Considering the importance of sunflower as one of the most important plants in the production of edible oils, present study was developed in order to determine the best nonlinear regression function which can quantify growth of diameter of sunflower head to time. At the present study in order to fit the best regression model explaining relationship between increasing of sunflower head diameter ...

In order to study the effects of different levels of nitrogen fertilizer and plant density on grain yield and its components in sunflower, an experiment was conducted using 'Record' cultivar at the Research Farm of College of Agriculture, Isfahan University of Technology in 1996. Four levels of nitrogen (0, 75, 150 and 225 kg/ha) and four plant densities (65000, 75000, 85000 and 95000 plants/ha...

This study was carried out in order to examine the contrastive relationship between seed yield and agro-morphological traits in confectionery sunflowers at molecular and phonotypical level via association mapping and sequential path model. In this study, 50 confectionery sunflower populations gathered from different regions of country were studied in completely randomized design with ten replic...

Extended Abstract Introduction and Objective: The selection of high-yielding genotypes is especially important in sunflower. Therefore, this study was conducted to identify interrelationships between different traits and the selection of the best sunflower hybrids. Material and Methods: In this study, 11 new hybrids along with four cultivars Golsa, Ghasem, Shams, and Farrokh were evaluated in...
