Abstract

Hybrids were produced from crossing Hordeum vulgare, H. bogdanii, Agropyron caninum and × Triticosecale onto H. parodii (6x or 4x). The rates at which hybrids were produced, expressed in terms of plantlet establishment as percent pollinated florets, ranged from 0.47%, (6x H.parodii × 6x × Triticosecale cv. 'Welsh') to 6.3% (4x H. parodii × 2x H. vulgare cv. Betzes). Based on frequencies of paired configurations at MI, autosyndetic pairing appeared to be promoted by the presence of a Secale cereale genome but suppressed by the genome of H. vulgare.

摘要

杂种是通过将大麦、冰草、黑麦草和 × 中间偃麦草杂交到披碱草（6x 或 4x）中产生的。杂种的产生率，以授粉小花的植物芽建立百分比表示，范围从 0.47%（6x 披碱草 × 6x × 中间偃麦草 cv. 'Welsh'）到 6.3%（4x 披碱草 × 2x 大麦 cv. Betzes）。基于 MI 时配对构型的频率，自体合配对黑麦草基因组的存在似乎有促进作用，但对大麦基因组的存在有抑制作用。
