TL;DR: The lack of relationship between the traits, in magnitude as well as significance, indicates that these characters are controlled by different gene groups, and simultaneous selection for both nutrient use efficiency and tolerance to nutritional stress is possible, if the mechanisms that confer efficiency andolerance are not competitive.

TL;DR: It was concluded that SynD and SynF testers are adequate to identify inbreed lines with high GCA effects, and it's possible to identify new lines withhigh heterotic potential in each one of the four testers.

TL;DR: In this article, the relationship between root morphology and nutrient use efficiencies for both nutrients was investigated in maize inbred lines and the shoot and root morphology traits were associated with the acquisition efficiency of both N and P in all of the environments that were evaluated.

TL;DR: The higher allelic frequency variation within each tropical heterotic pool and the high genetic diversity between the inbreds were evidence of heterotic groups within the main Tropical heterotic pools.

TL;DR: To improve the accuracy of selection for NUE, a selection index involving the total root length, daily growth and NUpE traits under both N levels is recommended, as these traits had high correlations with and direct effects on NUE.
