Strategy for breeding of WH6725. WH421 (genotype: Xa4Xa4,Xa21Xa21) was used as the recurrent female line for crossing and backcrossing. The number of positive plants over the number of total plants screened are indicated in each generation. For gene pyramiding, four F2 plants containing homozygous alleles at all loci were obtained in the F2 population and one of the plants, F2-281, was designated as Wanhui 6725 (WH6725). The genotypes of Xa4 and Xa21 genes are only shown in WH6725 but not in other generations
