effect of terminal drought stress on seed yield and its components of some new winter rapeseed lines
drought causes significant reductions in crop productivity in many parts of the world, including iran. identifying genotypes tolerant to drought stress is therefore one of the foremost goals of crop breeding programs. this study investigated the effect of terminal drought stress on yield and yield components of new winter rapeseed lines, and identified new winter rapeseed lines tolerant to term...
The main objective of this research was to evaluate fifteen durum wheat (Triticum durum) genotypes selected from joint project of Iran/ICARDA for drought tolerance using several indices. The trials were conducted under moderate levels of drought stress for three cropping seasons (2004-2006) in four locations in the highlands western of Iran. The combined ANOVA for grain yield over years and loc...
The present study was conducted to investigate the genetic diversity and evaluate the drought tolerance indices on 16 genotypes of faba been based on split plot design with three replications in Agricultural Research Center of Borujerd. Irrigation regimes as the including normal and drought stress levels and genotypes were considered as the main and sub plot,respectively. Analysis of variance f...
in dry region, root systems play a major roll in controlling plant growth and yield due to their importance in absorbtion of water and nutrients. in order to evaluate the morphological characteristics of root chickpea and obtaining proper morphological makers for screening drought resistant genotypes, four experiments were conducted in different phenological stages of growth including, seedling...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
Drought is one of the most important factors limiting crop yields around the world. Drought stress in plants, the change (increase or decrease) in the production of plant proteins. This research was carried out using bread wheat genotypes. For evaluation of leaf protein pattern in wheat, 10 genotypes were assayed with 3 replications under irrigated (non-stress) and rain-fed (stress) conditions....
In order to evaluation of gain yield and yield components in spring barely genotypes under normal and drought stress in flowering stage and identifying drought tolerant genotypes, sixteen barely genotypes were investigated in two separately Randomized Complete Block Design with three replications in West Azerbaijan Agricultural and Natural Resources Research Center, Urmia, Iran in agronomic sea...
Breeding and production of drought tolerant cultivars for arid and semi-arid area is very important. The present experiment was carried out to evaluate the effects of drought stress on seed yield and yield components of oilseed rape as well as identification of high yielding and drought stress tolerant genotypes. Eighteen new winter oilseed rape lines and commercial cultivars were evaluated und...
in order to evaluate of physiological traits, related to drought tolerance, an experiment was carried out in controlled condition. the experiment was conducted to assess the effect of drought stress on photosynthesis, chlorophyll fluorescence and photosynthetic pigments in two tolerant genotypes (mcc392 & mcc877) and two susceptible genotypes (mcc68 & mcc448) were grown in drought stress (25% f...
to study genetic diversity and drought tolerance in sesame genotypes, an experiment in a randomized complete block design with three replications in 2010-2011 was conducted at the agricultural research field, university of birjand under stress and non-stress conditions. the aim of this study was the testing of yield, tolerance index and bi-plot analysis. materials included genotypes birjand, kh...
