rid rice strains began in 1996 as part of China's major efforts to ensure food security.
So far, the country has approved 96 varieties of new super rice strains, with planting areas reaching 7.4 million hectares, or nearly a quarter of the country's rice fields, according to the Ministry of Agriculture.
In November, a super rice strain called Yongyou 12 produced a harvest of 14.38 tons a hectare at an 8.5-hectare demonstration base in Ningbo, Zhejiang province.
