Mining elite alleles for grain size and weight is of importance for the improvement of cultivated rice and selection for market demand. In this study, association mapping for grain traits was performed on a selected sample of 628 rice cultivars using 262 SSRs. Grain traits were evaluated by grain length (GL), grain width (GW), grain thickness (GT), grain length to width ratio (GL/GW), and 1000-...
Improvement of bread quality in bread wheat (Triticum aestivum L.) depends on a thorough understanding of the genetic basis of important quality traits. Therefore, this study was conducted to investigate the genetic basis of wheat grain quality traits including kernel length, kernel width, 1000-kernel weight, grain protein content, Zeleni No, bread volume, moisture content, grain hardness, wate...
IExtended Abstract Introduction and Objective: The economic value of a genotype depends on its various traits and therefore the accurate knowledge of genetic behavior and identification of genomic locus involved in controlling these traits can help the breeder to improve genotypes. Material and Methods: In this study, the relationship between microsatellite markers with some important agrono...
In an ongoing research, 24 cultivated and wild cultivars of barley were evaluated for morphological characteristics of grain, pollen, and stomata. Traits of interest included length, width, and area. Results of variance analysis showed that all samples were differed in traits of stomata, grain, and pollen at probability levels of 1 and 5%, suggesting remarkable genetic variation among studied s...
In order to evaluate the productivity of 20 bread wheat promising lines using multivariate statistical methods, an experiment was conducted based on a randomize complete block design under terminal moisture stress, in 2011-2012. Factor analysis showed that the three first factors explained 66% of total variance. Plant height, peduncle length, 1000 kernel weight, harvest index, biological yield,...
Breeders often use generation means analysis to obtain information about inheritance, gene action, and to determine effective breeding methods to improve important agronomic traits, especially under drought stress conditions. To investigate the genetic parameters of agronomic and morphological traits in durum wheat, a field experiment was carried out using F1, F2, BC1 and BC2 generations obtain...
Crop wild relatives adaptively diversified for environmental stresses are valuable resources for crop breeding especially for climate change scenarios, supposedly worsening drought and heat conditions. In this study, genetic variation of 54 barley genotypes comprised of 47 H. vulgare spp. spontaneum genotypes collected from west of Iran along with Reyhan cultivar and six F1 hybrids resulted fro...
In order to determine the best intercropping combination of wheat (Triticum aestivum) and rapeseed (Brassica napus) based on total yield and landuse efficiency, an experiment was conducted during 2010-2011 growing season at Agricultural Research Farm of Faculty of Agriculture, Bu-Ali Sina University. This experiment used randomized complete blocks design and three replications. Treatments inclu...
objective: wheat is the most important crop in iran. self sufficiency in wheat production is one of the economic and food safety policies in the country. in spite of the efforts which have been made in this area, the mean of wheat yield in iran is less than its world average. methods: in order to identifying of the high yielding wheat lines with optimal characteristics and to determine the trai...
to investigate the changes in yield and yield components of dry land wheat (triticum aestivum l. cv agosta), under the influence of residue and nitrogen levels and different tillage practices, a field experiment was conducted during the 2006-2007 growing season, in the agricultural research station of the college of agriculture, shiraz university, iran. the experiment was designed as a split-sp...
