of the most important factors in reducing the crop yield.  vigorous and developed roots can facilitate uptake of water and nutrients more efficiently making it essential for enhancing the yield. association mapping is currently one of the approaches for detecting quantitative trait loci (qtls) influencing complex traits. this approach was used to d...

In order to study the relationship between grain yield and some of agronomic traits under drought stress condition, an experiment with 305 bread wheat inbred lines derived from a cross between Roshan × Falat and 25 drought tolerant and susceptible varieties along with 4 check varieties (Roshan, Falat, Mahdavi and Shahpasand) was conducted in augmented complete block design, at Research Field of...

Prediction of barley yield is an attempt to accurately forecast the outcome of a specific situation, using as input information extracted from a set of data features that potentially describe the situation. In this study, an attempt has been made to analyze and compare multiple linear regression (MLR), and artificial neural network (ANN) including multi-layer p erceptron (MLP) and r adial basis...

Wheat is one of the most widely distributed crops worldwide and is of primary importance as food for human nutrition. Increasing the productivity of the new wheat varieties according to the specific climate of the region is a permanent major task. The impact of environment and some agronomy practices (previous crop and mineral fertilization) on the productivity and the structural elements of yi...
