摘要：

<正> An artificial amphiploid RSP (2n = 42, AABBDD) between tetraploid landrace Ailanmai (Triticum turgidum L., 2n= 28, AABB) and Aegllops tauschii (DD, 2n = 14) expressed high tolerance to preharvest sprouting which derived from Ae. tauschii. Tolerance to preharvest sprouting of RSP was examined by four ways in six varying periods after anthesis. The germination percentages of preharvest intact spikes were only 6.06% in its high peak period of germination. Its tolerance was mainly decided by the seed dormancy. It was showed that the tolerance to sprouting in ' RSP' derived from Ae. tauschii was inherited as a recessive trait which was controlled by one gene, located on chromosome 2D.
