Genetic variation of 300 genotypes of durum wheat comprising CIMMYT/ICARDA and Iranian germplasm was evaluated in 1999-2000 at Researh Farm of College of Agriculture, Isfahan University of Technology located at Lavark, NaJaf-Abad. Days to heading, days to maturity, plant height, spike length, grain weight per spike, number of grain per spike, number of spikes per m2, 1000-grain weight, test wei...
Extended Abstract Introduction and Objective: Selection of desirable hybrids compared to other maize hybrids (Zea mays L.) is one of the methods used to achieve high grain yield in maize. Also, the most important morphological features affecting grain yield can be used in the selection and introduction of genotypes. Material and Methods: This study was conducted to investigate the relationshi...
in order to evaluate the relationship between grain yield and agronomic characteristics in bread wheat genotypes in different planting dates under rainfed conditions, a factorial experiment was conducted based on rcbd with four replications at gonbad-e qabus region, iran, during 2012-2014 growing seasons. number of spikes per unit area, grain filling rate, effective grain filling period, number...
genetic diversity is one of principle factors to succeed in breeding programs, so its determination is vital in the using of plant genetic resources. with the aim of evaluation of genetic diversity among safflower landraces, 20 lines (14 iranian and 6 foreign lines) were studied for phenotypic and genotypic variations using agro-morphological traits and rapd markers. field study was conducted i...
The present study was conducted to investigate the genetic diversity and evaluate the drought tolerance indices on 16 genotypes of faba been based on split plot design with three replications in Agricultural Research Center of Borujerd. Irrigation regimes as the including normal and drought stress levels and genotypes were considered as the main and sub plot,respectively. Analysis of variance f...
Chickpea (Cicer arietinum L.) is one of the most important crops worldwide that is a subject of many plant breeding programs in many countries. In addition, climates are changing all over the world and drought becomes one of the most serious problems versus yield of crops. In order to screen drought tolerant genotype in Chickpea, twenty genotypes were tested under rainfed and irrigated...
A great part of lands under corn cultivation are affected by different levels of salt stress. This study was conducted in order to determine the effect of different levels of salt stress on yield and some physiological characteristics of corn plants. Two experiments were carried out in greenhouse (a factorial based on randomized complete blocks design with 3 replications), and field (a split pl...
Twelve genotypes of bread wheat, with four levels nitrogen (0, 75, 150, 225 kg N ha-1). were grown in split block design three replication growing season (2021), correlation, phenotypic and genotypic coefficient variation, heritability genetic advance estimated for (days 75% flowering, plant height, grain filling, yield, number spike/plant, spike length, weight, flag leaf area, biomes, protein ...
The effects of salinity stress on grain quality traits of wheat were investigated using 180 lines of F5 generation in two environments (normal and salinity stress). A randomized complete block designs with three replications was used in each of the environments at the Research Farm of the Agricultural and Natural Resources Research Station of Isfahan in 2019-2020 cropping season. Grain yield, p...
The objective of this study was to investigate field trends in agronomic characters of soybean (Glycine max [L.] Merr.) performance trials. Field experiments were arranged as lattice designs, and for each plot within an experiment, an environmental covariate representing the spatial trend was calculated using neighbour analysis. Correlations between environmental covariates of different charact...
