Abstract

Potato market value is heavily affected by tuber quality traits such as shape, color, and skinning. Despite this, potato breeders often rely on subjective scales that fail to precisely define phenotypes. Individual human evaluators and the environments in which ratings are taken can bias visual quality ratings. Collecting quality trait data using machine vision allows for precise measurements that will remain reliable between evaluators and breeding programs. Here we present TubAR (Tuber Analysis in R), an image analysis program designed to collect data for multiple tuber quality traits at low cost to breeders. To assess the efficacy of TubAR in comparison to visual scales, red-skinned potatoes were evaluated using both methods. Broad sense heritability was consistently higher for skinning, roundness, and length to width ratio using TubAR. TubAR collects essential data on fresh market potato breeding populations while maintaining efficiency by measuring multiple traits through one phenotyping protocol.

TubAR:一个从图像中量化块茎形状和皮肤特征的R包
马铃薯的市场价值在很大程度上受到块茎形状、颜色和去皮等品质特征的影响。尽管如此,马铃薯育种家往往依赖主观量表,无法准确定义表型。个人评估人员和进行评级的环境可能会对视觉质量评级产生偏见。使用机器视觉收集质量性状数据可以实现精确的测量,这将在评估人员和育种计划之间保持可靠。在这里,我们介绍了TubAR(R中的块茎分析),这是一个图像分析程序,旨在以较低的成本收集多种块茎质量性状的数据。为了评估TubAR与视觉量表的疗效,使用这两种方法对红皮土豆进行了评估。使用TubAR,剥皮、圆度和长宽比的广义遗传力始终较高。TubAR收集新鲜市场马铃薯育种种群的基本数据,同时通过一个表型方案测量多个性状来保持效率。
