Key message Simulations showed that hybrid performances issued from an incomplete
factorial between segregating families of two heterotic groups enable to calibrate genomic …

Abstract Background Sugarcane (Saccharum officinarum L.) is an economically important
crop with stalks as the harvest organs. Improvement in stalk quality is deemed a promising …

Abstract The Stiff Stalk heterotic pool is a foundation of US maize seed parent germplasm
and has been heavily utilized by both public and private maize breeders since its inception …

Although the use of heterosis in maize breeding has increased crop productivity, the genetic
causes underlying heterosis for nitrogen (N) use efficiency (NUE) have been insufficiently …

Key message We validated the efficiency of genomic predictions calibrated on sparse
factorial training sets to predict the next generation of hybrids and tested different strategies …

Key message Calibrating a genomic selection model on a sparse factorial design rather
than on tester designs is advantageous for some traits, and equivalent for others. Abstract In …

The objective of this work was to identify corn (Zea mays) genotypes with forage potential
and to evaluate the efficiency of testers to discriminate forage traits in topcrosses …

Maize yield components including row number, kernel number per row, kernel thickness,
kernel width, kernel length, 100-kernel weight, and volume weight affect grain yield directly …

The main topic of this thesis is the development of methodologies for QTL mapping in
multiparent populations (MPPs). QTL mapping or analysis is the attempt to discover the …
