to identify qtls controlling grain yield and yield components, an f2 population consisting of 188 plants derived from the cross between two rice pure lines, binam and kadous, were grown in research field of faculty of agricultural sciences, university of guilan, rasht, iran, in 2008, and were recorded for 9 important traits related to grain yield. to construct linkage map, 85 marker of ssrs and...

safflower is a crop native to iran and could be improved in plant breeding programs by inter-specific crosses. this study was conducted to evaluate genotypes of safflower derived from interspecific hybridization for the relationships between some agronomic traits and yield components. the genotypes were planted according to a randomized complete block design with three replications at the resea...

in this study the effects of source limitation on grain yield of twelve barley cultivars (‘aras’,‘jonub’,‘reihan’,‘zarjou’,‘sararoud’,‘sahra’,‘fajr30’,‘karoun’,‘gorgan’,‘makouei ’and ‘nosrat(’ under post anthesis water deficiency were studied. source limitation treatments were included that control, removing of awn, leaves below flag leaf, flag leaf and spike photosynthesis. all source limitati...

The current investigation was undertaken with eighteen elite rice genotypes to study the genetic diversity, variability, heritability and advance for yield attributing traits. ANOVA revealed significant variability among traits studied. 1000 seed weight is having highest phenotypic coeffcient variation genotypic (24.882 & 24.835) followed by grain per plant (20.315 19.523 respectively). Her...

in order to investigate of different salinity stress and plant densities effects on quantitative and qualitative forage and grain yields of kochia a randomized complete block design in factorial arrangement with three replications was used. a field study was conducted in 2011 cropping season in agriculture experiment satiation, college of agriculture, islamic azad university, arak branch treatm...
