Summary: | The development of black rice with a fluffier texture at Universitas Jenderal Soedirman, which began in 2004, was carried out by crossing local black rice with the Mentik Wangi variety. At present, six black rice advanced breeding lines are ready for multi-location yield trials. Meanwhile, developing molecular marker-based plant breeding methods can facilitate a more efficient selection process. An important stage in developing molecular markers is marker validation, which aims to test the effectiveness in determining phenotypes in various genotypic and in new populations that differ from others based on the link between the marker and the expected character identified. This research aimed to determine molecular markers that can differentiate the level of amylose content in populations of F8 and F9 lines. The research was carried out on 10 (ten) genotypes consisting of the control variety Logawa, IRPM 112-19- 56, black rice, Mentik Wangi, and six lines. The amplification of the RM190, Wx and SSIIa markers showed polymorphic band. Based on the simple linear regression analysis, in F9, the SSIIa marker had the highest coefficient of determination compared to other markers. Hence, it had the greatest possibility of being a marker for selecting rice based on amylose content. |
