a field experiment was conducted at the seed and plant improvement institute research field station in karaj, iran, during the 2009-10 and 2010-11 growing seasons to estimate genetic progress and the variation in penological and agronomic characteristics in 13 irrigated facultative/winter bread wheat (triticum aestivum l.) cultivars released in iran between 1943 and 2011. trends of temporal var...

this research was carried out at the research farm, faculty of agriculture, bu-ali sina university in growing season of 2011-2012. the aim of research was to evaluate the effect of foliar application of nano-iron chelate and bacterization of mesorhizobium bacteria on root nodulation, growth, grain yield and yield components of chickpea under rainfed conditions. a randomized complete block desig...

Jatropha is a species with great potential for biodiesel production, and the knowledge on how the main agronomic traits are correlated will contribute to its improvement. Therefore, the objectives of this study were to estimate the genetic parameters of the traits: plant height at 12 and 40 months, canopy projection on the row at 12 and 40 months, canopy projection between the row at 12 and 40 ...

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...

to study the effects of nano-zinc oxide and seed inoculation with brady rhizobium and plant growth promoting rhizobacteria on yield and some agronomic traits of soybean, a factorial experiment based on randomized complete block design with three replications was conducted in 2013 at the research farm of the islamic azad university, ardabil branch. treatments were foliar application of nano-zinc...

a 7×7 complete diallel cross experiment was performed to study the genetic relationship of grain yield and some agronomic traits in rice. analysis of variance showed significant differences among genotypes for all traits. results of correlation analysis showed that rice grain yield was positively and significantly correlated with by (rp = 0.81, rg =0.55), hi (rp =0.35, rg =0.79), np (rp = 0.80,...
