KUNMING, Sept. 11 (Xinhuanet) -- Chinese agronomists have cultivated new species of "super rice," the Super Rice II YOU 28, with average per hectare yield reaching a record high of 18,449.55 kilograms.

    The new species of high-yield hybrid rice was sown in March, planted in May and harvested on September 10 in Taoyuan Village, Yongsheng County of south China's Yunnan Province, with fertility period lasting 192 days.

    Ma Liangyong, a research fellow with the China Rice Rsearch Institute, said that the species of Super Rice II YOU 28, with strong stalks and large ears, will play significant roles in promoting grain production both in China and in the world. Enditem
