Ability of in situ canopy spectroscopy to differentiate genotype by environment interaction in wheat
Arias, Claudia; Montero Bulacio, Enrique; Rigalli, Nicolás; Romagnoli, Martín; Curin, Facundo; Gonzalez, Fernanda Gabriela; Otegui, María Elena; Portapila, Margarita (Taylor & Francis, 2021-03)In recent years, the application of remote sensing techniques is gaining a growing interest and importance in agriculture. Researchers often combine data from near-infrared and red spectral bands according to their specific ... -
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 ... -
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 ... -
Water and radiation use efficiencies in maize: breeding effects on single-cross Argentine hybrids released between 1980 and 2012
Curin, Facundo; Severini, Alan David; Gonzalez, Fernanda Gabriela; Otegui, María Elena (Elsevier, 2019-11)Water deficit has been signaled as an important determinant of grain yield (GY) gaps between potential and actual GYs. Breeding for improved water as well as solar radiation productivities is a sustainable means to reduce ... -
Wheat yield progress and stability during the last five decades in Argentina
Curin, Facundo; Otegui, María Elena; Gonzalez, Fernanda Gabriela (Elsevier, 2021-07)Improvement of grain yield (GY) at farm level, which is closely related to GY potential, seems to be the main alternative to increase wheat (Triticum aestivum L) production. The aim of current research was to assess the ...
