Regression rate is one of the most important parameters in designing of hybrid rocket motors which is dependant into many factors like oxidant mass flux, grain length and chamber pressure. In this article, the effects of grain length and chamber pressure are considered besides of oxidant mass flux using HTPB-N2O lab-scale hybrid motor. Because of dependency of regression rate into three factors...

  Application of selection index for screening desired plants based on complex quantitative traits can be more effective than direct selection. This study was conducted using an F2 rice population consisting of 87 plants derived from a cross between two cultivars Gharib and IR28. The purpose was to establish suitable selection indices for increasing yield and its related traits in research farm...

relationship between grain yield and its component traits can improve the efficiency of breeding programs by determining appropriate selection criteria. an investigation was carried out on barnyard millet (echinochloa spp.) global germplasm collection to investigate the association among yield components and their direct and indirect effects on the grain yield of barnyard millet. the experiment...

In order to study the genetic conditions of some agronomic traits in wheat, a cross was made between Gaspard and Kharchia varieties. F2, F3 and F4 progenies with parents were evaluated under drought conditions. Three-parameter model [m d h] considered as the best fit for number of fertile tiller and flag leaf length using generations mean analysis method. For number of grain per spike and main ...

To identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between Norstar and Zagros cultivars were evaluated in a randomized complete block design with three replications. The measured characters consisted of peduncle weight, ...

In order to study the correlation of agronomic, morphologic and physiologic traits and their effects on grain yield of rice genotypes in two environments (favorable irrigation and water stress), 49 genotypes were evaluated using a completely randomized block design with 3 replications in two experimental conditions. All practices and conditions were the same for the two experiments with the exc...

Golestan province is one of the major regions of wheat production in the country. Azospirillum brasilense، an Azotobacter، acted as resolvent of phosphate and a microorganisms for fixing molecular nitrogen for cooperating with other root crops and grasses in enhancing their growth and development. To investigate the effects of rhizobacteria on yield and yield components of wheat a  factorial ex...

water use efficiency is positively correlated with grain yield, and being used for indirect selection of high wheat yield in drought prone environments. yet little is known about genetic control of water use efficiency. in this research, a half diallel mating design was generated from crosses between 8 bread wheat to study the genetic of water use efficiency. parents and f1 progenies were plant...

  Abstract In order to evaluate morpho-physiological traits of confectionery sunflower under different irrigation regimes, an experiment was carried out under field conditions in Agricultural Research Center of West-Azerbaijan province, Urmia, Iran in 2012. Fifty six confectionery sunflower landraces were arranged in 7 × 8 rectangular lattice design with two replications in each one of well-wat...
