Senescence is a complex developmental process that regulated by multitude of environmental, genetic, and physiological factors. Optimizing the timing dynamics this has potential to significantly impact crop adaptation future climates for maintaining grain yield quality, particularly under terminal stress. Accurately capturing senescence isolating genetic variance component requires frequent assessment as well intense field testing. Here, we evaluated compared temporally dense drone-based RGB- multispectral image sequences purpose. Regular measurements were made throughout filling phase more than 600 winter wheat genotypes across three experiments in high-yielding environment temperate Europe. At plot level, RGB indices extracted, time series modelled using different parametric semi-parametric models. The capability these approaches track was based on estimated model parameters, with corresponding parameters derived from repeated visual scorings reference. This approach represents need remote-sensing proxies capture entire process, onset conclusion senescence, rate progression.

In the current quest for a more sustainable, environment-friendly agriculture, variety mixtures are often suggested as practical option to increase stability of food production systems. Their effects on yield have been extensively researched, yet clear conclusions remain elusive, notably in terms mechanistic processes and optimal combinations. Furthermore, case wheat, is not only component equation: grain quality crucial bread value chain, wheat its rarely investigated. To that end, we conducted multi-year, multi-site mixture experiment investigating role performance five traits linked quality, mechanisms underlying these effects. Eight varieties were grown pure stands 2-variety mixtures, following full diallel design. We considered responses yield, protein content, thousand kernel weight, hectoliter Zeleny sedimentation value. Results showed generally outperformed global 5 parameters. particularly noticed an showing potential improve crop quality. Moreover, highlighted important light interception increased benefits. A detailed investigation into individual performances led us some rules combinations: advise combining with similar heights phenologies but different tillering abilities potential. This study thus shows represent promising solution sustainably With recommendations, our results could benefit farmers also processors bakers, promote adoption mixtures.
