| 摘 要： | 以四倍体的半矮秆小麦地方品种矮兰麦(Trilicum turgidum L., 2n=28,AABB)作母本与采自河南的抗穗发芽节节麦(Aegilops tauschii Cosson,2n=14,DD)杂交。杂种F_1植株经0.05％秋水仙碱处理后获得矮兰麦一节节麦双二倍体(2n=42,AABBDD)。本文报道了该双二倍体的形态、主要农艺特点、减数分裂等,并讨论了在育种上的利用问题。

| Abstract: | An amphidiploid between tetraploid landrace Ailanmai (Trilicum turgidum L.) which is from Sichuan, China, and Aegilops tauschii Cosson, native to Henan, China was obtained by means of 0.05%colchicine treatment of the F_1 hybrids of Ailanmai×Ae. tauschii. The present paper reported preliminary studies of the amphidiploid on its morphology, cytology and agronomic characters. The result shows the dwarf gene of Ailanmai and pre-harvest sprouting gene of male parent are expressed in this amphidiploid. However, this amphidiploid is a material good for studies of the origin of the oriental common wheat. |
