Phenotypic and genotypic status of 265 RILs assessed by bioassay against three BB races screened with four markers.
| Phenotypic Status | Genic Status * | RILs with Different Genes | |||
|---|---|---|---|---|---|
| Xa4 | xa5 | xa13 | Xa21 | ||
| Single locus | 41 | 23 | 29 | 25 | |
| Resistant | Double loci | 19 | 20 | 19 | 22 |
| Triple loci | 29 | 18 | 27 | 28 | |
| Quadruple loci | 11 | 11 | 11 | 11 | |
| Susceptible | No amplification | 165 | 193 | 179 | 179 |
| Total | 265 | 265 | 265 | 265 | |
* Single locus: presence of any one gene out of targeted four pyramiding loci; Double loci: presence of any 2 genes out of targeted four pyramiding loci; Triple loci: presence of any 3 genes out of targeted four pyramiding loci; and Quadruple loci: presence of any 4 genes out of targeted four pyramiding loci.
