摘要：

The intergeneric amphiploid Hordeum chilense x Aegilops squarrosa has been synthesized. The amphiploid plants have the expected chromosome number of 28. The average meiotic chromosome pairing was 12.48 bivalents + 3.04 univalents. The morphology of the amphiploid resembles that of the Aegilops parent. Nucleoli from both H. chilense and A. squarrosa are expressed in the amphiploid. Neither chromosome instability nor homoeologous pairing was found. The amphiploid is fertile and vigorous.
