Genetic distance and hybrid value in tropical maize under P stress and non stress conditions in acid soils
An emphasis in maize breeding for areas with acid soils is the development of varieties with tolerance to P-deficiency plus high yield potential in acidic as well as normal soils. This study was carried out to assess the ...
Use of SSRs for establishing heterotic groups in subtropical maize
Heterotic groups and patterns are of fundamental importance in hybrid breeding. The objectives of our research were to: (1) investigate the relationship of simple sequence repeats (SSR) based genetic distances between ...
Construction of a SSR linkage map and mapping of quantitative trait loci (QTL) for leaf angle and leaf orientation with an elite maize hybrid
Maize (Zea mays L.) breeders have begun selecting for more compact plants for higher density planting in order to increase yield per unit area. Leaf angle and leaf orientation are very important traits affecting maize plant ...
High-throughput SNP genotyping with the GoldenGate assay in maize
Single nucleotide polymorphisms (SNPs) are abundant and evenly distributed, and they have become an ideal marker system for genetic research in many organisms. Several high throughput platforms have been developed that ...
Comparison of the performance of synthetic maize varieties created based on either genetic distance or general combining ability of the parents
(Consiglio per la ricerca in agricoltura e l'analisi dell'economia agraria, Forestry Reaserch Centre; tituto Sperimentale per la Cerealicoltura, 2012)
Synthetics varieties are grown by farmers and used by breeders to select new inbred lines. In countries unable to market hybrids, use of synthetics leads to yield improvements over landraces. Synthetics are derived from ...
