China to up grain production with japonica rice
China plans to step up cultivation of japonica hybrid rice to increase grain production to ensure food security.
The development of japonica hybrid rice has huge potential in China as the nation is seeking new increase areas of grain products, the state media quoted an official with the Ministry of Science and Technology (MOST) as saying.
A MOST official in charge of rural and social development said the hybrid rice technology developed by Chinese scientists are widely used in the world while the japonica hybrid rice technology are yet to be promoted.
China now grows about 40 million acres of hybrid rice to feed more than 70 million people while the japonica rice only accounts for five per cent of all the hybrid rice growing areas, he said.
China has planned to raise the proportion to 30 per cent by 2010 to realise an annual japonica rice production of three billion kilograms, the official said.
Chinese scientists have made breakthroughs in cultivating japonica rice in recent years. The new varieties named "Changyou" which were developed by Changshu Agricultural Technology Institute have passed national tests.
