abstract in order to study the inheritance of grain yield and its components in bread wheat, two cultivars, karchyya(drought and salinity tolerant) and gaspard (sensitive to drought and salinity stress) were crossed.parents together with f1, f2, f3, bc1and bc2 generations were evaluated using a randomized complete block design with three replications in 2008-2009 growing season.grain weight per...

Current study was conducted to evaluate the effects of different seed priming and foliar spray micronutrients on bread wheat performance in semi-arid region Northwest Iran. Pre-sowing treatments were S1: no pre-sowing treatment (intact seeds), S2: hydro-priming, S3: bio-priming (seed inoculation with plant promoting rhizobacteria consortium: Azotobacter chroococcum + Azospirillum lipoferum), S4...

introduction barely (hordeum vulgare) is the fourth most important cereal after wheat, corn and rice. regarding the role of breeding to increase barley grain yield a large number of studies have been done in different countries. however, a few studies have been performed across golestan province, in iran. therefore, this study was conducted to know what barley traits have changed with grain yie...

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...

in order to study the sink-source physiological relationship, current photosynthesis, contribution and remobilization of assimilates to grain yield in wheat and triticale genotypes, a field experiment was conducted in iran, ahvaz area on 2003-4. treatments were two bread wheat (simareh and tawer), one durum wheat (showa) and two triticale (juvanillo92 and line 45) genotypes. grain weight change...

in order to determine the optimum planting date under deficit output area, this research was carried-out in 2010-11 and 2011-12 cropping seasons, in split-plot arrangement, using complete randomized block design with three replications in khuzestan agriculture and natural resource research center. main and sub plots were consisted of four planting dates (oct. 27 with 10 days interval) and four ...

to study response of bread wheat cv. sardari to row spacing and seeding rate and to determine the desirable seed density under cold rain-fed conditions a two-year study (2008 and 2009) was carried out in qamloo research station located in kurdistan. a strip plot design with three replications was used. four rows spacing including 15, 17.5, 20 and 25 cm as horizontal factor and four seeding rate...

Successful production and development of stable and adaptable genotypes only depend on the positive results achieved from the interaction between genotype and environment that consequently has a significant impact on breeding strategies. In this regard, we conducted an experiment to study genotypic differences of 16 lines durum wheat under both zinc sufficient and deficient stress during 2014-2...

Seed shattering is a key constraint to improvement of seed yield in perennial ryegrass and, as result, retention an essential trait for breeding this valuable crop. It unclear whether sources are available plant breeders. Field studies were conducted near Corvallis, OR 2 yr (2017–2018 and 2018–2019) identify genetic variation ascertain there was phenotypic traits that may contribute loss due sh...
