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 ...

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 ...

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, ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

The dire need to support ‘orphan crop’ research
In spite of debate over its definition, the term ‘orphan crops’ refers to crops that are under-researched and underfunded due to their limited importance in the global market. These include cereals, legumes, vegetables, root crops, fodder crops, oil crops, fibre crops and medicinal plants that are largely indigenous to Africa, Asia and Latin America. They are characterised by their ...

Steady increase in incidents of low levels of GM crops in traded food and feed
The increased production of genetically modified crops around the globe has led to a higher number of incidents of low levels of GMOs being detected in traded food and feed, FAO said today. The incidents have led to trade disruptions between countries with shipments of grain, cereal and other crops being blocked by importing countries and destroyed or returned to the country of origin. The ...
