Eight spring wheat cultivars were evaluated under three heat stress conditions (early, late and very late) in order to identify suitable cultivars to develop heattolerant genotypes resistant to future global warming. Results from the study indicate that stress did not negatively affect flag leaf area in ‘Prodip’ and ‘Sufi’, flag leaf dry matter partitioning in ‘Prodip’, ‘BARI Gom-26’ and ‘S...

ERECTA encodes a receptor-like kinase and is proposed as a candidate for determining transpiration efficiency of plants. Two genes homologous to ERECTA in Arabidopsis were identified on chromosomes 6 (TaER2) and 7 (TaER1) of bread wheat (Triticum aestivum L.), with copies of each gene on the A, B and D genomes of wheat. Similar expression patterns were observed for TaER1 and TaER2 with relative...

seed production, as well as other economical and ecological attributes, is an important character in grasses. knowledge on the genetic diversity of seed yield and yield components on iranian tall fescue accessions, as a high productive and adaptive grass is limited. this experiment was conducted to investigate the genetic diversity of seed yield and seed components, determine relationships betw...

breeding programs strategies depends on genetical mechanism of selection traits. in the present research, generation mean analysis with joint scaling test was performed to determine the gene action. f1, f2 and f3 generations, derived from roushan and kavir cross along with their parents were sown in a partial lattice design with two replications under stress condition at the research field of s...

in order to determine traits which affected grain yield in optimal irrigation and terminal drought deficit conditions, a field experiments with 16 spring bread wheat genotypes as randomized complete block design with three replications conducted in neishabour during 2009-10 cropping seasons. results of combined analysis of variance showed, significant differences between many of traits vegetati...

to investigate the effect of nitrogen rate and split form of application on dry matter remobilization among different rice cultivars, a field experiment was carried out in the rice research institute of iran (amol) – during 2005. a split–split experiment on the basis of a randomized complete block design with 3 replications involving 3 factors was employed in which fertilizer rates (100, 150 an...

knowledge about genetic diversity is an essential step towards conservation of genetic resources and developing further strategies for plant improvement. the objective of this research was to evaluate the agronomical and morphological traits and determine the level of variation within wild barley ecotypes especially for acclimation traits. in this study 188 ecotypes of wild barley (hordeumspont...
