27 different populations of Triticum boeoticum were gathered from west and North West of Iran for their grouping using morphological traits. All populations were assessed in farm based on completely random design with three replications in 1393. The measured traits include stem length with spike, spike length with and without awn, awn length, flag leaf length, the woolly leaves, peduncle length...
Development of superior crop varieties is the prime objectives of all plant breeding programs. To determine genetic variability, heritability and genetic advance, 24 elite bread wheat lines were planted in randomized complete block design with three replications at the University of Agriculture, Peshawar under rainfed conditions. Data were recorded on days to heading, days to maturity, plant he...
Extended Abstract Introduction and Objective: In order to investigate the effect of foliar application of main elements and micronutrients on morpho-physiological and yield traits of rice plants with the aim of increasing yield and reducing the use of chemical fertilizers, experiments in the cropping years 2015-2016 and 2016-2017 in the research farms of Nowshahr city (Mazandaran) was implemen...
The aim of this study was to obtain the information for improvement in source ability via expansion of a flag leaf area in rice (Oryza sativa L.). We identified chromosome regions affecting a trait (CRATs) for leaf area and confirmed their effects with two sets of chromosome segment substitution lines developed from indica landraces Kasalath or Nona Bokra as a donor under japonica cultivar Kosh...
The appropriate timing of developmental transitions is critical for adapting many crops to their local climatic conditions. Therefore, understanding the genetic basis of different aspects of phenology could be useful in highlighting mechanisms underpinning adaptation, with implications in breeding for climate change. For bread wheat (Triticum aestivum), the transition from vegetative to reprodu...
Genetic diversity is prerequisite for any crop improvement program as it helps in the development of superior recombinants. Fifty Malaysian upland rice accessions were evaluated for 12 growth traits, yield and yield components. All of the traits were significant and highly significant among the accessions. The higher magnitudes of genotypic and phenotypic coefficients of variation were recorded...
We investigated the natural variations in the flag leaf morphology of rice. We conducted a principal component analysis based on nine flag leaf morphology traits using 103 accessions from the National Institute of Agrobiological Sciences Core Collection. The first component explained 39% of total variance, and the variable with highest loading was the width of the flag leaf (WFL). A genome-wide...
In this experiment the effect of inoculation with Azospirillum on the flag leaf and spike rachis anatomical features and also on grain yield and grain weight was investigated for the first time in bread and durum wheats during 2015-2016 growing season under semi-arid condition. The crop yield increased due to the inoculation with Azospirillum with a maximum yield increase of about 8.0 per cent ...
in order to investigate the effects of applying three and five continuous periods of municipal solid waste (msw) with and without npk chemical fertilizer on the amount of micronutrient uptake by different parts of wheat, a pot experiment was conducted in split plot based on randomized complete block design with four replications in 2009. the main plot was a six-fertilizers level including contr...
Determining the relationships between grain yield and some yield components of wheat is most important in permanent yield production. Using path coefficient analysis in order to determine key traits affecting majorly yield, and also to study direct and indirect effects of yield and yield components, this research was performed during 2006-2009 ys using 94 doubled-haploid (DH) lines, their...
