Abstract

The C-banding pattern of nine meiotic chromosomes of common wheat (Triticum aestivum L.) as described. In F1s of crosses between monosomics of 'Chinese Spring' and two Spanish wheat cultivars, univalent chromosomes were used to aid the recognition and analysis of the C-banding pattern for the individual chromosomes. The identification of one chromosome involved in one translocation in 'Chinese Spring' x 'Pané 247' has been made through heterochromatin bands observed in the chromosomes involved in multivalents.

摘要

文中描述了普通小麦(Triticum aestivum L.)九个减数分裂染色体的 C-带模式。在“中国春”单体系与两个西班牙小麦品种杂交的 F1 中,单价体染色体被用来帮助识别和分析各个染色体的 C-带模式。通过观察多价体中涉及的染色体上的异染色质带,确定了“中国春”x“Pané 247”中涉及的一个易位的一条染色体。
