Relationships of grain delta C-13 and delta O-18 with wheat phenology and yield under water-limited conditions
Stable carbon isotope composition (delta C-13) of dry matter has been widely investigated as a selection tool in cereal breeding programmes. However, reports on the possibilities of using stable oxygen isotope composition ...
Soil carbon stocks in conservation agriculture systems of Southern Africa
In view of the importance of soil carbon (C) and the scarce data on how conservation agriculture might influence its accumulation in Southern Africa this study presents data from 125 on-farm validation trials across 23 ...
Why Self-fertilizing Plants Still Exist in Wild Populations: Diversity Assurance through Stress-Induced Male Sterility May Promote Selective Outcrossing and Recombination
Climate change creates challenges for wild species, but plants have survived and adapted
to similar changes in their evolutionary past. Most plants were originally outcrossing, one theoretical
genetic reason being that ...
Process of development of network of on-field, multiscale innovation and validation sites
This report includes the description of the main actors of the networks that have started around the CLCA project in LAC, the characterization of some of the incipient relationships between them, and the physical ...
Diversity analysis of 80,000 wheat accessions reveals consequences and opportunities of selection footprints
Undomesticated wild species, crop wild relatives, and landraces represent sources of variation for wheat improvement to address challenges from climate change and the growing human population. Here, we study 56,342 ...
Yield gain due to fungicide application in varieties of winter wheat (Triticum aestivum) resistant and susceptible to leaf rust
In three independent experiments in Turkey and Kazakhstan, winter wheat germplasm with variable degrees of resistance to leaf rust was subjected to fungicide protection. The yield loss of genotypes susceptible to leaf rust ...
CAC News No 25. July-September 2005
News from CGIAR Collaborative Research Program for Sustainable Agricultural Development in Central Asia and the Caucasus (CAC) covering the countries: Armenia, Azerbaijan, Georgia, Tajikistan, Turkmenistan, Kazakhstan, ...
Soil salinity management on raised beds with different furrow irrigation modes in salt-affected lands
Mismanagement of irrigation water and the ensuing secondary salinization are threatening the sustainability of irrigated agriculture especially in many dryland regions. The permanent raised-bed/furrow system, a water-wise ...
CGIAR germplasm health units apply a systems approach to germplasm seed health protection for conservation and safe international distribution
Germplasm seed exchange from CGIAR genebanks and breeding is important to global
agricultural research and development programs. Seed as a pathway for pest spread is an
inherent risk for international seed exchanges. ...
