摘要: 以旱稻基因型旱65为母本,稗草长芒稗为父本,通过杂交、回交技术,导入稗草高光效、速生快长基因,效果非常明显。

关键词: 旱稻, 长芒稗, 远缘杂交, 回交, 杂种优势

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
