Genetically pure CMS line (A-line) is essential to generate pure hybrid in order to harness the yield heterosis in rice. Conventionally, seed purity testing is carried by grow-out test (GOT), which has many limitations. Seed purity assessments based on molecular markers, reduces the time required for analysis significantly. However, it is very tedious since at least 200-400 seeds/seedlings are needed to be analyzed individually. An assay based on bulked-seed and molecular markers will be an ideal system. Keeping these points in view, in the present study, a co-dominant mitochondrial marker was used to test the purity of bulked parental line (A-line) seed utilising capillary electrophoresis system in a Genetic analyser. The results indicate that this method is very simple, accurate and can be used to test purity of large number of samples rapidly in a cost effective way compared to GOT and conventional molecular marker analysis.
