Effect of genotypes and culture media on embryogenic callus induction and plantlet regeneration from mature embryos of durum wheat
In wheat, immature embryos are the most widely used explant to initiate cultures, but they are
inconvenient due to their temporal availability and production requirements. Mature embryos are easily stored
and are readily ...
Association Mapping of Resistance to Yellow Rust in Winter Wheat Cultivars and Elite Genotypes
Yellow (stripe) rust, caused by Puccinia striiformis
f.sp. tritici (Pst), is a destructive disease of
wheat (Triticum aestivum L.) all over the world,
particularly in the Central and West Asia and
North Africa (CWANA) ...
Characterisation and mapping of gene Lr73 conferring seedling resistance to Puccinia triticina in common wheat
A gene conferring seedling resistance to Puccinia triticina was mapped to chromosome 2BS in the wheat Morocco. The gene was shown to be distinct and was therefore designated Lr73.
Abstract
The wheat genotype Morocco, ...
Predicting resistance to stripe (yellow) rust (Puccinia striiformis) in wheat genetic resources using focused identification of germplasm strategy
Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a major wheat disease that can inflict yield losses of up to 70% on susceptible varieties under favourable environmental conditions. The timely identification ...
GM Crops, Organic Agriculture and Breeding for Sustainability
The ongoing debate about the use of genetically-modified (GM) crops in
agriculture has largely focused on food safety and genetic contamination issues. Given that
the majority of GM crops have been produced to respond to ...
Quantitative inheritance of resistance to Septoria tritici blotch in durum wheat in Tunisia
Septoria tritici blotch, causal agent Mycosphaerella graminicola (Fuckel) J. Schröt. (anamorph: Zymoseptoria tritici Desm.),
is the major foliar disease of wheat (Triticum aestivum L.) in Tunisia causing frequent epidemics ...
Effects of Root Water Uptake Efficiency on Soil Water Utilization in Wheat (Triticum aestivum L.) under Severe Drought Environments
Improving wheat production in drought-prone areas is the key to meet the increasing global demand. The importance of root traits, especially, the structural traits such as root volume and rooting depth, has been well ...
Assessment of on-farm diversity of wheat varieties and landraces: Evidence from farmer’s fields in Ethiopia
Analysis of spatial diversity, temporal diversity and coefficient of parentage (COP) were carried out along with measurements of agronomic and morphological traits to explain on-farm diversity of modern varieties or landraces ...
Selection of morpho-physiological traits associated with terminal drought stress tolerance in durum wheat (Triticum durum Desf.) genotypes
In order to study the response for
drought induced at critical stages of grain filling
of 8 durum wheat genotypes, five Tunisian
landraces (Biskri, Mahmoudi, Agili, Chili and
Jeneh khotifa) and three improved genotypes
(Karim, ...
Effect of zero tillage system, seeding rate and row spacing on growth, yield and its components of bread wheat in moderate rainfall area in ninevah province.
A RCBD factorial experiment with 3 factors in Split Split Plot design was conducted in 2011-2012 agricultural season at Telkief location in rainfed field (183.5 mm–very drought season) to evaluate the effect of tillage ...
