    • Classification of argentine maize landraces in heterotic groups 

      Delucchi, Carla; Eyherabide, Guillermo; Lorea, Roberto Daniel; Presello, Daniel Alberto; Otegui, María Elena; López, César G. (Consiglio per la Ricerca in Agricoltura e l'Analisi dell'Economia Agraria, 2012)
      The genetic diversity of maize (Zea mays L) is a valuable and strategic natural resource that plays a key role in the breeding progress. However, exploitation of genetic variability from landraces has not reached a significant ...
    • Comportamiento de cultivares de maíz 2017/2018 parte I: Pergamino y San Antonio de Areco 

      Presello, Daniel Alberto; Lorea, Roberto Daniel; Eyherabide, Guillermo; Fernández, Mariana (2018-08)
      La elección de la semilla para el cultivo de maíz se realiza en base a parámetros de productividad, factores defensivos, de calidad y de precio/rentabilidad. En INTA Pergamino anualmente se evalúan los cultivares recomendados ...
    • Ecophysiological traits in maize hybrids and their parental inbred lines: Phenotyping of responses to contrasting nitrogen supply levels 

      D'Andrea, Karina Elizabeth; Otegui, María Elena; Cirilo, Alfredo Gabriel; Eyherabide, Guillermo (Elsevier, 2009-10)
      Maize (Zea mays L.) breeding based primarily on final grain yield has been successful in improving this trait since the introduction of hybrids. Contrarily, understanding of the variation in ecophysiological processes ...
    • Edición génica: una oportunidad para la región 

      Feingold, Sergio Enrique; Bonnecarrére, Victoria; Nepomuceno, Alexandre; Hinrichsen, Patricio; Cardozo Tellez, Lourdes Maria; Molinari, Hugo; Barba, Paola; Eyherabide, Guillermo; Ceretta, Sergio Eduardo; Dujack, Christian (Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2018-12)
      Especialistas de los INIAs que integran el PROCISUR alientan el debate en torno a la ingeniería genética, a partir de los avances que se están alcanzando con la edición génica. Analizan el potencial de las tecnologías de ...
    • Gene action controlling stability and adaptability in maize 

      Eyherabide, Guillermo; Boca, Rosa Teresa; Lopez, César (2016)
      Limited knowledge about the genetic merit of maize landraces contributes to their little use in breeding, al-though some reports pointed them as a source of useful alleles. Repeated cultivation of landraces ...
    • Genetic diversity and linkage disequilibrium in the Argentine public maize inbred line collection 

      Olmos, Sofía Eugenia; Lía, Verónica Viviana; Eyherabide, Guillermo (2017)
      Knowledge of linkage disequilibrium (LD) patterns is considered a prerequisite for effective association mapping studies. However, no LD analysis in the Argentine public temperate maize collection has been reported to date. ...
    • Genetic diversity near the DGAT1-2 gene for high oleic acid content and kernel trait variation in a maize breeding collection 

      Olmos, Sofía Eugenia; Trejo, J.M.; Percibaldi, Nora Mabel; Eyherabide, Guillermo (2018-08)
      Previous studies in maize have identified three quantitative trait loci (QTLs) coding for high oleic acid content (HOAC) (QTLs oleic6-1, oleic6-2, and oleic6-3) at bins 6.04–6.05, proximal to the DGAT1-2 gene. The aims of ...
    • Genetic relatedness and population structure within the public Argentinean collection of maize inbred lines 

      Olmos, Sofí­a Eugenia; Delucchi, Carla; Ravera, Melina Andrea; Negri, Maria Emilia; Mandolino, Cecilia Ines; Eyherabide, Guillermo (2014)
      Genetic diversity of an Argentinean public temperate inbred maize collection has not been previously assessed. This collection includes mainly locally developed orange flint germplasm and a group of temperate inbred lines ...
    • Genetic variability within accessions of the B73 maize inbred line 

      Olmos, Sofí­a Eugenia; Lorea, Roberto Daniel; Eyherabide, Guillermo (2014)
      The maize inbred line B73 has been extensively studied at the molecular level. Researchers now have access to the genome sequence of B73 as well as to databases of biallelic and multiallelic markers where functional ...
