to identify the high yielding lines with optimal characteristics, 40 recombinant inbred lines derived from a cross between ‘norstar’ (winter wheat) and ‘zagros’ (spring wheat) cultivars were examined using a randomized complete block design with three replications in 2014 at the research station of faculty of agriculture, university of tabriz, iran. the measured characters consisted of peduncle...
effects of drought stress and chemical treatments was studied on growth and developmental traits of four barley cultivars using a split- split plot design (rcbd) in agricultural research farm, kerman university. main plots consisted of irrigation (control and drought stress after flowering), sub-plots consisted of four barley cultivars ( ʻnosratʼ, ʻafsalʼ, ʻyousofʼ and ʻuh12 lineʼ) and sub-sub ...
Improving the drought tolerance of barley varieties through the integrated efforts of plant biotechnology and conventional breeding is an important objective in barley breeding. One hundred and fifty eight doubled haploid lines of barley were mapped with 50 SSR and 93 AFLP markers. Agronomic traits such as early growth vigor, plant height, peduncle length, extrude of spike from flag leaf, spike...
In order to study the relationship between morphological and agronomic characteristics like grain yield in barley, and to obtain better knowledge of the effective attributes on barley, an experiment was conducted at the Agricultural Research Station of Ghachsaran in randomized complete block design with two replications on 18 barley lines. Results showed that some characteristics such as days t...
In order to evaluate and grouping wheat genotypes based on grain yield and important agronomic traits under drought stress, a field experiment was conducted with 43 wheat genotypes using a Randomized Complete Block design in three replication at Azad University, khorramabad, Iran in 2012-2013 cropping season. Evaluated traits were: day to maturity, day to pollination, grain filling rate, grain ...
Long awns are important for seed dispersal in wild rice (Oryza rufipogon), but are absent in cultivated rice (Oryza sativa). The genetic mechanism involved in loss-of-awn in cultivated rice remains unknown. We report here the molecular cloning of a major quantitative trait locus, An-1, which regulates long awn formation in O. rufipogon. An-1 encodes a basic helix-loop-helix protein, which regul...
in this study, we aimed to determine the effects of halo-priming on yield and yield components of four wheat cultivars in a saline soil. a field study was conducted in factorial based on randomized complete block design (rcbd). soil ph was 8/1 and electrical conductivity was 9 ds/m. wheat cultivars (falat, ghods, chamran and shoori4) were primed with cacl2 solutions (control, 0, 50 and 100 mm)....
Two crosses of bread wheat viz., K 1006 x LOK 1 and PBW 343 HUW 234 were investigated to explore the useful variability parameters, correlation along with inheritance study (skewness kurtosis) in segregating F2 F3 population for yield its component traits respectively. Narrow difference between phenotype genotype coefficient variation showed less influence environment on expression under invest...
effects of drought stress and chemical treatments was studied on growth and developmental traits of four barley cultivars using a split- split plot design (rcbd) in agricultural research farm, kerman university in 2013-14. main plots consisted of irrigation (control and drought stress after flowering), sub-plots consisted of four barley cultivars (ʻnosratʼ, ʻafsalʼ, ʻyousofʼ and ʻuh12 lineʼ) an...
The awn, an apical extension from the lemma of the spikelet, plays important roles in seed dispersal, burial, and photosynthesis. Barley typically has long awns, but short-awn variants exist. The short awn 2 (lks2) gene, which produces awns about 50% shorter than normal, is a natural variant that is restricted to Eastern Asia. Positional cloning revealed that Lks2 encodes a SHI-family transcrip...
