New super rice likely to boost output by 25 pc
WASHINGTON. Oct 24: A new super rice strain could boost rice production by 25-per cent, enough to feed an additional 450 million people a year, the International Rice Research Institute reported, says AFP.
Rlce^ the major crop for developing nations, feeds half of the world’s population. However, demand is slowly outstripping production.
The "super rice" has the potential to increase production while using the same amount’ of land as current strains, an important factor in rapidly developing Asian nations, experts said.
This rice will go a long way toward feeding the world's people through the next century. especially in Asia where rice is the staple.\ said Ismail Serageldin. Chairman of the Consultative Group on International Agricultural Research (CGIAR), which the IRRI and 16 other scientific centres are part of.
Super rice and other, global agricultural research projects are being discussed at the CGIAR International centres week in Washington from October 24 to 28.
Development - of the new variety also, comes as rice production faces a host of pressures.
"It’s not possible to step up rice produetion dramatically by planting on new land," Serageldin said.
Some of the best rice land is being lost to population growth and.rapidly expanding yrban centres, while remolding virgin lands are not suited for rice." he added.
In addition to-these factors, ^ome 10 per cent of traditional
rice farming land is showing signs of fatigue.from monoculture farming practices.
According to IRRI figures, super rice production could reach 12.5 tonnes per hectare (2.47 acres) up from conventional strains producing 10 tonnes per hectare.
If the super rice were planted widely it could produce 100 million more tonnes per year, providing some 450 million people with the annual average consumption of 200 kilograms (440 ppunds), the IRRI said.
With population figures predicted to hit 8.3 billion people by the year 2025 from the present ’5.5 million.-the new variety may prove pivotal.
"We don’t - know yet how many people will live on earth in the middle of the next century. but we know that we have to produce at least, more than twice the food we harvest today." said Klaus Lampe. Director General of the Philippines-based IRRI.
"We don't have the technology yet to make that happen. The new generation of rice, however, is a very important building block to achieve this goal." he added.
The new super rice comes from strains selected from some 80.000 rice samples the IRRI maintains.
After five-years of development. the end yield produced prototypes with thick and sturdy stems as well as thicker, darker green and erect leaves to achieve the increased yield.
Researchers will now try to breed enhanced resistance to pest’s and disease as well as culture different tastes and cookingqualitles. ■
