Tillering and secondary stems in graminea plants are permanent characters, whereas there were being food matters and proper temperature for regeneration. Ratooning or regeneration phase is explained to remain of plant for growing in next season. Recombinant inbred lines (RILs) consisting of 80 lines, derived from a cross between Hashemi and Nemat were used to analyze the genetic basis ratooning...

  In this study, factor analysis was conducted to determine the factors which contributed to the variation of quantitative traits and path analysis was performed to find the direct and indirect effects of yield components on grain yield in bread wheat. A doubled haploid population of 157 lines of wheat (Triticum aestivum L.) was evaluated for agronomic and morphological traits, using a randomiz...

Salinity is one of a major abiotic stress, specifically on arid and semi-arid areas that has influenced on crop growth and reduced grain yield. The purpose of present study was identification of agronomic traits related to wheat grain yield variation under control and salinity conditions. In order to produce a population of 272 recombinant inbred lines (RILs), a cross between two bread wheat cu...

In order to investigate the relationship between morphological properties and choose suitable criteria for improving this research yield on ten new breeding lines and varieties of rice (control) modified rice cultivation area (Shiroodi cultivar) in the crop during 2010 in Tonekabon Rice Research Station in a randomized complete block design with four replications. The results showed that rice g...

This study was conducted to analyze the correlation among grain yield, yield components, duration of vegetative and grain filling periods in twelve oat (Avena sativa L.) cultivars at the Research Farm of the College of Agriculture, Isfahan University of Technology, from 2001 to 2003. A randomized complete block design with three replications was used. The correlation coefficients among the grai...

This study was conducted to investigate the genetic diversity of bread wheat, durum wheat and triticale using agronomic and physiological traits. Genetic diversity of 24 genotypes was evaluated in 2 locations (Research Farm of College of Agriculture, Isfahan University of Technology, located at Lavark, Najaf-Abad and Asheghabad farm), Isfahan, Iran, using a randomized complete block design with...

In this research, 50 quinoa genotypes were investigated using 40 pairs of microsatellite markers (SSR) to identify the superior genotypes in terms of grain yield, the components affecting it, and the features linked to the studied traits were also introduced using Association Analysis. The study of grain yield traits and the factors affecting it showed that the traits of day to physiological ma...
