Description

technical field

[0001] The invention relates to a method for producing late-maturing three-line hybrid rice seeds, which belongs to the technical field of utilization of rice heterosis in crops. Background technique

[0002] At present, the main ways to utilize heterosis in indica rice at home and abroad include the three-line method (sterile line, maintainer line, restorer line) based on nucleoplasmic interaction such as the wild type or red lotus type, and the two-line method based on light and temperature sensitive conditions. Law. Since 1973, when my country was the first in the world to realize the three-line combination of indica hybrid rice, my country has maintained a world-leading level in the field of rice heterosis utilization research. In the 1970s and 1980s, my country's production of Shangshanyou system and Weiyou system three-line hybrid rice developed rapidly; in the 1990s, my country's Shanyou, Weiyou, Gangyou, IIyou, Youyou, Boyou A total of hundreds of th...
