Genomic selection refers to the use of genotypic information for predicting breeding values of selection candidates. A prediction formula is calibrated with the genotypes and phenotypes of reference individuals constituting the calibration set. The size and the composition of this set are essential parameters affecting the prediction reliabilities. The(More)
In sexually reproducing organisms, meiotic crossovers ensure the proper segregation of chromosomes and contribute to genetic diversity by shuffling allelic combinations. Such genetic reassortment is exploited in breeding to combine favorable alleles, and in genetic research to identify genetic factors underlying traits of interest via linkage or(More)
Maize kernels with diverse colors have pigments and other substances with antioxidant capacity that can be highly beneficial for human health. Our objectives were to analyze antioxidant capacity of the different maize kernel colors, to investigate if selection for color intensity increases antioxidant capacity and to check the effect of bakery processing on(More)
Ageing reduces vigour and viability in maize inbred lines due to non-heritable degenerative changes. Besides non-heritable genetic changes due to chromosome aberrations and damage in the DNA sequence, heritable changes during maize conservation have been reported. Genetic variability among aged seeds of inbred lines could be used for association studies(More)
A generalized way to obtain a maize (Zea mays L.) synthetic variety is to randomly mate all possible crosses among inbred lines, but, when the number of lines is large, it would save time and effort to use other mating methods. This work is aimed to determine the utility of two alternative methods, assuming that an equal contribution of each inbred line to(More)
Reciprocal recurrent selection (RRS) was proposed for simultaneously improving two populations and their cross. A modification of the classical full-sib RRS (FS-RRS) was proposed in which the performance of full-sibs and S2 families is combined in a selection index (FS-S2-RRS). The Mediterranean corn borer (MCB) is the main corn borer species in the(More)
A field study was carried out to analyze the short-term impacts of replacing mineral by organic fertilizers on the microbial and biochemical parameters relevant for soil fertility and crop yield. Three types of fertilization regimes were compared: (1) conventional fertilizer regime with inorganic fertilizer, and combined integrated fertilizer regimes in(More)
The pink stem borer (Sesamia nonagrioides Lefèvbre) is the most important pest of maize (Zea mays L.) throughout the Mediterranean area. The maize composite EPS12 has been chosen as the base population for a breeding program based on its resistance to pink stem borer, with the main selection criterion being resistance to stem tunneling. Yield was taken as a(More)
