Ancient crops preserved for future generations in Arctic seed vault
Varieties of one of the world's most important staple crops will be stored for perpetuity deep in the Arctic ice today. José Graziano da Silva, Director-General of the Food and Agriculture Organization of the United Nations (FAO) is joining scientific experts and delegations from Peru, Costa Rica and Norway to witness a ceremony here this afternoon that will help to preserve these vital ...

Cover Crops Add to Farm Sustainability
A potentially record-setting U.S. corn harvest is underway. Many farmers can attribute the use of cover crops as one of multiple best management practices (BMPs) that help them increase yield year after year. Combined with BMPs of The Fertilizer Institute’s 4R Nutrient Stewardship program that promotes the application of nutrients at the right source, right rate, right time and right place, ...

Time is ticking for some crop`s wild relatives
New edge of extinction research is creating a revival of conservation and interest in what these old plants mean to the future Experts and photos available on this topic! A botanist brings a species of alfalfa from Siberia, to the United States. His hope? The plant survives, and leads to a new winter-hardy alfalfa. But what also happened during this time in the late 1800's, isn't just a story ...

New research reveals challenges in genetically engineered crop regulatory process
Experts are available for interviews on this topic! A new innovation can completely reshape an industry-- inspiring both optimism and debate. The development of genetically engineered (GE) crops in the 1980's ignited a buzz in the agricultural community with the potential for higher crop yields and better nutritional content, along with the reduction of herbicide and pesticide use. GE crops ...

Fight against wheat rust needs sustained investment
Developing countries need help with crop surveillance and the development of strains resistant to wheat rust, say agricultural research leaders. Today's food security situation is being worsened by strains of wheat rust disease that are emerging more frequently and spreading much faster and to new areas — changes fuelled by climate change and conducive environments in increasingly fragile ...

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 ...

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 ...

Lima beans domesticated twice
Lima beans were domesticated at least twice, according to a new genetic diversity study by Colombian scientists. Big seeded varieties known as “Big Lima” were domesticated in the Andean Mountains, while small seeded “Sieva” and “Potato” varieties originated in central-western Mexico. The researchers also discovered a “founder effect,” which is a ...

Keeping tabs on the next generation of transgenic crops
A team of government and university crop scientists from across Canada has developed a scientific framework for monitoring the release of second-generation genetically modified crops. The framework is designed to assess the risks of novel genes entering wild populations. First-generation genetically modified (GM)/transgenic crops with novel traits have been grown in a number of countries since ...

Genetics not enough to increase wheat production
The deep gene pool that has allowed wheat to achieve ever increasing gains in yield may be draining. Crop scientists estimate that 50% of the gain in wheat production over the past century has been due to breeding. According to a new study, however, that improvement has been slowing since the late 1980s, with little chance that future increases in yield can be met by breeding efforts alone. The ...

Turfgrass that wears down and springs back up
Kentucky bluegrass, a turfgrass frequently grown on sports fields, is more tolerant to wear during the spring compared to other seasons, and shows better recovery during spring, according to research from Rutgers University. The study also identified which varieties of bluegrass showed the most wear tolerance. Researchers Bradley Park, T.J. Lawson, Hiranthi Samaranayake, and James A. Murphy, ...

Increasing the shelf-life of cassava
Crop scientists have identified several genetic mechanisms to improving the shelf-life of cassava roots. Long an unsolvable problem, the research has the potential to benefit the poorest of the poor, widening and strengthening the markets for cassava, reducing marketing costs, and losses along the marketing or value addition process. The research team, led by Hernán Ceballos at the ...

Cotton’s global genetic resources
A multinational collaborative effort among cotton scientists produced a report on the status of the global cotton genetic resources. According to the report, cotton production relies primarily on two species, with 48 other species catalogued in the various seed collections that have largely been poorly characterized and under-utilized in crop improvement efforts. Based on the findings of this ...

Maize seedlings predict drought Tolerance
Scientists have developed a new method for measuring drought tolerance in maize. By comparing the shoot-to-root ratio in seedlings stressed by low water, scientists can predict whether a plant has the right mix of genes for adapting to drought conditions. The ideal drought-resistant maize should have a higher ratio of root surface area compared to leaves and stems. Developing enough adult plants ...

Peanuts: more genetically diverse than expected
Virginia-type peanuts, the big ones sold in the shell or used in cocktail nut mixes, are more genetically variable than previously assumed, according to a new study from North Carolina State University. Before now, cultivated peanuts showed very little variability for molecular markers, leading some to conclude that there was virtually no genetic variation in the species. However, anyone who has ...

Scientists find four-leaf clover gene
Ending a period of “bad luck” for clover researchers, scientists report finding the gene that turns ordinary three-leaf clovers into the coveted four-leaf types. Masked by the three-leaf gene and strongly influenced by environmental condition, molecular markers now make it possible to detect the presence of the gene for four-leaves and for breeders to work with it. The results of the ...

Soil gives away soybean pathogen’s presence
New research reveals that soil pH is a useful guide for farmers and agronomists to detect and manage soybean cyst nematode, a devastating soybean pathogen. The investigation uncovered a relationship between high soil pH, which is already outside the ideal growing conditions for soybean, and high populations of cyst nematodes. Scientists from Iowa State University and University of ...

Method to differentiate open pollinated varieties of maize developed
Open pollinated varieties of maize are going to be easier to distinguish from each other, thanks to scientists at the International Maize and Wheat Improvement Center (CIMMYT) in Africa and Mexico. They have developed a new technique to differentiate the genes of one open pollinated variety from another, particularly important to African farmers, most of whom do not plant hybrid varieties. The ...
