Evaluation of essential oil yield, morphological and phenological traits of seven populations of twoChamomilespecies )Matricaria aurea and M. recutita), were carried out using Randomized Completely Blocks Design (RCBD) in three replications in Alborz research station in Karaj, Iran during 2011-2012. Data were collected for 12 morphological and phenological traits. Analysis of variance showed si...

Natural populations exhibit substantial variation in quantitative traits. A quantitative trait is typically defined by its mean and variance, and to date most genetic mapping studies focus on loci altering trait means but not (co)variances. For single traits, the control of trait variance across genetic backgrounds is referred to as genetic canalization. With multiple traits, the genetic covari...

the time of duration of plant developmental stages could have an effect on crop yield and adaptation in a specific environment. the aim of this study was to evaluate the phenological behavior in a wide range of wheat cultivars and their relation with adaptation and potential of crop production in a specific climate (semi-arid and cold). by using a simple lattice design with three replications i...

Alpine ecosystems are seriously threatened by climate change. One of the key mechanisms by which plants can adapt to changing environmental conditions is through evolutionary change. However, we still know little about the evolutionary potential in wild populations of long-lived alpine plants. Here, we investigated heritabilities of phenological traits, leaf size, and performance traits in natu...

Studies dedicated to understanding the behavior of pathogens in relation to their hosts are the starting point for any breeding program aimed to develop resistant cultivars. The objective of this study was to analyze the resistance to Septoria tritici Rob in 77 F11 progenies of wheat derived from the three-way cross Tadinia × (Yecora rojo × UC554) in the phenological stages of seedling, tilleri...

Identifying genotypes with a greater ability to absorb nitrogen (N) may be important reducing N loss in the environment and improving sustainability of agricultural systems. This study extends knowledge variability among wheat terms morphological or physiological root traits, uptake under conditions low soil availability, amount rapidity use supplied fertilizer. Nine durum were chosen for their...

The experiment was conducted using Randomized Complete Block Design with Row Column arrangement and three replications. Grain yield, phenological and other traits were recorded. The Residual Maximum Likelihood (REML) combined analysis of variance across locations showed very highly significant (P
