Xinhua Guiyang, September 22 (Reporter Zhou Lotus) National Hybrid Rice Research Center, Chinese Academy of Engineering, said Yuan Longping 22, said in Guiyang, rice still has great yield potential, super hybrid rice yield of 1000 kg is attainable.

Yuan Longping 22, held in Guiyang, the “Super Hybrid Rice Breeding” Looking at the report, said prospects for super hybrid rice, endless scientific and technological development, rice production still has great potential, 2.5% of the light energy utilization by the calculation, the yield of rice in Hunan season up to 1500 kg, we will take the plant type with excellent breeding, strong inter-subspecific heterosis and high efficiency of C4 (C4) gene three-pronged technical route, the fourth in super hybrid rice in 2020 1,000 kg per mu goal can be achieved.

Yuan Longping said that in 2000, China has bred a few pioneer super hybrid rice combinations, the production reached the Ministry of Agriculture to develop “Chinese super rice,” the first target, in recent years to promote the area About 10000000-2000 acres, an average of about 550 kilograms per mu; the second phase of super hybrid rice, 800 kg per mu in 2004, targets a year ahead, 2006 to promote, an area of ??more than 500 acres planted last year, the average acres produced about 600 kilograms, compared with the first phase of super hybrid rice is 50 kg/mu; has been approved and started the third phase of super hybrid rice breeding program, one quarter of super hybrid rice production in large-scale demonstration of the target is 900 kg/mu, has recently breakthrough Longhui County in Hunan, 108 acres demonstrative average yield reached 926.6 kg.
