Sixteen rice genotypes including 3 cytoplasmic male sterile (CMS) lines, 5 restorer lines an...

The genotypes of hybrid rice with their parental lines were analyzed using microsatellite markers and some non-parental bands were observed in hybrid (heterozygous) individuals. These nonparental bands could be due to formation of heteroduplex DNA between allelic sequences. To test this hypothesis two source of DNA material were used. Firstly DNA t...
