湖南自1967年从自然界发现不育株后,近几年用大量品种与不育株杂交,目前不育系基本稳定,恢复系在栽培品种中大量存在,主要是保持系尚未稳定,出现分离。因此,他们的工作重点是解决保持系的问题。现在拟通过1.用大量的其它品种与不育系进行单株成对杂交;2.用可能的保持系继续与不育系测交;3.按照遗传学理论假设,用人工制造等三种
After the discovery of sterile plants from nature in 1967, Hunan has crossed with a large number of sterile plants in recent years. At present, the sterile lines are basically stable, and the restorer lines are abundant in cultivars. The main reason is that the maintainer lines have not been stabilized and are separated. Therefore, their focus is to solve the problem of maintaining the department. Now it is proposed to adopt 1. To use a large number of other varieties and sterile lines for single-pair hybridization; 2. Use the possible maintainer to continue with the CMS line; 3. According to the genetic theory hypothesis,
