- •
A total of 333 introgression lines harboring chromosome segments from New Plant Type and Japonica-type cultivars in the genetic background of an Indica-type elite rice, IR 64, were characterized based on the yield components under lowland and upland cultures.
- •
And the relationships between the traits and chromosome segments introduced from the donors were clarified by association analyses using trait phenotype and genotype data of SSR makers.
- •
A total of 81 among QTL detected were found newly. These INLs and QTLs will be useful for genetic studies to identify gene(s) that modified IR 64, and as breeding materials for genetic improvement of Indica-type cultivars.
