Abstract

The BSG test was used in an investigation of the linear differentiation in rye variety 'Zhitkinskaya', common wheat variety 'Aurora' and two secondary Triticale namely AD-196 and F-1239.Chromosomes of 'Aurora' variety and wheat chromosomes within Triticale may be easily divided into "constant" and 'variable' chromosomes as described previously (lordansky et al. 1977; Zurabishvili et al 1977).It is necessary to emphasize that the diversity of "variable" chromosomes underlies karyotypical polymorphism within wheat and Triticale species. The polymorphism observed exists in parallel with strict homomorphism of homologous chromosomes.In IB chromosomes of 'Aurora' variety, the short arm is substituted by the rye chromosome arm. The karyotype of Triticale AD-196 consists of six pairs of rye chromosomes and fifteen pairs of wheat chromosomes.

摘要

BSG 试验被用于研究黑麦品种“Zhitkinskaya”、普通小麦品种“奥罗拉”和两个次生triticale，即 AD-196 和 F-1239 的线性分化。“奥罗拉”品种的染色体和 triticale 内的小麦染色体可以像以前描述的那样很容易地分为“恒定”和“可变”染色体（lordansky 等人，1977 年；Zurabishvili 等人，1977 年）。需要强调的是，“可变”染色体的多样性是小麦和 triticale 种内核型多态性的基础。观察到的多态性与同源染色体的严格同形存在是平行的。在“奥罗拉”品种的 IB 染色体中，短臂被黑麦染色体臂取代。Triticale AD-196 的核型由六对黑麦染色体和十五对小麦染色体组成。
