The response of bread wheat genotypes to weed interference was evaluated under dryland conditions. An experiment was conducted with 26 genotypes of bread wheat and two known cultivars, Sardari and Azar2, as checks in a strip plot (Split block) arrangement based on Randomized Complete Block Design (RCBD) with four replications in 2002-03 at Dryland Agricultural Research Institute, Srarood, Ker...
an experiment was conducted to determine the effect of five plants densities (100,200,300,400 and 500 grain m-2) on yield and its components in three rain fed barley cultivars (ezeh, mahor and dopar). a factorial experiment based on randomized complete block design with three replications was conducted in agricultural research center of khorramabad city in the east of iran (in 2006-2007). in th...
An experiment was conducted to evaluate the effects of different levels of nitrogen and irrigation on yield and yield components of safflower. Three nitrogen rates (0, 50 and 100 kg ha-1) under three irrigation levels (100% as control 80% as mild limited irrigation, and 60% of crop water requirement as severe limited irrigation) were investigated using a factorial laid out in a randomized comp...
in order to study genetic diversity in 178 accessions of lentil (lens culinaris medik) originated from warm climate regions of iran, this experiment was conducted in 2009 at research farm of the national plant gene bank of iran in karaj. experimental design was an augmented experiment with six blocks and each block containes 30 accessions. accessions were compared with promising lines including...
An experiment was conducted to investigate the heterosis in 12 F1 hybrids of durum wheat using agronomic and morphological traits. Parents were selected according to the estimated genetic distances based on the results of a two-year field experiment, which were then crossed to produce F1 hybrids. Twenty-three genotypes (including 11 parents and 12 hybrids) were evaluated using a randomized co...
In grain amaranthus (Amaranthus hypochondriacus L.) ten genotypes were evaluated for twelve characters under four plant density levels viz. very high (D ), high (D ), normal (D ) and low plant density (D ) 1 2 3 4 levels to study the influence of different plant density levels on growth and grain yield of grain amaranthus. The study was conducted at College Orchard, Department of Horticulture, ...
Extended abstract Introduction and Objective: In order to increase the motivation of farmers to cultivate open pollinated oilseed rape cultivars, new cultivars with appropriate yields should be introduced. Also, due to the effects of climate change, increase in temperature, early arrival of heat and intensification of drought stress at the end of the season in the warm and dry regions, it is a...
salinity tolerance is a genetically and physiologically complex trait, controlled by quantitative trait loci (qtls). in order to map the qtls associated with agronomic and physiological traits, 149 doubled haploid lines derived from a cross between clipper (salt susceptible) and sahara 3771 (salt tolerant) barley genotypes were evaluated under natural saline-stress and non-stress conditions usi...
Extended Abstract Introduction and Objective: Flax (Linum usitatissimum L.) from the Linum genus and Linaceae family is one of the oldest oil products in the world. A natural population with sufficient genetic diversity is necessary to select the desired phenotypic traits, so the study of genetic diversity and the correct selection of essential tools is the main breed of plant. Agriculture fac...
this experiment was conducted using a randomized complete block design with three replications with 10 barley cultivars in dryland research station of northern khorasan (shirvan) in 2004-2005 growing season. results indicated that there was significant differences among the lines in terms of the stand percentage, days to emergence, days to heading, days to maturity, plant height, number of ...
