摘要: A mutant, which derived from the restorer line Jinhui10 treated with EMS, showed completely yellow green leaves, and it had low chlorophyll content and poor agronomic characteristics during the growing stage. The F, plants from the cross between normal x the mutant showed normal green leaves, and the segregation ratio of normal to yellow green leaves was 3: 1 in F-2 population. It indicated that the trait was controlled by a single recessive nuclear gene, temporarily designated as ygl3. The gene ygl3 was mapped between RM468 and RM3684 with genetic distances 8.4 cM and 1.8 cM on chromosome 3. This result would be used as genetic information for fine mapping and map-based cloning of ygl3 gene.
