Breeding New Hybrid Rice Variety with High Quality and Good Quality with Genetic Markers

A few days ago, the reporter went to Hubei Yangtze River Tuyen Seed Co., Ltd. to learn that: the world's first genetically-proprietary gene-marker-safe hybrid rice new technology was accelerated after the injection of funds from Tuen-Ye Seed Industry Technology Co., Ltd. and it has been used This project has developed a new hybrid rice variety with high quality and high quality with a gene marker. As early as 2000 when the reporter interviewed Academician Yuan Longping, the father of the world's hybrid rice, Yuan Jiashi pointed out to reporters: The problem of purity and safety of hybrid rice has always been a difficult problem that breeders want to solve, especially the light-temperature sensitive two-line system. In hybrid rice, the sterility of the hybrid rice is affected by the natural climate, so that the seed production of the two-line hybrid rice is often affected by natural disasters, and the seed purity is difficult to ensure. In recent years, it has become the focus of many breeders to solve the rapid identification of hybrid rice seed purity and its purification. In 1997, Zhang Jiwen, a researcher at the Hubei Academy of Agricultural Sciences, used nuclear radiation technology to obtain a chemically susceptible lethal rice two-line CMS mutant. Studies have shown that this mutation is controlled by a recessive monogene bel. This CMS with recessive markers can be used for rapid identification and purification of rice seedlings at the seedling stage: as long as 0.1% of the deodorant is sprayed on the leaves of the seedlings at the 3-5 leaf stage, 5 days later The self-infed seedlings of the sterile line can be killed, while the seedlings grown from true hybrids are safe and healthy. In this way, by counting the proportion of surviving and dead seedlings, the seed purity can be identified, and the purity identification cycle of hybrid seeds can be shortened from the past 120 days to about 20 days. The testing fee for each sample was reduced from the previous 30-50 yuan to less than 2 yuan. If the hybrid seeds are mixed with a small amount of sterile seeds, the farmers can completely kill the self-crossed seedlings by applying the de-doping agent in the seedlings field. It can be ensured that the hybrid rice transplanted into the field does not contain the sterile-line self-crossing seedlings. Field purity. Experts referred to this technology as "Genetic Hybrid Safe Rice Hybrid Technology". In September 1999, the research was led by Academician Zhang Xuan of the Chinese Academy of Sciences. The identification opinion was: "This research result provides a safer and more reliable way for the promotion and application of the two-line hybrid rice. The subject search proved that it has the bel gene. The flagged male sterile line of rice is the first in the country and abroad. This research is at the advanced level of similar research in the world.â€ Susan McCouch, a famous rice molecular biologist at Cornell University in the United States, calls it â€œmagic materialâ€. At the same time, two invention patents were filed in the study. In 2001, in accordance with the spirit of the document â€œEncourage Experts to Lead (Create) Enterprisesâ€ by the Ministry of Science and Technology, Zhang Jiwen, a technical inventor, was authorized to carry out industrialization and application of technology achievements in the form of scientific and technological enterprises. Need to rely on this patent application technology to breed new varieties. Zhang Jiwen had twice applied for the national â€œ863â€ project in order to obtain financial support, and he had not applied for three national funds for the transformation of agricultural achievements. If this technology is supported by the state's project grants, it must wait until the approval of the varieties. Zhang Jiwen faces the plight of lack of funds and helplessness. At the end of 2002, Hou Aimin, the chairman of Shanxi Tunyu Seed Industry Science and Technology Co., Ltd., gained insight and saw the potential enormous economic value of this new technology in the industrialization of hybrid rice. In the spring of 2003, Chairman Hou Aimin immediately appointed Zheng Wenjun, the general manager, to go to Hubei Province to contact Zhang Jiwen, a technical inventor, and reached a consensus on the cooperation between the two parties after negotiation. In order not to make mistakes in farming, let the technology be promoted and demonstrated as soon as possible, and it will be converted into productivity as soon as possible. Chairman Hou Aimin decided to invest 2 million yuan as an initial support. In September of the year, the two parties formally signed a "cooperation agreement," and the Tuen-yu seed industry made a total injection of 10 million yuan. The original inventor company increased its share of capital and established Hubei Changjiang Tunyu Seeds Industry Co., Ltd. Based on this technology, the company is committed to the industrialization of hybrid rice in the Yangtze River basin. Through two years of efforts, the Changjiang Tunyu seed industry in Hubei Province has successfully selected a series of high-yield and high-quality hybrid rice varieties with the patented technology of two or three lines. In 2004, the State Patent Office granted two invention patents. On March 18 of this year, the new variety â€œM8064S/1175â€ with this technology has passed the examination and approval in Jiangxi Province. "Tunyou No. 1", "Tunyou No. 2", "Tunyou No. 668" and other new varieties have performed well in the regional trials in Hubei Province and have entered production trials. In the production test in 2004, all plots applying this patented technology did not have mixed CMS, high uniformity, and a purity of 99%. At present, demonstration and promotion have begun in Hubei, Hunan, Anhui, Jiangxi and Zhejiang provinces. The technical personnel and farmers all over the country reflected that the patented technology rapidly identifies the purity of hybrid rice and effectively eliminates the miscellaneous strains, which enables the promotion of larger areas of the two-line hybrid rice to be based on a more secure and reliable basis, with simple operation and low cost.
