Hybrid rice answer to soaring food prices
Hybrid rice, produced commercially by crossing different varieties to
attain higher yields, could hold the key to resolving a looming food
crisis, the International Rice Research Institute said yesterday.
The Philippines-based center said it was teaming up with
biotechnology firms to bolster the development of hybrids to ease
pressure on rising rice prices.
"We have before us a world in which we see rice prices increasing
dramatically," IRRI chief Robert Zeigler said in a statement.
"Since rice is the food of the world's poor, any increase in the
price of rice has a serious impact on those poor."
"There is no question that we need technologies that will improve the
productivity of rice and certainly hybrid rice is at or near the top of
the list of technologies."
Pioneered by China, the world's top rice producer and consumer,
hybrids are bred by crossing three genetically different varieties to
produce a rice plant that grows faster and produces yields of up to 20
percent higher.
The downside is that farmers need to buy new seeds to plant every
year, which raises costs, because seeds saved from the previous hybrid
crop have inconsistent yields. Grain quality can sometimes be a problem,
IRRI said.
Traditional rice varieties by contrast are self-pollinating, so the
seeds from every harvest can be used again in the next planting season.
IRRI experts say rice prices have risen close to historical levels
since 2005 because population growth has outpaced the dramatic yield
growth produced by scientific breakthroughs, known as the Green
Revolution, in the 1970s.
IRRI also said it has formed a consortium to speed up development of
hybrid rice technologies and their distribution to farmers in Asia.
Called the Hybrid Rice Research and Development Consortium, it
includes 19 private-sector biotech firms and 15 public sector
institutions from China, India, Indonesia, Iran, Malaysia, the
Philippines, Sri Lanka, and Vietnam.
"Certainly, the success of hybrid rice in China is well known,"
Zeigler said. "And the potential for hybrid rice to have an impact
across the rest of the rice-growing world is something that we all
believe is real." AFP |
