Abstract

Two main elements of the mechanism of preventing the homoeologue synapsis were revealed using statistical analysis of the univalent behavior in meiotic anaphase I in the whole series of monosomic lines of wheat cultivar Milturum 553. One of the elements was found to be controlled by chromosomes 1B, 3B and 6A, and the latter being equally effective in both double and single doses.

摘要

利用对小麦品种米尔图鲁姆553的一系列单体品系减数分裂后期I单价体行为的统计分析，揭示了阻止同源染色体联会机制的两个主要因素。其中一个因素被发现受1B、3B和6A染色体控制，且后者在双倍剂量和单倍剂量下均同样有效。
