Genetic interrelationships among medium to late maturing tropical maize inbred lines using selected SSR markers
Understanding the genetic relationships among breeding lines is fundamental in crop improvement programs. The objectives of this study were to apply selected polymorphic single sequence repeat (SSR) DNA markers and cluster ...
Detection of genetic integrity of conserved maize (Zea mays L.) germplasm in genebanks using SNP markers
Twenty maize landrace accessions regenerated and conserved in five maize genebanks were investigated for genetic integrity using 1,150 Single Nucleotide Polymorphisms (SNPs) and 235 SNP haplotypes. The genetic diversity ...
Near-Infrared Reflectance Spectroscopy (NIRS) for Protein, Tryptophan, and Lysine Evaluation in Quality Protein Maize (QPM) Breeding Programs
Quality protein maize (QPM) has approximately twice the tryptophan (Trp) and lysine (Lys) concentrations in protein compared to normal maize. Because several genetic systems control the protein quality of QPM, it is essential ...
QTLs asociados al contenido de carotenos en hojas de maiz (Zea mays L.)
Los carotenos son pigmentos antioxidantes que captan foto¬nes del espectro de luz visible y protegen a los tejidos de las plantas contra la foto-oxidación, lo cual está relacionado con la tasa fotosintética y rendimiento ...
Nucleotide diversity and molecular evolution of the PSY1 gene in Zea mays compared to some other grass species
Phytoene synthase (PSY), which is encoded by the phytoene synthase 1 (PSY1) gene, is the first rate-limiting enzyme in the plant carotenoid biosynthetic pathway. In order to examine the genetic diversity and evolution ...
Morpho-physiological traits associated with cold stress tolerance in tropical maize (Zea mays L.)
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Valorizzazione qualitativa dei cereali, 2010)
Winter season maize (Zea mays L.) has emerged a new crop in many parts of South and Southeast Asia, where the crop has to face low temperature regimes (<5°C) for few weeks during vegetative growth stage. The objective of ...
