Meta-analysis of QTL associated with fusarium head blight resistance in wheat
Quantitative trait loci (QTL) associated with resistance to Fusarium head blight (FHB), which is mainly caused by Fusarium graminearum Schwabe [telomorph: Gibberella zeae Schw. (Petch)], have been identified in wheat (Triticum aestivum L.) from different countries. Due to the differences of genetic backgrounds and analysis methods, the linked marker and significance levels of QTL are not ...

Better photosynthesis for a better world?
There’s no question that plants are better than most other life forms at converting carbon dioxide and sunlight into the sugars that form the basis of our global food web — and eventually, humans’ entire food supply. But fact of the matter is, with conversion rates hovering around 2 percent for our best crop fields, they’re by no means great. Even a slight increase in the ...

New approaches are needed for another Green Revolution
Twenty-first century agriculture needs low-input advances like the System of Rice Intensification, says Norman Uphoff. According to the principle of diminishing returns, continuing to produce something in the same way, with the same inputs and technology, usually becomes less productive over time. This appears to apply to agriculture's 'Green Revolution', as yield improvement has slowed in ...

Optimization of the marker-based procedures for pyramiding genes from multiple donor lines: III. multiple-gene assemblage using background marker selection
Constructing high-degree gene-pyramided lines has important practical implications; such lines could be used for multiple purposes, for example, as a high-powered breeding stock line, a material line for characterizing multigene interactions, or a market variety as it stands. Effectiveness of two typical marker-based schemes for constructing such lines, named AF (gene assemblage first) and BF ...

Effects of low-dose irradiation on two plant models: Stipa capillata and Pisum sativum
Plants are useful models for assessing the effects of radiation. We describe a short synthesis of our more recent results: radio-induced oxidative stress – our data suggest in chronically irradiated seeds of Stipa capillata a natural selection of the most adapted genotypes characterised by the capacity of induction of enzymes involved in the defence against radioactive stress; growth, ...

Ontario Horticulture Research Priority Report 2016
Sector Consultation The Ontario Fruit and Vegetable Growers Association partnered with Vineland to host a research strategy workshop in November 2014 with the goal of defining the top five research priorities for each crop group. Grower organizations were invited to nominate two representatives to participate on their behalf and a number of researchers from relevant fields were invited to ...
