in order to evaluate the waterlogging stress effects on yield and yield components of rapeseed, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental stage (seedling, stem elongation, flowering and g...

  In this study, factor analysis was conducted to determine the factors which contributed to the variation of quantitative traits and path analysis was performed to find the direct and indirect effects of yield components on grain yield in bread wheat. A doubled haploid population of 157 lines of wheat (Triticum aestivum L.) was evaluated for agronomic and morphological traits, using a randomiz...

Half diallel crosses of nine Iranian wheat cultivars were used to estimate the general and specific combining ability effects and other genetic parameters related to yield and its components. Parents with F2 generations were evaluated at Research Farm, College of Agriculture, University of Shahrekord, in a randomized complete block design with 3 replications. Partitioning of genotypes mean squa...

scarce water resources is a worldwide problem, still for iran, a country predominated by an arid and semi-arid climate, water limitation is more severe than for many other areas of the world. a field experiment was conducted to investigate the impact of irrigation regimes on growth, grain yield and irrigation water use efficiency in maize (zea maize l.) in 2006 at the research farm, college of ...

Extended Abstract Introduction and Objective: Drought stress is one of the most important factors in reducing yield and barley production in rainfed arid regions, and counteracting or reducing the effect of stresses as a useful solution to increase barley yield. Therefore, improvement of stress-tolerant and suitable barley cultivars for arid and semi-arid regions is essential. Material and Me...

20 hulless barley lines were assessed by grain yield and other agronomic traits in 2006 and 2007 in the research station of the university of tabriz, iran. the experiments in each year were carried out as randomized complete block design with four replications. the genotypes were significantly different for most of the studied traits. this indicated the existence of large genetic variation in t...

The present study was a part of a long time screening experiment that includeda high number of wheat landraces (Triticum aestivum L.) cultivated in Greece, andfocused on the agronomic point of view and the drought adaptation for some ofthese landraces. One of the most acceptable ways for the assessment of droughtresistance is the examination of yield and yield components in different waterregim...
