After nearly 10 years of scientific and technological research, Zhu Qisheng, a researcher at the Anhui Academy of Agricultural Sciences, invented a rice restorer (father) preparation method that contains the sensitive gene for the herbicide Bendazosone, and adopted this method for the first time to develop a hybrid rice “mixed broadcast†system. In this way, the hybrid superior green hybrid rice combination "Lvyou No. 5" was selected for mechanical harvesting. On September 9th, the Anhui Academy of Agricultural Sciences invited peer experts to conduct on-site assessments of “mixed-sowing†seed production. The measured yield of “Lvyou 5†was 339.9 kg, which was 27.8% higher than that of conventional methods. Experts commented that this is a new breakthrough made by China's hybrid rice seed production technology. The current hybrid rice seed production technology in China is completely dependent on manual operation from seeding to harvesting. Parents are planted in stages, the father is planted first, the mother plant is reared, and the procedure is complicated. The entire seed production process requires sufficient labor force as a guarantee and is only suitable for labor. Intensive rural extension applications, large farms can not be produced because of the lack of sufficient labor force. The invention of Zhu Qisheng will fundamentally change this status, and the production of seed production will also be greatly improved. In June of this year, his invention has been granted by the State Intellectual Property Office. This hybrid rice seed production technology is a method in which the rice parent (recovery line) and the female parent (CMS line) carrying the Bendazosone sensitive gene are evenly mixed in a certain proportion and can be planted once and can be grown like conventional rice. Field cultivation and management can be used for throwing, machine inserting, and live broadcasting, greatly simplifying the planting process. When the parents entered the flowering stage and naturally completed the pollination, the herbicide Bendazon was sprayed into the field in a timely manner. The parent of the rice carrying the Bentazon sensitive gene met with Bentazon and soon died, but the mother who did not carry the gene This article is safe and sound, normal growth until maturity, and finally mechanized harvesting.
