The milestone advancement was pioneered by scientist Guo Sandui and his team at the Chinese Academy of Agricultural Sciences. The breakthrough won wide acclaim from officials and experts over the weekend. Building on his success of insect-resistant, genetically-modified cotton, of which 2.3 million hectares was planted this year, Guo's research team in 1999 started to work out a molecular breeding system for hybrid cotton. After years of hard work, Guo, the "father of Chinese Bt transgenetic cotton," was able to have his "Yinmian 2" cotton strain approved by the National Crop Cultivar Assessment Committee, which gave the go-ahead for its commercialization, according to the Ministry of Agriculture. The "three-line hybrid cotton with insect-resistant gene," if planted on the 3.33 million hectares of land where it is fit to grow, will theoretically increase output by 1 million tons each year.That amounts to what conventional strains may be able to yield on 666,600 hectares, which is the equivalent size of all the cotton fields in the Yangtze River Delta, a leading cotton producer in China, Vice-Minister of Agriculture Fan Xiaojian said on Saturday. With this remark, Fan was apparently pointing to the technology's potential power to ease the country's land allocation conflict between grain and cotton crops. The "three lines" refer to the male-sterile, maintenance and restorer lines in cotton breeding. Through genetic engineering and conventional breeding, Chinese scientists have manipulated these lines to ensure a hybrid cotton strain that maintains and multiples hybrid heterosis, leading to high quality and high yields, said Zhang Rui, one of Guo's aides.
In addition, the strain's insect resistance efficiency is more than 90 per cent, Zhang said. Guo's "Yinmian 2" and other strains in the pipeline will enable China to use less acreage to reach its cotton production goals, leaving more cropland for grain production, Fan said.Fan and a group of government officials and experts inspected Guo's experimental base in Beijing's Pinggu District on Saturday. The United States began "three-line hybrid cotton" research in 1948, but has failed to find a solution to ensure a desirably high yield of hybrid cotton, let alone a hybrid one with pest-resistance. Other major cotton growers, such as India, develop hybrid cotton through a laborious inefficient manual breeding method, according to Guo. Yuan Longping, the world's "father of hybrid rice," said on Saturday he had visited both the US and India to see their hybrid cotton breeding in the 1980s and 1990s. "I believe China's 'three-line hybrid cotton with insect-resistant gene' is really a world-leading breakthrough," Yuan told China Daily. "Even in its initial stage, it can boost cotton production by 25 per cent. This is a great feat." Compared with his "hybrid rice" which promises to increase grain output by up to 20 per cent, Yuan said Guo's hybrid cotton is well on course to increase output by 30 per cent in the years to come. The senior scientist urged the ministries of agriculture, science and technology as well as the National Development and Reform Commission to shore up investment and spread the technology nationwide to benefit farmers.
