EFFECT OF SOME COMMERCIAL BIO-AGENTS ON YIELD AND DAMPING-OFF DISEASE OF WHEAT LINES (Triticum aestivum vulgair L.)

2015 | Keywords Wheat lines, Damping-off, Bio-, wheat, Bio-agents, yield,
EFFECT OF SOME COMMERCIAL BIO-AGENTS ON YIELD AND DAMPING-OFF DISEASE OF WHEAT LINES (Triticum aestivum vulgair L.)
The current study was conducted to assess the possibility of using two bioagents (BAs), Trichoderma harzianum T39 (Trichodex) and Bacillus subtilis (MBI 600) tested at 1, 3 and 5% concentration to control damping-off disease and also their ability to promote yield of wheat lines under field conditions. Seed inoculation with two BAs protected wheat seedlings and highly promoted seed germination. ... Read more

Identification of ISSR and RAPD markers linked to yield traits in bread wheat under normal and drought conditions

2015 | Keywords DroughtGenetic diversitySingle,
Identification of ISSR and RAPD markers linked to yield traits in bread wheat under normal and drought conditions
Genetic variability and identification of some molecular markers were studied in twenty promising lines of wheat using agronomic traits, ISSR (inter simple sequences repeats) and RAPD (random amplified polymorphic DNA) markers. Significant variation was evidenced in all agronomic traits. The lines proved to be superior to the check cultivar Sahel1 in yield and its component traits. Lines L2, L7 and ... Read more

Association Mapping For Salinity Tolerance Related Traits in a Structured Barley Population.

2015 | Keywords Barley QTL Salinity,
Association Mapping For Salinity Tolerance Related Traits in a Structured Barley Population.
ASTRUCTURED barley population of 103 wild barley accessionand 19 spring barley cultivars was used to identify quantitativetrait loci (QTLs) for salt tolerance traits by means of an associationmapping approach using 660 DArT markers. In this investigationbarley accession and spring barley cultivars were employed in a twoyeargreenhouse project having a completely randomized designinvolving four irrigation water treatments having different salinitiesand twice ...

Stability Parameters for Comparing Bread Wheat Genotypes under Combined Heat and Drought Stress.

2014 | Keywords Stability parameters Wheat,
Stability Parameters for Comparing Bread Wheat Genotypes under Combined Heat and Drought Stress.
COMPARISON of ten local and twelve introduced wheat accessions was performed on twelve different induced environments (2 years × 2 sowing dates × 3 water stresses) to analyze genotype × environment interactions (G×E) and estimate stability indices of yield and its components. Mainly the total variations of studied traits were due to the main effects of environmental factors and their ... Read more

Generation mean analysis in wheat (Triticum aestivum L.) under drought stress conditions.

2014 | Keywords
Generation mean analysis in wheat (Triticum aestivum L.) under drought stress conditions.
The six populations (parents, F1, backcrosses and F2) of the two wheat crosses, Gemmeiza 9 · IL1 (C1) and Sids 1 · IL2 (C2) were grown under normal irrigation (N) and drought stress (D) at the farm of Faculty of Agriculture, Sohag University, Egypt to study the genetic background of drought stress tolerance. Genetic variation was found for No. of ... Read more

Association mapping for shoot traits related to drought tolerance in barley

2014 | Keywords Association mapping, drought,
Association mapping for shoot traits related to drought tolerance in barley
The shoot traits related drought tolerance is an important for understanding drought tolerance mechanisms of the whole plant. The current research was curried out to identify the QTLs associated with shoot traits related to drought tolerance in a structured barley population grown under well-watered and drought stress conditions during the summer seasons of 2007-08., Marker data collected from all accessions ...

Selection for Drought Tolerance in Wheat Population (Triticum aestivum L.) by Independent Culling Levels

2014 | Keywords Selection wheat drought, Selection wheat drought,
Selection for Drought Tolerance in Wheat Population (Triticum aestivum L.) by Independent Culling Levels
Field experiments were carried out at Faculty of Agriculture, Sohag University, Egypt to estimate observed and expected response to selection and genetic parameters after two cycles of phenotypic selection in F2 population. Highly significant differences among F3 and F4 families under normal and drought stress conditions for no. of spikes/plant (NS), 100-Seed weight (SW), plant height (PH), days to heading ...

Additive main effects and multiplicative interaction (AMMI) and GGE-biplot analysis of genotype × environment interactions for grain yield in bread wheat (Triticum aestivum L.).

2013 | Keywords AMMI, GGE-biplot wheat,
Additive main effects and multiplicative interaction (AMMI) and GGE-biplot analysis of genotype × environment interactions for grain yield in bread wheat (Triticum aestivum L.).
The combine ANOVA analysis for grain yield of 10 wheat genotypes at 12 environments showed that bread wheat grain yields were significantly affected by E (environment), which explained 75.01% of the total treatment (G+E+GEI) variation, whereas the G (Genotype) and GEI were significant and accounted for 9.48 and 15.5% respectively. Additive main effects and multiplicative interaction (AMMI) analysis indicated that ... Read more

Physiological parameters as screening tools for drought tolerance in bread wheat lines (Triticum aestivum L.).

2013 | Keywords physiology wheat drought,
Physiological parameters as screening tools for drought tolerance in bread wheat lines (Triticum aestivum L.).
Two greenhouse experiments were carried out at the Institute of Biological Production Systems, Leibniz Universität Hannover, Germany during 2008/2009 and 2009/2010 growing seasons to study the influence of the osmotic adjustment (OA) capacity, relative water content (RWC) and specific leaf area (SLA) on tolerance to drought in 22 breeding lines, two parents and tolerant cultivar (Sahel 1) of bread wheat ...
