Title [Utilization of a microsatellite marker to identify rice blast resistance gene in two segregating populations].
The microsatellite (SSLP) marker RM262, which is tightly linked to the blast resistance gene Pi-d(t) in rice, provides means to conduct marker-aided selection in a rice breeding program. The objective of this study was to investigate the ability of this marker to select the blast resistance gene, Pi-d(t), in two crosses for rice blast resistance breeding. The products with amplified the microsatellite primers were polymorphic between the three varieties examined. To examine the power of the identified microsatellite marker in predicting the Pi-d(t) locus, we determined the genotypes of the two F2 populations at the Pi-d(t) locus by performing progeny testing for the disease respones. The results indicated an accuracy of more than 98% in identifying the resistant plants in both populations. Therefore the microsatellite marker can be utilized in marker-assisted selection and breeding for new varieties with blast resistance.
