Artificial selection for grain yield has increased net CO2 exchange of the ear leaf in maize crops
Cagnola, Juan I.; Parco, Martín; Rotili, Diego Hernán; Ploschuk, Edmundo L.; Curin, Facundo; Amas, Juan Ignacio; Luque, Sergio F.; Maddonni, Gustavo Angel; Otegui, María Elena; Casal, Jorge José (Oxford University Press, 2021-03)Identifying the physiological traits indirectly selected during the search for high-yielding maize hybrids is useful for guiding further improvements. To investigate such traits, in this study we focused on the critical ... -
Breeding effects on canopy light attenuation in maize: a retrospective and prospective analysis
Lacasa, Josefina; Ciampitti, Ignacio A.; Amas, Juan Ignacio; Curín, Facundo; Luque, Sergio F.; Otegui, María Elena (Oxford University Press, 2022-03)The light attenuation process within a plant canopy defines energy capture and vertical distribution of light and nitrogen (N). The vertical light distribution can be quantitatively described with the extinction coefficient ... -
Llenado y secado de granos de cuatro híbridos de maíz cultivados en fecha de siembra contrastantes en la zona núcleo maicera.
Amas, Juan Ignacio; Chazarreta, Yésica D.; Otegui, María Elena; Cirilo, Alfredo Gabriel (2017-09)La elección de la fecha de siembra del cultivo de maíz determina la duración y el momento de ocurrencia de las diferentes etapas de su ciclo ontogénico (4). El atraso de la siembra expone al llenado de granos a menor ... -
Maize breeding effects on grain yield genetic progress and its contribution to global yield gain in Argentina
Amas, Juan Ignacio; Curin, Facundo; D'Andrea, Karina Elizabeth; Luque, Sergio F.; Otegui, María Elena (Elsevier, 2024-08)Context or problem: Maize production in Argentina has increased in recent years, following the global gain (GG) in grain yield (GY). The GG in GY depends on genetic progress (GP), which requires frequent quantification to ... -
Maize genetic progress in the central Pampas of Argentina: effects of contrasting sowing dates
Amas, Juan Ignacio; Fernandez, Javier A.; Curin, Facundo; Cirilo, Alfredo Gabriel; Ciampitti, Ignacio A.; Otegui, María Elena (Elsevier, 2022-05)Delayed sowing date of maize (Zea mays L.) has become a broadly adopted practice in the Pampas region of Argentina, because late-sown crops frequently experience a more favorable water balance around flowering and a reduction ... -
Progreso genético en maíz en el Norte de Buenos Aires : efectos de fecha de siembra.
Amas, Juan Ignacio; Curín, Facundo; Otegui, María Elena; Cirilo, Alfredo Gabriel (2017-09)Los programas de mejoramiento genético de maíz templado en Argentina tienen como principal ambiente objetivo a la zona núcleo maicera (norte de la provincia de Buenos Aires y sur de la provincia de Santa Fe). En ella han ...
