The genetic basis of commercial maize (Zea mays L.) is quite narrow. The incorporation of exotic germplasm, i.e. all germplasm that does not have immediate usefulness without selection for adaptation, is a way of enhancing the genetic basis of the material that a breeder can use. The populations of maize ‘Purdue Synthetic A o2’ (Purdue A) and ‘Purdue Synthetic B o2’ (Purdue B) were subjected to 18...
The objective of this study was to compare the selection of maize lines by genomic selection and phenotypic selection, performed on the basis of selection indices rather than on each trait separately. To achieve this, 256 plants of an F2 population (S1 lines) were genotyped with 177 microsatellite molecular markers. These lines were evaluated in experiments with replications, considering different...
Vitamin A Deficiency (VAD) is a major public health problem in Sub-Saharan Africa affecting 33 million preschool-age children. Enrichment of maize varieties with provitamin A could provide sustainable and affordable solution to VAD. This study was conducted to understand the extent of GEI effects on both grain yield and provitamin A content in 21 maize synthetics and identify synthetics combining...
