in order to compare morphophysiological traits between new and old cultivars of barley (hordeum vulgare l.) a greenhouse experiment was conducted in greenhouse condition in faculty of agriculture, ferdowsi university of mashhad in spring and summer 2011.the type of experiment was a completely randomized design with eight treatments (nosrat , youssof , fagr30 , nick) and four old cultivars inclu...

to assess heritability, gene action and combining ability of rice varieties for characteristics related to grain appearance and cooking quality, the progenies derived from direct and reverse crosses of the 6×6 complete diallel together with their parents included hashemi, hassani, shahpasand, kadous, vandana and ir36 were grown in a randomized complete block design with three replications in th...

The five-parameter grain boundary distributions of grain boundary engineered nickel and copper specimens have been analyzed in detail. The relative areas of {111} planes in the entire population did not increase as a result of grain boundary engineering (GBE) and, in the R3-excluded population, decreased after GBE. This decrease occurred because the majority of the newly generated R3 grain boun...

Grain size and weight are important determinants of rice yield. The identification of beneficial genes from wild rice that have been lost or weakened in cultivated rice has become increasingly important for modern breeding strategies. In this study, we constructed a set of chromosome segment substitution lines (CSSLs) of wild rice, Oryza rufipogon with the indica cultivar 9311 genetic backgroun...

Before selecting genotypes for nutritional quality characters (protein, oil and micronutrients content) and anti-nutritional factor (phytic acid), it is important to know how much selection is likely to affect yield. Using a diverse range of genotypes, relationships between quality traits with yield and yield attributes in pearl millet were investigated. The number of productive tillers, panicl...

The dependence of grain orientation on stress-induced martensitic transformation in superelastic, polycrystalline Nickel-Titanium sheet was examined at the microstructural length scale. Full-field strains, indicative of transformation extent, were characterized in fields of view of nominally 100 μm x 100 μm using a custom combination of scanning electron microscopy with distortioncorrected digi...
