Diploid hybrids between Hordeum chilense and three other species, namely H. vulgare, H. bulbosum and Secale cereale, are described together with the amphidiploid of H. chilensexH. vulgare. Both the diploid hybrid and the amphidiploid of H. chilensexH. vulgare were chromosomally unstable, H. chilensexH. bulbosum was less so, while H. chilensexS. cereale was stable. Differential amphiplasty was found in all combinations. No homoeologous pairing was found in the Hordeum hybrids but in H. chilensexS. cereale there was chromosome pairing both within the two genomes and between the genomes.
描述了二倍体杂种,其亲本为 3 个种,即:Hordeum chilense、Hordeum vulgare、Hordeum bulbosum 和 Secale cereale,以及 Hordeum chilensexHordeum vulgare 的双二倍体杂种。Hordeum chilensexHordeum vulgare 的二倍体杂种和双二倍体杂种,染色体均不稳定,Hordeum chilensexHordeum bulbosum 的情况稍好,而 Hordeum chilensexSecale cereale 的则稳定。所有组合均存在差异的杂种形成。在这些大麦杂种中未发现同源配对,但在 Hordeum chilensexSecale cereale 中,两个基因组内和两个基因组之间都存在染色体配对。
