Key messages The use of a competition model in the analysis of yield data from single-row hybrid maize METs improves the accuracy of genotype selection and thus the rate of genetic gain, while it ensures resource use efficiency in resource-constrained breeding programs. Abstract Conducting large-scale multi-environment trials (METs) is practically challenging to breeding programs in Sub-Saharan Africa due to limitations of lan...

Key message Leaf width was correlated with plant-level transpiration efficiency and associated with 19 QTL in sorghum, suggesting it could be a surrogate for transpiration efficiency in large breeding program. Abstract Enhancing plant transpiration efficiency (TE) by reducing transpiration without compromising photosynthesis and yield is a desirable selection target in crop improvement programs. While narrow individual leaf wi...
