标题： Interactive Hybrid Rice Breeding with Parametric Dual Projection

摘要： 杂交水稻育种通过将不同的水稻品系进行杂交，并在田间培育产生的杂种，以选择具有理想农艺性状的品种，例如更高的产量。 最近，基因组选择作为一种高效的杂交水稻育种方法出现了。 它基于基因预测杂种的性状，有助于排除许多不理想的杂种，大大减少了田间栽培的工作量。 然而，由于基因组预测模型的准确性有限，育种者仍需结合自己的经验与模型来识别控制性状的调控基因并选择杂种，这一过程仍然耗时。 为了简化这一过程，本文提出了一种可视化分析方法，以促进交互式杂交水稻育种。 调控基因的识别和杂种的选择自然构成了一个双分析任务。 因此，我们开发了一种具有理论保证的参数化双投影方法，以促进交互式的双分析。 基于这种双投影方法，我们进一步开发了基因可视化和杂种可视化，以验证所识别的调控基因和杂种。 我们的方法的有效性通过参数化双投影方法的定量评估、案例研究中所识别的调控基因和理想杂种以及育种者的积极反馈得到了证明。 显示英文摘要

摘要： Hybrid rice breeding crossbreeds different rice lines and cultivates the resulting hybrids in fields to select those with desirable agronomic traits, such as higher yields. Recently, genomic selection has emerged as an efficient way for hybrid rice breeding. It predicts the traits of hybrids based on their genes, which helps exclude many undesired hybrids, largely reducing the workload of field cultivation. However, due to the limited accuracy of genomic prediction models, breeders still need to combine their experience with the models to identify regulatory genes that control traits and select hybrids, which remains a time-consuming process. To ease this process, in this paper, we proposed a visual analysis method to facilitate interactive hybrid rice breeding. Regulatory gene identification and hybrid selection naturally ensemble a dual-analysis task. Therefore, we developed a parametric dual projection method with theoretical guarantees to facilitate interactive dual analysis. Based on this dual projection method, we further developed a gene visualization and a hybrid visualization to verify the identified regulatory genes and hybrids. The effectiveness of our method is demonstrated through the quantitative evaluation of the parametric dual projection method, identified regulatory genes and desired hybrids in the case study, and positive feedback from breeders.
