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 ... -
Maize Nitrogen Use Efficiency: QTL Mapping in a U.S. Dent x Argentine-Caribbean Flint RILs population
Mandolino, Cecilia Ines; D'Andrea, Karina Elizabeth; Olmos, Sofía Eugenia; Otegui, María Elena; Eyherabide, Guillermo (2018-04)This study was aimed to identify quantitative trait loci (QTL) for nitrogen use efficiency (NUE) and related traits in a maize population derived from a cross between two lines with different genetic background (B100 and ... -
Source-sink relations and kernel weight in maize inbred lines and hybrids : responses to contrasting nitrogen supply levels
Hisse, Ignacio R.; D'Andrea, Karina Elizabeth; Otegui, María Elena (Elsevier, 2019-01)Maize (Zea mays, L.) kernel weight (KW) is regulated by the source-sink relationship at the early grain-filling period, when potential kernel size is defined, and at the effective grain-filling period, when final KW is ...
