China is seeking to improve its seed industry over the next decade to ensure grain stocks growth.

The five main staples - rice, wheat, corn, soy and potato - and 15 varieties of cash crop have been listed as important fields for cultivating new varieties by 2020, according to a development plan by the General Office of the State Council.

Production bases for staple seeds will be established in north-western and south-western regions, as well as Hainan province, by 2015, the plan says.

China recorded grain output of more than 589 million tonnes in 2012. It was the ninth consecutive year of increased grain harvests, the Ministry of Agriculture said.
