  • Genetic makeup of thousands of rice varieties placed in global seed data pool

    Genome sequences of more than 3,000 rice varieties have been placed with the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) by the world's leading rice research institute in a move boosting plans to set up a global data exchange system for crop genetic resources. The Philippines-based International Rice Research Institute (IRRI) and the Treaty (ITPGRFA) made ...

  • Drought Tolerant rice in development

    Rice production faces the threat of a growing worldwide water scarcity. Approximately, 75% of the world’s rice is grown in flooded, lowland conditions. Lowland rice crops either rely on irrigation or rain water to provide adequate growing conditions. The food security of millions of people depends on the availability of water.   Scientists at the International Rice Research Institute ...

  • Engineering rice that needs less fertiliser

    Genetic modification (GM) of crops is one of the more recent technological advances in agriculture designed to meet increasing demand for food. New research reveals that rice can be modified to use nitrogen more efficiently, thus reducing the need for nitrogen fertilisers while increasing yields. The Food and Agriculture Organization of the United Nations (FAO) has estimated that food production ...

  • GM rice `spreading illegally in China`

    Illegal genetically modified (GM) rice seeds have been found in several Chinese provinces by a government investigation, according to an environment ministry official. A joint investigation by four government departments discovered the seeds, attributing their presence to "weak management", according to the news agency Agence France-Presse (AFP). China has allowed ...

  • Genetic engineering could cut the cost of biofuels

    Plant genetic engineering could play a major part in reducing the cost of biofuel production from food crop wastes such as rice straw or from non-food crops such as willow and poplar. A recent study suggests further research is needed to develop plants that are better suited for biofuel production, through genetic modifications. According to the study's author, biofuels have the potential to ...

  • Using genetic mapping to save wheat production

    Stem rust disease has the potential to devastate wheat production worldwide. In the 1950s, large epidemics spread across North America and through other parts of the world. Developing a stem rust resistant gene stopped the spread of the disease. In 1999, a new race of stem rust was discovered in Uganda and identified as Ug99. Previously developed stem rust resistant genes are no longer effective ...

  • Fostering closer collaboration across the rice value chain

    With increasing challenges in agriculture, and 2015 in particular being a difficult year for farmers in ASEAN, rice farmers need access to technologies to help them increase yields and efficiency. From October 14 to 16, over 100 policymakers and rice experts from across ASEAN countries gathered at the ASEAN Rice Future Forum in Vietnam to discuss how public-private and value chain partnerships ...

  • Genetically Modified Crop Industry Continues to Expand

    One of the familiar narratives for the promotion of genetically modified (GM) crops is that they have the potential to alleviate poverty and hunger. But the real impacts of GM crops deserve closer assessment, writes Wanqing Zhou, research associate in the Food and Agriculture Program at the Worldwatch Institute, in the Institute’s latest Vital Signs Online article ...

  • Genetic change could make crops thrive on salty soils

    Scientists have genetically modified plants to tolerate high levels of salt — offering a potential solution to growing food in salty soils. The researchers inserted a gene to remove salt — in the form of sodium ions — from water taken up by the plant before it reaches the leaves, where it does most damage. The research was published in The Plant Cell this month (7 July). High salinity reduces ...

  • `Waterproofing` gene may also protect rice from droughts

    Farmers facing extreme weather conditions associated with climate change could benefit from the finding that a gene that 'waterproofs' rice plants also appears to protect them from drought. The Sub1a gene, which naturally occurs in some low-yielding varieties in India, was discovered in the 1990s at the International Rice Research Institute (IRRI), in the Philippines. Subsequent research showed ...

  • Upcoming IRRI young rice scientist to present research on association mapping of bacterial blight resistance at IRC2014

    Christine Jade Dilla-Ermita of the International Rice Research Institute (IRRI) has been selected as one of the 29 Young Rice Scientists (YRS) awardees who will present their research at the 4th International Rice Congress (IRC2014) in Bangkok, Thailand on 27 October-1 November 2014. “To share my research on the genome-wide association analysis of bacterial blight resistance ...

  • RRI, STRASA and PAU hold workshop on major rice pests and diseases in Southeast Asia

    STRASA (Stress Tolerant Rice for Africa and South Asia), the International Rice Research Institute (IRRI), and Punjab Agricultural University (PAU), Ludhiana, India held a two-day review and planning workshop on major rice pests and diseases in Southeast Asia at Punjab Agricultural University on 15-16 September. Twenty cooperators (13 from India , 3 from IRRI, 3 from Bangladesh. and 1 from Nepal) ...

  • 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 ...

  • U.N. Clean Development Mechanism Approves Arcadia Biosciences Methodology, Links Carbon Credits to Crop Genetic Improvements for First Time

    Arcadia Biosciences, Inc., an agricultural technology company focused on developing technologies and products that benefit the environment and human health, today announced that the Executive Board of the Clean Development Mechanism (CDM) of the United Nations Framework Convention on Climate Change has approved Arcadia’s methodology to allow farmers to earn carbon credits from reduced ...

  • Crops and Weeds: Global climate change`s first responders

    A team of Agricultural Research Service (ARS) plant physiologists is studying how global climate change could affect food crop production--and prompt the evolution of even more resilient weeds. Lewis Ziska, Richard Sicher and Jim Bunce all work at the ARS Crops Systems and Global Change Laboratory in Beltsville, Md. Over the past several years, the three scientists have conducted research on a ...

  • 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 ...

  • Carbon credits to be used to fund GM food crops

    US biotech firm Arcadia Biosciences has announced a plan to help fund the planting of genetically modified rice with carbon credits. The company will work with the Chinese government to give farmers who plant their crops carbon credits, which they can then sell on the global carbon trading market. Arcadia is touting its GM rice as a greener alternative to the regular crop. The plant has had a ...

  • Biotechnologies should benefit poor farmers in poor countries

    The focus of modern and conventional biotechnologies should be redirected so as to benefit poor farmers in poor countries and not only rich farmers in rich countries, FAO said today. 'Modern and conventional biotechnologies provide potent tools for the agriculture sector, including fisheries and forestry,' said Modibo Traore, FAO Assistant Director-General, addressing the international technical ...

  • Asia–Pacific Analysis: Launching a second Green Revolution

    Feeding South-East Asia's rapidly growing population requires a second Green Revolution, says Crispin Maslog. The Day of Seven Billion was proclaimed by the United Nations Population Fund (UNFPA) on 31 October 2011 as a historic milestone — the day the world's population reached seven billion people. And the world is on a steep growth curve for the rest of this century. ...
