objective: wheat is the most important crop in iran. self sufficiency in wheat production is one of the economic and food safety policies in the country. in spite of the efforts which have been made in this area, the mean of wheat yield in iran is less than its world average. methods: in order to identifying of the high yielding wheat lines with optimal characteristics and to determine the trai...
In order to study of variability, relationship among traits, direct and indirect effects of traits influencing grain yield, 18 lines and cultivars of bread wheat were evaluated in a randomized complete block design with four replications during 2009-2012 cropping seasons. Coefficients of genotypic and phenotypic variability showed that lines had high genetic variation for peduncle length, grain...
Crop sequence is an important management practice that may affect durum wheat (Triticum durum Desf.) production. Field research was conducted in 2007-2008 and 2008-2009 seasons in a rain-fed cold Mediterranean environment to examine the impact of the preceding crops alfalfa (Medicago sativa L.), maize (Zea mays L.), sunflower (Helianthus annuus L.), and bread wheat (Triticum aestivum L.) on yie...
A field experiment was conducted inside a temperature gradient tunnel (TGT) at the ICAR-Indian Agricultural Research Institute, New Delhi during rabi 2014-15 to quantify impacts of elevated on thermal requirement, growth and yield wheat crop. Wheat crop subjected five treatments, i.e. +0ºC (representing ambient condition), +0.9ºC, +2.5ºC, +2.8ºC +3.5ºC.Temperature elevation 3.5°C increased accu...
In order to study the morpho-physiological traits of cotton cultivars ‎under the Influence of humic acid in saline conditions, a factorial field experiment was conducted in a randomized complete block design with three replications in Kashan in the growing seasons of 2014. The first factors included three cotton cultivars: Varamin, line 43200 and khordad, and the second factor consisted six...
In order to assess the relationship of grain yield and some of the agronomic traits recombinant inbred lines (RIL) population of bread wheat derived from the Roshan × Sabalan were used to detect the informative traits on grain yield as the suitable criteria for indirect selection and path coefficient analysis. Two hundred and sixty seven recombinant inbred lines with three control cultivars (Ro...
Optimum rice population densities and the response of rice yield and yield components to population densities and planting pattern are important factors helping rice producers and researchers to achieve maximum productivity. For this reason, a randomized complete block design experiment was conducted during the summer of 1995 at Isfahan University of Technology Research Farm located at Lavark, ...
