We propose a novel concept and tool kit for predictive phenotyping. The proposed technology measures respiration properties as functions of growth conditions to identify genotypes with higher plasticity via homeostasis and adaptive morphophysiology. Combining calorespirometry, oxygen isotope analysis and functional-marker-assisted selection ('CalOxy-FMAS') for genotype screening will enable predicting the genetic potential for stable plant growth performance. Application of this novel tool kit can help identify genotypes with controlled homeostasis in changing environments and optimized growth performance. Simultaneously, it will allow a better balance in breeding for high yields and quality characteristics. Applying 'CalOxy-FMAS' can efficiently narrow the pool of genotypes to be screened for final phenotyping in the field.
我们提出了一种用于预测表型分析的新颖概念和工具包。所提出的技术将呼吸特性作为生长条件的函数进行测量，以通过稳态和适应性形态生理学来识别具有更高可塑性的基因型。结合热呼吸测定法、氧同位素分析和功能标记辅助选择（“CalOxy-FMAS”）进行基因型筛选，将能够预测植物稳定生长性能的遗传潜力。应用这种新颖的工具包有助于识别在变化环境中具有可控稳态和优化生长性能的基因型。同时，它将有助于在高产和品质性状育种之间实现更好的平衡。应用“CalOxy-FMAS”可以有效地缩小用于田间最终表型分析的待筛选基因型库。
