• Multi temporal multispectral UAV remote sensing allows for yield assessment across European wheat varieties already before flowering (2024) · Frontiers in Plant Science · cited 46× · doi

  High throughput field phenotyping techniques employing multispectral cameras allow extracting a variety of variables and features to predict yield and yield related traits, but little is known about which types of multispectral features are optimal to forecast yield potential in the early growth phase.

• Performance of Spring Wheat Genotypes for Quality, Yield, and Related Reproductive Traits under Different Production Systems (2026) · Advances in Biology & Earth Sciences · doi

  The study identifies a gap in understanding the impact of genotype-by-production system interactions on reproductive parameters, yield components, and grain quality traits. Prior work has focused on genotype × environment or genotype × management interactions, but the study clarifies explicitly the impact of varying input intensities on both yield and quality indicators.

• Multi temporal multispectral UAV remote sensing allows for yield assessment across European wheat varieties already before flowering (2024) · Frontiers in Plant Science · cited 46× · doi

  Traditional methods for phenotyping of yield and yield related traits often require manual labor and are thus slow, expensive and subjective. Assessing grain yield directly remains infeasible under field conditions. The study only involved 19 and 18 European wheat varieties, respectively. The study was conducted over two years, which may not be sufficient to capture long-term trends. The study used a specific type of multispectral camera and UAV, which may not be representative of all possible configurations.

• Cause and effect analysis for yield and grain quality traits in rice (Oryza sativa L.) (2026) · Electronic Journal of Plant Breeding · doi

  The current selection approach based on grain yield is misleading. There is a need to understand the association between yield and its causative characters. The relationship between yield and grain quality traits is not well understood.
