TL;DR: Results suggest that the combination of meta-analysis within a species of interest and synteny-based projections from a related model plant can be an efficient strategy for identifying new candidate genes for trait variation.

TL;DR: In this article, different criteria based on the diversity or on the prediction error variance (PEV) derived from the realized additive relationship matrix (RA-BLUP) were used to select the reference individuals.

TL;DR: A QTL detection performed on six connected F2 populations of 150 F2:3 families each, derived from four maize inbreds and evaluated for three traits of agronomic interest detected many epistatic interactions, particularly for grain yield QTL (R2 increase of 9.6%).

TL;DR: The study of the efficiency of marker-assisted selection based on an index combining the phenotypic value and the molecular score of individuals shows that the higher efficiency of MAS on QTLs with large effects in early generations is balanced by a higher rate of fixation of unfavourable alleles at QTLS with small effects in later generations, explaining why MAS may become less efficient than phenotyping selection in the long term.

TL;DR: The efficiency of marker-assisted selection based on an index incorporating both phenotypic and molecular information is evaluated with an analytical approach that takes into account the size of the experiment and may be a useful tool to optimize the experimental means for more complex genetic situations.
