  • Selective breeding could save trees from drought

    Trees with high wood density tend to survive better under drought conditions. In a new study on Douglas-fir tree populations, research suggests that the trees could be selectively bred for high density wood to increase resistance to drought. With predictions that the frequency of droughts could increase over the coming century, such strategies to protect tree populations could aid climate change ...

  • Breeding more uniform Nile Tilapia

    For fish farmers, uniformity of growth and body size is one of the key traits to be improved in future breeding programs. In domestic Nile Tilapia size differences among individuals are very large but the genetic background of this variability is almost entirely unknown. In a new study, published by Genetics Selection Evolution, researchers of Wageningen UR found that variability of harvest ...

  • Genome analysis helps in breeding more robust cows

    Genome analysis of 234 bulls has put researchers, including several from Wageningen Livestock Research, on the trail of DNA variants which influence particular characteristics in breeding bulls. For example, two variants have proven responsible for disruptions to the development of embryos and for curly hair, which is disadvantageous because more ticks and parasites occur in curly hair than in ...

  • Faster and better breeding of sustainable and healthy quinoa

    An international team of scientists, including quinoa breeding experts from Wageningen University & Research, published the complete DNA sequence of quinoa – the food crop that is conquering the world from South America – in Nature magazine on 8 February 2017. Quinoa is rich in essential amino acids and nutritional fibres and does not contain gluten. The crop is important to ...

  • Crop breeding gets boost from sweet potatoes

    In Uganda, the sweet potato is a major staple crop. Behind China and Nigeria, Uganda produces the most sweet potatoes in the world. Nationwide, families grow the crop to feed themselves, their livestock and to use as a source of income. Small scale agricultural operations use a large number of sweet potato varieties in their planting. These varieties are steadily being lost due to weevils, sweet ...

  • Participatory breeding program assists organic tomato growers

    Organic tomato production is growing rapidly in Midwestern states in the US, as evidenced by a USDA study that found certified organic tomato production increased more than 277% in the region from 2007-2011. The authors of a report in the September 2015 issue of HortScience say that to keep up with high consumer demand, organic tomato growers need to identify cultivars that are well-adapted to ...

  • International crop breeding programme needed for African farming

    Climate change poses a large threat to African agriculture, but there is little research on how to respond. A recent study indicates that traditional adaptation methods are not enough and international collaboration is needed in 'planned adaptation' by collecting and conserving certain crops for the future. A large proportion of the African population - mainly the poor - depend on agriculture for ...

  • Tree breeding programme to fight ash dieback recommended by study

    A recent study confirms that some European ash trees are more genetically-resistant to the devastating ash dieback disease. These individuals could therefore be selected for gene conservation and/or start a breeding programme to save the European ash. Ash trees (Fraxinus excelsior L.) across Europe are dying from a newly recognised fungal infection, Chalara fraxinea T. Kowalski. First ...

  • Biological pest control via nematode ‘breeding’ and smart fungi

    The European project BIOCOMES brings together companies and research institutes that are looking to bring new means of biological pest control to the market as a way for the EU to stimulate integrated pest management (IPM). “After two years, we are now halfway through the project and have already made some concrete achievements,” says BIOCOMES coordinator Jürgen Köhl, ...

  • 28 new rice varieties released in 2014 as scientists ensure responsive breeding for the future

    The International Rice Research Institute (IRRI) and its partners released at least twenty-eight new rice varieties to governments of eight countries in Asia and Africa in 2014. These newly-released varieties possess high-yielding and stress-tolerance traits that can help farmers overcome challenges, such as the negative effects of climate change, in their rice growing ecosystems. Some of the ...

  • Much-in-demand common sole can now be reproduced all year round

    Common sole in the North Sea only spawns in April and May. Because the next generation of this much-in-demand fish cannot be reproduced well in captivity, it cannot be raised profitably in fish farms. However, researchers at IMARES Wageningen UR managed to select the conditions for farm-raised sole in such a way that the fish started reproducing even outside the season. By selecting the right ...

  • Social genetic effect: reducing biting behaviour

    “Pigs selected on indirect genetic effects for growth display less biting behaviour,” concluded Irene Camerlink after researching Indirect Genetic Effects. The Wageningen UR researcher also has sound advice to pig farmers who want to reduce biting behaviour, such as tail biting, faster: “environment enrichment”. Indirect Genetic Effects (IGEs) are the heritable effects ...

  • USSEC’s Indian Aquaculture Team Learns Production Technologies for New Fish Species in Vietnam

    USSEC’s Southeast Asia (SEA) and Asia Subcontinent (ASC) regions teamed up to educate a team of 14 aquaculture entrepreneurs on hatchery and farm production technologies for new fish species. The focus was on a high value fish variety called the murrel, which fetches $4.50 – $ 7.00 per kilogram (whole fish), depending on the market region. This fish is easily farmed in China and SEA, ...

  • Agricultural technologies must be `appropriate`

    How an agricultural technology is generated and where it comes from — be it through local efforts or global centres —  are not as important for development as whether the product is appropriate, says development expert, Sara Delaney. 'An appropriate technology is accessible, affordable, easy-to-use and maintain, effective — and most importantly, it serves a real need', says Delaney. A ...
