Three computationally efficient algorithms of GP including RHBK, RHDK, and RHPK were developed in approximate genome-based kernel model. The drastically growing amount of genomic information contributes to increasing computational burden of genomic prediction (GP). In this study, we developed three computationally efficient algorithms of GP including RHBK, RHDK, and RHPK in approximate genome-based kernel model, which reduces dimension of genomic data via Nyström approximation and decreases the computational cost significantly thereby. According to the simulation study and real datasets, our three methods demonstrated predictive accuracy similar to or better than RHAPY, GBLUP, and rrBLUP in most cases. They also demonstrated a substantial reduction in computational time compared to GBLUP and rrBLUP in simulation. Due to their advanced computing efficiency, our three methods can be used in a wide range of application scenarios in the future.

Theoretical and Applied Genetics

THEORETICAL AND APPLIED GENETICS 在现代植物遗传学、植物基因组学和植物生物技术的所有关键领域发表原创研究和评论文章。所有工作都需要有明确的遗传成分并对植物育种产生重大影响。只有结合新的实验数据和/或如果它们表明在植物遗传学或育种中的相关应用，理论考虑才被接受。该杂志强调实用性，侧重于对主要作物植物的研究和介绍创新方法的文章。

The journal "Theoretical And Applied Genetics" publishes original research and review articles in all key areas of modern plant genetics, plant genomics, and plant biotechnology. All work must have a clear genetic component and make a significant impact on plant breeding. Theoretical considerations are only accepted when combined with new experimental data and/or when they demonstrate relevant applications in plant genetics or breeding. The journal emphasizes practicality, focusing on research on major crop plants and articles introducing innovative methods.
