fusarium head blight (fhb) is an important disease in wheat worldwide that reduces grain yield, quality as well as contaminates grains to the mycotoxins. thirty spring wheat genotypes including 28 bread wheat and two durum wheat genotypes were evaluated for fhb under a randomized complete block design with three replications. grain yield and its components were evaluated by using two environmen...
With the aim of comparing the grain yield and yield components of 16 oilseed rape (Brassica napus L.) mutant lines with cultivars Talayeh, Zarfam, Express and Okapi as check cultivar an experiment was conducted based on randomized complete block design with three replications during 2015-2016 cropping season in experimental field of Seed and Plant Improvement Institute (SPII) in Karaj. Analysi...
in order to investigate the yield stability of eight promising rice genotypes, these lines along with shiroudi and fajr cultivars as control were sown in three regions of mazandaran province (amol, sari and tonekabon) as randomized complete block arrangements with three replications in 2012 and 2013. analysis of variance for grain yield indicated significant differences among the genotypes in a...
One component of integrated weed management is use of cultivars with high competitive ability against weeds. Balance between competitiveness and productivity of rice under condition of presence or absence of weeds, is complicated the breeding of rice cultivars to increase competitiveness against weeds. Path coefficient analysis has been widely used in crop breeding to determine the nature of re...
The effects of cultivar mixture cropping on yield, biomass, and water use efficiency (WUE) in winter wheat (Triticum aestivum L.) were investigated under non-irrigation (W0, no irrigation during growth stage), one time irrigation (W1, irrigation applied at stem elongation) and two times irrigation (W2, irrigation applied at stem elongation and anthesis) conditions. Nearly 90% of cultivar mixtur...
Chlormequat chloride (CCC) as one of the most important growth retardants has been used for manipulation of growth and yield of cereal crops; however, the effect of CCC has not yet been well understood under drought stress conditions. Therefore, one greenhouse and a field experiment were conducted to examine the effects of CCC on yield and yield components of wheat in drought conditions at Coll...
In order to investigate the effect of planting date on yield and yield components of grain sorghum cultivars, a factorial experiment was conducted at Research Farm of Yasouj University, in 2010, based on randomized complete blocks design and three replications. The studied factors included nine sorghum cultivars (SOR 1003, SOR 834, SOR 808, SOR 1008, SOR 1011, SOR 1009, SOR 1006, SOR 857 and SO...
Mutagenesis has been one of the important sources of genetic diversity and Plant mutants can be important bio-resources for crop breeding and functional genomics studies. Breeding conventional methods for generating of genetic variability are of low efficiency. We showed that treatment of seeds of rice(Hashemi cultivar) with 0.8% EMS for 8 h caused visible phenotypic variations on M2 rice mutan...
abstract to evaluate the effects of the irrigation termination in different growth stages on yield and its components of autumn’s canola cultivars in isfahan region. an experiment was conducted in 2005-2006 in kabotar abad research station. a split plot layout within a randomized complete block design with tree replication was used. main plots were seven level of the irrigation cut-off time (d1...
The aim of present study was to determine the relationship between grain yield and important agricultural characteristics for six lines of rice and Shiroodi cultivar as control in rice research station (Tonekabon) in west of Mazandaran Province in 2015. The experiment was conducted in a randomized complete block design with three replicates. Analysis of variance showed that there was a sig...
