The red rice variety HPR 2795 is susceptible to lodging due to tallness whereas, PB 3 is a basmati variety having semi dwarf gene sd1. The present study was undertaken to incorporate the semi-dwarfing gene into the red rice variety HPR 2795 with the aim to reduce lodging losses, and to transfer the red grain trait of HPR 2795 into a Basmati genetic background of PB 3. The marker assisted selection was performed on the 55 genotypes of F2 population derived from PB 3 X HPR 2795 using sd1 specific primers. The foreground selection revealed that 27 plants were homozygous for gene Sd1. These selected plants also carries red seed colour that can be further utilized for future breeding.
