Stigma exsertion is important in increasing out crossing rate in rice hybrid parental lines. In the present investigation, inheritance pattern of stigma exsertion trait in F3 population developed between IR68897B x BF16B was studied. On phenotyping of 674 F3 plants, it segregated into 91 low, 456 moderate and 127 high stigma exsertion plants based on IRRI-SES scale published by INGER, 2014. Further, subjected to chi square analysis to test their goodness of fit to appropriate Mendelian ratios and showed significant. Thus, stigma exsertion is quantitative trait. Also transgressive segregation observed during phenotyping indicated that complementary gene action with additive effects and dispersed in both the parents. The frequency distribution showed continuous variation signifying that stigma exsertion trait is controlled by polygenes and influenced by environment.
