Radiation hybrid QTL mapping of Tdes2 involved in the first meiotic division of wheat
Since the dawn of wheat cytogenetics, chromosome 3B has been known to harbor a gene(s) that, when removed, causes chromosome desynapsis and gametic sterility. The lack of natural genetic diversity for this gene(s) has ...
Genetic diversity of Pyrenophora tritici-repentis in Algeria as revealed by amplified fragement length polymorphism (AFLP) analysis
Tan spot caused by Pyrenophora tritici-repentis is a major wheat disease. DNA of 61 isolates of P.
tritici-repentis from different cereal growing areas in Algeria were analyzed using amplified fragment
length polymorphism ...
Soil Testing as a Tool for On-Farm Fertility Management: Experience from the Semi-arid Zone of India
Rainfed agriculture in the dry regions is affected by water shortages. Our earlier
research showed that the deficiencies not only of major nutrients but also those of sulfur
(S) and micronutrients are holding back the ...
The Impacts of an Improved Technology Package on Production Efficiency: The Case of Wheat Farms in the Northern State of Sudan
Technical efficiency among wheat farms in the Northern State of Sudan was estimated using a
stochastic frontier production function approach. Empirical findings show that technical inefficiency is
important in explaining ...
Development of two species-specific primer sets to detect the cereal cyst nematodes Heterodera avenae and Heterodera filipjevi
Twelve Heterodera species are of major economic significance in wheat and barley. Of these, H. avenae, H. filipjevi and H. latipons are among the most important ones, and sometimes coexist. The identification of Heterodera ...
Nomadic pastoralism in southern Iran
The nomadic pastoralist system in Baft district in Kerman province is well known in
Iran for producing cashmere from Raeini goats. However, there is little information
on the production system. Interviews were carried out ...
Implications of a shift in irrigation technology on resource use efficiency: A Syrian case
The absence of adequate land leveling coupled with the ill designed traditional furrow irrigation systems
and the poor condition of drainage structures in most Syrian farms are leading to over-irrigation. A stochastic
production ...
Effect of livestock grazing on plant cover and species diversity in desert rangelands: A case study of Musawar Al Ottoria in Qatar
Protection of designated areas within rangelands is widely
considered to be the most effective and the practical way
to conserve plant diversity and maintain ecosystem
composition and structure. Thus, the effect of ...
