in order to  study of environment × genotype interaction and selection of stable and high yielding and cold  tolerant chickpea lines, this study carried out  with 13 chickpea genotypes along with one local check (jam) in a rcb design with four replications during three cropping seasons (2009-2012) in agricultural research station of maragheh (dari). the genotypes were exposed to cold temperatur...

grass pea(lathyrus sativus l.) is a crop used for both animal and human consumption. recently, icarda has developed new grass pea lines with the objectives of improving its yield potential and adaptability. the objective of this study was to investigate grain and forage yields stability of several icarda released grass pea lines by using additive main effects and multiplicative interactions (am...

mapping the QTLs of agronomic and physiological traits, 149 double haploid (DH) lines from a cross between an Australian cultivar, Clipper (salt susceptible), and an Algerian landrace, Sahara3771 (salt tolerant), were evaluated under natural saline (Yazd Station, ECsoil=10-12.8 ds/m and ECwater= 9-10 ds/m) and normal (Karaj Station, ECsoil and ECwater ~2-2.5 ds/m) environments. There were remar...

background: this study aimed at determining the appropriate method for dewatering and drying biomass and selecting a suitable organic solvent for lipid extraction. methods: nannochloropsis oculata was cultured in gillard f/2 medium and after reaching the end of the stationary growth phase, algal biomass was separated from aqueous by centrifuge and dried through three methods: oven, air-dried an...

Characterization of genetic variability in a population is pertinent as genetic diversity within population and within species determines the extent of improvement achieved through crop improvement 8 methods. One hundred ninety six F recombinant inbred lines (RILs) of tef, developed by single-seed descent method from a cross between two tef varieties DZ-01-196 and DZ-01-2356, were evaluated to ...

The aim of this study was to efficiently use barley straw as a lignocellulosic feedstock for biobutanol production. Dilute sulfuric acid pretreatment was employed to solubilize hemicellulose in barley straw from cellulosic residues. The pretreated hydrolysate was cofermented with starch-based biomass in acetone–butanol–ethanol (ABE) fermentation. There were two co-fermentation processes: I) Bar...

this study was performed to investigate the photosynthetic partitioning pattern of materials to aerial parts of bread wheat in dryland conditions. it was as well to study its relationship with bread wheat resistance and grain yield in drought conditions. seven genotypes including two cultivars (azar2, sardari) and five lines were investigated in a field experiment through a randomized complete ...

More efficient resource use, especially nitrogen (N) in agricultural fields could considerably reduce the losses and spillover effects on environment. Cereal-legume mixtures can lead to more uptake of growth-limiting resources, increase stabilize yields, due variation functional traits that facilitate partitioning niche space. Here we identify crop with optimal N use two selected cereal-legume ...

Agrotain has shown in previous studies on silt loam soils to be much less prone to ammonia volatilization loss and to result in higher rice-grain yields compared to urea when the flood cannot be applied immediately after nitrogen (N) fertilizer application. However, no research has been conducted to determine if Agrotain is superior to urea as an N source for rice grown on clay soils, which vol...
