Construction and Analysis of a SRAP Molecular Genetic Map of japonica Rice (Oryza sativa L. sp.japonica)

A molecular genetic map of rice(Oryza sativa)was constructed with a 102 F_2 population from a cross of two rice cultivars‘Shennong 606’and‘Lijiangxintuanheigu’by using SRAP markers.The map con- sisted of 14 linkage groups,which include 129 genetic markers,and covers 1671.5 cM with an average genetic distance of 13.0 cM.A total of 17.2% distorted markers distributed in the map as Segregation Distortion Regions.
