A marker-assisted selection (MAS) breeding program was used to improve the plant regenerability of indica rice. A significant quantitative trait loci (QTL) that is associated with the capacity for green plant regenera-tion in the anther culture of rice was mapped on chromosome 10 using recombinant inbred (RI) popu-lation from Milyang 23/Gihobyeo. The marker that was chosen to follow the QTL region was used in MAS. This marker co-segregated with the regeneration abil-ity in F2 individuals that were derived from MGRI 079/IR 36. In order to clarify the relationship between this marker and plant regenerability, the backcross population was screened with a RFLP marker. The capacity of plant regeneration of the backcross popu-lation was clearly distinguished by the marker geno-type. The development of near isogenic line (NILs) with high regenerability through MAS will save time, labor, and cost in indica rice breeding.
