Abstract

An 8 × 8 full diallel experiment based on 4 bunch plus 4 spreading types of groundnut (Arachis hypogaea L.) was conducted over three environments. For both number of pods and pod yield, additive, nonadditive and reciprocal cross effects were detected and these were also influenced by changes in environments. For number of pods additive genetic variance was predominant whereas it was approximately equal to non-additive genetic variance for pod yield. Graphical analysis revealed the presence of strong non-allelic interaction for number of pods whereas for pod yield absence of dominance and/or presence of non-allelic interaction was evident.

摘要

进行了三次试验，设计了 4 个品种系和 4 个扩展系的 8×8 完全双列杂交，对 4 个花生品种进行了研究。在荚果数和荚果产量方面，检测到了加性、非加性和互作效应，并且这些效应也受到环境变化的影响。在荚果数方面，加性遗传方差占主导地位，而在荚果产量方面，加性和非加性遗传方差大致相等。图形分析表明，荚果数存在强烈的非等位基因互作，而在荚果产量方面，没有显性和/或非等位基因互作的存在。
