Six morphological traits of rice were evaluated in a 5 × 5 one-way diallel cross using a randomized complete block design corresponding with their F1 generations in 2007 at Iranian Rice Research Institute – Amol. Results from analysis of variance for traits of plant height, flag leaf angle, flag leaf length, flag leaf width, internode length and panicle length exhibited significant genetic diff...

In order to find out the importance of flag leaf in Hordeum vulgare L. cv. Hordea in some physiologic traits and photosynthetic and leaf senescence-related gene expression, a field experiment was carried out in Warwick University Research Farm, UK, in 2003. For more accuracy and statistical comparison of the calculated means, the experiment was carried out in 4 replicates. Random leaf samples w...

The seasonal change in leaf water potential and its components, stomatal resistance, specific leaf weight, photosynthesis rate, the activities of ribulose-1,5-bisphosphate carboxylase and nitrate reductase, and soluble proteins were measured in flag leaves (ninth from base in position), seventh and fifth leaves of wheat Triticum aestivum L. cv Kalyansona. Flag leaves had a lower water and solut...

During grain formation stage (90 to 110 days), the youngest flag leaf of rice (Oryza sativa L. cv. Jaya) remained metabolically most active (as indicated by cellular constituents and enzyme activities) and the third leaf the least active. At the grain development stage (110 to 120 days) the above pattern of age-related senescence of the flag leaf completely changed and it senesced at a faster r...

Half diallel crosses of nine Iranian wheat cultivars were used to estimate the general and specific combining ability effects and other genetic parameters related to yield and its components. Parents with F2 generations were evaluated at Research Farm, College of Agriculture, University of Shahrekord, in a randomized complete block design with 3 replications. Partitioning of genotypes mean squa...

This research was conducted to study relationships among yield and yield components in Orchard grass (Dactylis glomerata). For this purpose 25 half sib families derived from poly cross of 25 parental genotypes were evaluated under two moisture environments (normal and drought conditions) according to a randomized complete block design at the research farm of Isfahan University of Technology. Th...

Plant diurnal oscillation is a 24-hour period based variation. The correlation between diurnal genes and biological pathways was widely revealed by microarray analysis in different species. Rice (Oryza sativa) is the major food staple for about half of the world's population. The rice flag leaf is essential in providing photosynthates to the grain filling. However, there is still no comprehensi...

Study of heritability and gene action to improve agronomic and physiological traits, especially under drought stress conditions, are very important. The objectives of this study were to investigate heritability for important agronomic traits and some physiological characters in a cross between two spring wheat cultivars. The experiment was carried out using different generations (BC1, BC2, F3, ...

Appropriate selection of donor parent for breeding purposes needs sufficient knowledge about genetic diversity and germplasm classification. In order to investigation and classification of genetic diversity in 35 wheat (Triticum aestivum L.) genotypes, an experiment was conducted in University of Shahed based on randomized complete block design with 2 replications in 2009. In persent study 15 m...
