In: Journal of Agricultural Research Kafrelsheikh Univeristy 2010.v.36(4)Summary: Stigma characteristics are important traits, which contribute to the efficient improvement of commercial seed production in hybrid rice. Two cytoplasmic male sterile (eMS) lines of rice from different male sterility sources were evaluated for stigma characters and other various floral traits. Spikelet and stigma traits were recorded in the CMS lines, Fl hybrids, and F2 population ofthe crosses. Considerable variations existed between CMS lines for these traits. Molecular marker analysis was screened to identifY a specific DNA marker linked to stigma characters. Results identified one DNA marker named T86, which was associated with stigma traits.
