Genetic diversity of 13 new cereals, primary tritipyrum lines, five triticale lines and nine Iranian bread wheat varieties was studied under the randomized completely blocks design in terms of agronomic and morphological traits. The highley significant difference was observed between genotypes for all traits except in the filamental leaf length, main leaf length and main leaf width. The highest...
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...
in order to study the effect of the usage of vermicompost and mycorrhiza fertilizer usage on yield quantity and quality of soybean cultivar l17 in water deficit stress condition, an experiment was conducted as plots in a split at randomized complete blocks with four replications in agricultural research center in 2013 in khoramabad. the experiment treatments including irrigation in three levels...
Correlation coefficient analysis conducted on 22 triticale x bread wheat derivatives along with six checks to select true- breeding derivative(s) for future hybridization programme with tolerance to drought and cold stress conditions as well as better quality traits revealed significant correlation of grain yield with spikelets per spike, biological yield, harvest index, leaf area index. Intere...
to determine the correlation between grain yield and its components in some grain corn hybrids and their cause and effect relationships in various fertilizer application methods, an experiment was carried out as split plot based on randomized complete block design with two fertilizer application methods (urea foliar application and soil application method), four grain corn hybrids (ns 640, kons...
In order to evaluate cold tolerance of twenty barley genotypes under field conditions, an experiment was carried out in a randomized complete block design at 3 sowing dates of October 5, November 5, and December 5 in Saatlu Agricultural Research Station, West Azarbaijan, Iran, during 2010-11 seasons. Also, another experiment was conducted on the same genotypes based on a completely randomized d...
In order to study the effect of drought stress and determination of effective traits on grain yield of wheat in normal and terminal drought stress conditions, 82 wheat genotypes were studied in two separate experiments using randomized complete block design with three replications during cropping season 2011-2012. Drought stress was applied in heading stage by limited irrigation. Set of 22...
The present study aimed at investigating the effect of different levels of nitrogen on yield and yield components of bread and durum wheat. To this end the experiment was conducted in 2010-2011 in south west of Iran as split plots based on randomized complete block design with three replications. Main plot included four levels of nitrogen 60, 120, 180, 240 kg.ha-1 and the sub plot included four...
Breeding new crop cultivars with efficient root systems carries great potential to enhance resource use efficiency, plant adaptation to unstable climates and improve yields. Current study was conducted to investigate the relationship between root characteristics with yield and yield components in 24 lines and cultivar of bread wheat using complete randomized block design with three replications...
in order to evaluate the effects of different levels of water and plant density on yield, yield components, morphological and physiological characteristics of a new corn hybrid (ksc 500), an experiment was carried out in 2006 in karaj area. the experimental design was split plot based on randomized complete blocks design with three replications. main plots were three irrigation levels: 75%, 100...
