| 摘 要： | 利用长休眠节节麦(Ae.tauschii)与四川的四倍体小麦地方品种矮兰麦(T.turgidum)杂交并加倍合成的新的抗穗发芽普通小麦"RSP"与"绵阳11"D染色体组的单体系列杂交,对来源于节节麦的晚生育期基因进行定位分析,以期在利用其穗发芽抗性时,克服其生育期较晚的特性。结果表明:该节节麦的2D和5D染色体上均存在晚生育期基因,2D的作用较5D更强。

| Abstract: | An artificial amphiploid wheat 'RSP'(2n=42,AABBDD) between tetraploid landrace Ailanmai(Triticum turgidum L.,2n=28,AABB) and Aegilops tauschii(2n=14,DD) had the superior character with high tolerance to preharvest sprouting deriving from Ae.tauschii.To determine the genes controlling the heading and anthesis date which were located in the D genome in the amphiploid 'RSP',it was crossed with a set of 'Mianyang 11' monosomics(D genome).The results indicated that 2D and 5D chromosomes of Ae.tauschii possessed ... |
