摘要

在杂交组合中对芸苔(Brassica campestris L.)的硅质强度进行了定量遗传分析。火炬× DS-17-D采用北卡罗来纳实验II型设计。这表明存在高度的非加性遗传变异和高遗传力(广义)的所有测量的硅强度。这些结果与早期的研究结果一致，即少数控制唾液强度的基因可能在上位性上相互作用。关键词:硅橡胶强度，抗破碎性，遗传变异(加性和非加性)，遗传力。

Inheritance of siliqua strength in Brassica campestris L. II. Quantitative genetic analysis

Quantitative genetic analysis of siliqua strength in Brassica campestris L. was conducted in the cross cv. Torch × DS-17-D using the North Carolina experiment II design. This revealed the presence of a high degree of nonadditive genetic variance and a high heritability (broad sense) for all measures of siliqua strength. These results are in accordance with earlier findings of the likelihood of a small number of genes controlling siliqua strength which interact epistatically.Key words: siliqua strength, shatter resistance, genetic variances (additive and nonadditive), heritability.
