Rice crop in cyclone prone coastal areas is most frequently subjected to lodging at reproductive stage causing severe yield loss. Breeding for non-lodging rice varieties is herculean task as it is controlled by structural properties of the culm and weather parameters. Present study aimed to select lodging resistant lines using phenotypic characters and molecular markers in early generations. Co-segregation banding pattern for lodging resistant families with either homozygous donor allele or heterozygous allele for markers RM 20557, RM 5509 among the F3 families of MTU 7029/II 110-9-1-1-1-1 and for markers RM 6933 and RM 216 in case of F3 families pertaining to MTU 7029/MTU1121 indicates that these markers can be useful in selection of lodging resistant lines in early generations. Correlation studies revealed that positive correlation of culm diameter with panicle length was observed among the F3 families of MTU 7029/II 110-9-1-1-1-1 and negative correlation of bending strength with number of ear bearing tillers per plant in case of MTU 7029/MTU 1121 indicates specific contribution of alleles for lodging resistance depends on donors used.
