In order to study the effects of supplementary irrigation and biofertilizers on grain yield, dry matter remobilization and some physiological traits of barley (Hordeum vulgare L.) under rainfed condition, a factorial experiment was conducted based on randomized complete block design with three replications at in 2017. Factors included irrigation at three levels (no irrigation as rainfed (I1), s...

Development of cultivars better adapted to drought stress in the arid and semi arid climatic conditions is considered as a major breeding objective. Grain quality is a trait with physico-chemical complexity depending primarily on genotype, is strongly affected by environmental factors and their interactions. Effect of terminal drought stress on quality traits of 18 triticale lines, comprising o...

Two durum wheat trials were carried out in Mediterranean conditions during 2010/2011 and 2011/2012 growing seasons at Plant Breeding Station-Elvas (Portugal). The experiments were conducted under rainfed conditions however, in 2012, due to extreme drought it was necessary to use artificial irrigation between booting and mid grain filling stage. Thirty durum wheat genotypes were studied and six ...

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,...

Principal component analysis is a valid method used for data compression and information extraction in a given set of experiments. It is a well-known classical data analysis technique. There are a number of algorithms for solving the problems, some scaling better than others. Wheat ranks as the staple food of most of the nations as well as an agent of poverty reduction, food security and world ...

cultivated area, yield and production trend of wheat (triticum aestivum l.), barley (hordeum vulgare l.), potato (solanum tuberosum l.), alfalfa (medicago sativa l.) and chickpea (cicer arietinum l.) as the main crops of kurdistan province were studied during 1983-2006 using time series analysis and the situation of future were predicted for 2006-2021 period. the results showed that the cultiva...

Extended Abstract Introduction and Objective: Wild relatives of wheat are one of the most important genetic resources for use in wheat breeding programs. Therefore, identifying wheat wild relatives and Awareness of the diversity in them, also protecting these species is undeniably effective in expanding the richness of the gene pool and the genetic base of new cultivars and can be a good tool ...
