Fertility restorer (Rf) gene linked STMS marker: An efficient tool for testing the genetic purity of hybrid rice (Oryza sativa L.) seed

Published on

A fertility restorer (Rf) gene linked STMS marker, RM 6100
as well as Grow Out Test (GOT) were used for testing the
genetic purity of hybrid seed of eight popular rice hybrids.
The genetic purity ranging from 96.00% to 100.00%, could
be determined through marker, whereas, it varied from
97.00% to 99.50% in GOT. The comparative assessment of
both methods exhibited that molecular marker was more
efficient than GOT, as it could detect 0.25-2.50% more
impurities very precisely as compared to GOT.It suggests
that a single Rf gene linked co-dominant STMS marker
appeared to be a simple, precise and quick option over
GOT for testing the purity of hybrid seed lots in short span
of time.
