Application of RAPD markers for genetic distance analysis of hybrid rice parental lines

Published on Jul 30, 2018 04:09 AM

The genetic similarities of 19 hybrid rice parental lines
were estimated using RAPD markers. Molecular genetic
distances derived from dice's similarity coefficients were
based on 133 RAPD markers. Cluster dendrograms were
generated for molecular genetic distances. Genetic
variability among .hermo-sensitive genetic male sterile
(TGMS) lines was ml.lch lower than that among cytoplasmic
genetic male sterile (CMS) lines. PCR analysis based on
10 RAPD primers detected sufficient polymorphisms for
the germplasm characterisation and genetic distance. The
cluster analysis based on these markers revealed close
genetic relationship among rice genotypes currently used
in the hybrid rice breeding programmes.
