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...

objective: wheat is the most important crop in iran. self sufficiency in wheat production is one of the economic and food safety policies in the country. in spite of the efforts which have been made in this area, the mean of wheat yield in iran is less than its world average. methods: in order to identifying of the high yielding wheat lines with optimal characteristics and to determine the trai...

To evaluate the performance of wheat plant height and spike-related traits under delayed sowing conditions, a screening trial was conducted for germplasm that exhibits resistance to late early maturity. The differences stability different dates were analyzed using 327 sources from wide range areas. results showed mean values generally decreased along with delay in dates. Broad-sense heritabilit...

BACKGROUND: Barley is one of the main important crops in the world, mainly used for animal feed and malt. OBJECTIVES: This study was conducted to evaluate the comparisons of seed yield and its components, phenological and physiological traits of different barley cultivars under Lorestan environmental condition. METHODS: Current rese...

Manure not only supplies many nutrients for crop production, but it is also a valuable source for increasing soil organic matter content and improving soil structure. To increase organic manure content as well as improve the wheat production adding plant residues and livestock to soil is necessary. The experiment was conducted in Shavoor Research Station to determine seed yield and soil physica...

this research was conducted to study the effects of different salinity levels and exposure times on grain yield and yield components in a green-house experiment at gorgan university of agricultural science and natural resources during 2007- 2008 growing season. a factorial sand culture experiment with three completely randomized replications was used. salinity levels were -0.002, -0.25, -0.50, ...
