Abstract: 7 years successive studies on the progenies derived from cross and backcross(BC)between uplandrice(O.sati va)genotype Han 65 and long-aw n barnyard grass(E.caudata)were carried out.The result sshowed that distant hy bridization was an effective w ay fo r transferring the gene(s)of higher grow th rate(HG R)and of higher photosy nthetic rate(HPR).

Key words: Upland rice, Long-aw n barnyard grass, Distant hybridization, Backcross, Heterosis
