Supporting evidence — 7 representative gaps

• 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.

• Genetic variability, heritability and character association studies in sweet corn (Zea mays L. saccharata) (2026) · Electronic Journal of Plant Breeding · cited 4× · doi

  The study identifies challenges in improving sweet corn traits through breeding programs. One challenge is the environmental influence on traits, which can affect the accuracy of selection. Another challenge is the need to balance the improvement of multiple traits, such as yield and quality.

• Genetic dissection of grain yield and correlated proxy traits under suboptimal conditions (2026) · Theoretical and Applied Genetics · doi

  Further research is needed to explore the genetic basis of crop yield under suboptimal conditions - The use of proxy traits for improving grain yield under stress conditions should be further investigated - Optimizing MAGIC genotyping and mapping strategies could be a direction for future research

• Multi-environment evaluation and stability analysis of early-maturing drought-tolerant tropical maize (Zea mays L.) hybrids using AMMI and GGE models (2026) · Frontiers in Plant Science · doi

  The study identifies the challenge of genotype x environment interaction in maize production. The study notes the difficulty of evaluating maize hybrids under different environmental conditions. The study highlights the need to identify stable and adaptable hybrids under moderate and severe stress conditions.

• Early Mass Selection Response of Two Quinoa Landraces under Highlands Conditions in Northern Chile (2020) · Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca Horticulture · cited 1× · doi

  Despite the importance of the crop, limited research work on breeding aspects has been undertaken, leading to lack of information on the understanding of levels of variability of genotypes for different traits and their interactions.

• Long-term trends in grain yield and main nutrient contents of three staple cereal crops in China (1980–2024) (2026) · Frontiers in Nutrition · doi

  Further research is needed to understand the drivers of long-term changes in grain nutrient composition. Studies should investigate the effects of genetic improvement, agricultural management, and environmental changes on grain nutrient concentrations. Research should focus on developing strategies to improve grain nutrient concentrations while maintaining high yields.

• 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.
