in order to determine the best traits related to indirect increasing of grain yield, five wheat genotypes (zagros, tajan, durum cul., kohdasht and n-81-18 line) were evaluated by using randomized complete block design (rcbd) with 4 replications in research field of gorgan university of agricultural sciences and natural recourses. the studied traits included leaf area index (lai), crop growth ra...
water logging stress is one of the most important factors which affect wheat production particularly in western regions of golestan province. this experiment was carried out in order to evaluate of six genotypes (n-81-18, arta, moghan, n-80-19, urwyt-82-11 and urwyt-82-17) of bread wheat in water logging condition at 2006-2007 growing season in gorgan agricultural research station. the experime...
to evaluate of quantitative and qualitative yield of two basil (ocimum basilicum l.) medicinal plants as affected by planting pattern and plant density, an experiment carried out in factorial arrangement basis on randomized complete block design with three replications. two varieties (green and purple) of basil, two planting patterns (single and double row) and four plant densities (40, 60, 80 ...
to evaluate interaction of salinity stress and nitrogen use methods on yield and yield components, in experiment was conducted in split plot in randomized complete block with 3 replications. treatments included: salinity of irrigation water levels 1.5, 4.4 and 7.9 ds/m as main plots, and nitrogen treatments 1. using n fertilizer at 3 stage in soil, 2. using two third n fertilizer in soil at pla...
This study the effect of seed preparation (priming) with different concentrations of hydrogen peroxide on the anatomy of the flag leaf and spike two wheat genotypes( Cross Sabalan ( bread wheat) and Saji(durum wheat)) and its relationship with grain yield, under dry land farming system condition, Experimental design was factorial, arranged in randomized complete block. Results showed that the n...
An experiment was conducted to investigate the genetic diversity in the cultivars and F1 hybrids of durum wheat, using agronomic and morphological traits. Evaluation of consistency between choosing parents of crosses based on morphological and agronomic observations and genetic distance obtained from cluster analysis were objectives of this study. Fourty- two genotypes were evaluated using a ra...

Abstract In order to study the inheritance of grain yield and its components in bread wheat, two cultivars, Karchyya(drought and salinity tolerant) and Gaspard (sensitive to drought and salinity stress) were crossed.Parents together with F1, F2, F3, BC1and BC2 generations were evaluated using a randomized complete block design with three replications in 2008-2009 growing season.Grain weight per...
In order to study the relationships between grain yield and its components of Aegilops cylindrica, 48 accessions of this plant species was studied in an experimental augmented design based on randomized complete block designwith4 replications under normal and drought stress conditions in the Agricultural Research Station of Ilam University. The results of correlation analysis between the traits...
BACKGROUND: Barley is one of the main important crops in the world, mainly used for animal feed and malt. OBJECTIVES: This study was conducted to evaluate the comparisons of seed yield and its components, phenological and physiological traits of different barley cultivars under Lorestan environmental condition. METHODS: Current rese...
