Selection of new high yield potential bread wheat lines resistant to Hessian fly, Mayetiola destructor (Say), in Morocco
Wheat (Triticum sp.) is the main staple food of the Moroccan population. However, the
crop is attacked by several pests and diseases. Hessian fly is the most serious pest, causing
an average yield loss of 30% yearly. In ...
Impacts of International Wheat Improvement Research
Wheat is a major source of calories and protein for consumers in developing countries. The “Green Revolution” improved the national food security and welfare of the poor in developing countries in the second half of the ...
Measurement of the total factor productivity and its determinants: the case of the wheat sector in Tunisia
The main objectives of the current study are to quantify the Total Factor Productivity (TFP) growth of durum wheat sector in Tunisia and to identify its main determinants. The Malmquist index approach was applied for the ...
Fast-forward genetics by radiation hybrids to saturate the locus regulating nuclear–cytoplasmic compatibility in Triticum
The nuclear-encoded species cytoplasm specific (scs) genes control nuclear–cytoplasmic compatibility in wheat (genus Triticum). Alloplasmic cells, which have nucleus and cytoplasm derived from different species, produce ...
Control of Helminthosporium leaf blight of spring wheat using seed treatments and single foliar spray in Indo-Gangetic Plains of Nepal
Four fungicides for seed treatments and one as foliar spray were tested in replicated field experiments in
a strip plot design to determine the effect of fungicides on Helminthosporium leaf blight (caused by
Cochliobolus ...
Impacts of Improved Supplemental Irrigation on Farm Income, Productive Efficiency and Risk Management in Dry Areas
This paper provides empirical evidence that improved supplemental irrigation
(ISI) can be justified on both environmental and economic grounds. Results
of a stochastic frontier model which explicitly and simultaneously ...
Sources of resistance in durum wheat and its wild relatives to Russian wheat aphid (Hemiptea: Aphididae)
Russian wheat aphid (RWA), Diuraphis noxia (Kurdjumov), is a serious pest of cereals in
many parts of the world, particularly in dry areas. As limited resistance sources to this pest
were previously identified in durum ...
Race structure of Pyrenophora tritici-repentis in Morocco
The virulence of 135 single-spore isolates of Pyrenophora tritici-repentis, collected from durum wheat fields representing most of the major agro-ecological zones of Morocco from 2013 to 2015, was assessed on six international ...
Crop breeding for the development of climate resilient crops: Approaches at ICARDA
Crop production has been challenged by abiotic and biotic constraints since its inception. However, the magnitude and intensity of these stresses are increasing dramatically due to climate change causing recurrent droughts, ...
Gene Flow as a Source of Adaptation of Durum Wheat to Changing Conditions Including Climate Change: Double Gradient Selection Technique
Fluctuating environments are recurring scenarios in dryland agriculture with detri- mental effects to crop production such as durum wheat crop that could lead to losses in yield. The dryland Mediterranean type of environment ...
