In order to study the effects of different irrigation regimes and different levels of salinity on the growth parameters of Quinoa (Chenopodium quinoa Willd.), this experiment was performed in the research green house of Water Engineering Department, at f Gorgan University of Agricultural Sciences and Natural Resources, during 2016. The experimental design was a factorial with n a randomized com...

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...

Chrysanthemum is one of the most important ornamental plants. The genus chrysanthemum is a popular cut flower, medicinal and pot plant. Morphological traits such as cut rooting and leaf characteristics and genetic diversity among 50 genotypes of chrysanthemum morifolium were analyzed. Based on analysis of variance of data all traits in the studied genotypes showed significant differences at 1% ...

The first step of breeding programs and crops improvement are assess the genetic diversity and depends on germplasm availability and efficient utilization of their.This study was conducted to evaluate genetic variations among 70 sunflower recombinant inbred lines (RILs) obtained from the cross between PAC2  RHA266 based on the morphological traits by using a rectangular lattice design with two...

This study was accomplished with the aim of investigating the effects of tree decline and slope aspect on leaf morphological traits and determining the indicator morphological traits that indicate the leaf diversity of Persian oak trees in relation to habitat conditions and environmental stresses in Mellah Siah forests of Ilam. Two forest habitats were selected on the northern and southern slop...

In order to evaluate the effect of drought stress and determine of effective traits on grain yield and estimate of genetic parameters, 18 mutant rice lines were studied in normal and drought stress conditions. The experiments were carried out separately using randomized complete block design with three replications during cropping season 2014-2015 at Iranian Rice Research Centers in North of Ir...

Rice is one of the most important food crops, thus identification of definitive traits on the yield can be used in breeding programs. In order to determine the best suitable morphological markers for selection of superior genotypes, seeds of 15 rice genotypes including 5 varieties (namely: Binam, Dasht, Neda, Mashhad Domsiah and IR62871-175-1-10) and their 10 F1 hybrids of corresponding variate...

This study was conducted to evaluate the genetic diversity of sugar beet half sib inbred lines (48 lines and one control cultivar) under water stress (200mm of class A evaporation pan) in field conditions in a randomized complete block design with three replicates in Khorasan Razavi Agricultural and Natural Resources Research and Education Center in 2015. In this research, traits such as root y...
