Changes of starch composition by postflowering environmental conditions in kernels of maize hybrids with different endosperm hardness
Martinez, Roberto Dionisio; Cirilo, Alfredo Gabriel; Cerrudo, Anibal Alejandro; Andrade, Fernando Héctor; Reinoso, Luis; Valentinuz, Oscar Rodolfo; Balbi, C.N.; Izquierdo, Natalia Gabriela (2017-05)Starch composition of maize grains is of great importance when used in animal feed and many processing industries. Maize production involves hybrids with different kernel composition and hardness, sown at areas that range ... -
Composition and thermal properties of starch in flint maize (Zea mays, L.) kernels: location and crop management effects
Actis, Marcos; Farroni, Abel Eduardo; Andrade, Fernando Hector; Valentinuz, Oscar Rodolfo; Cirilo, Alfredo Gabriel (Gerencia de Comunicación e Imagen Institucional, DG-SICyP, INTA, 2020-04)Flint maize kernels are processed by the dry-milling industry to produce the flaking grits used thereafter in the corn flakes industry. Flaking-grit yield during milling depends on kernel hardness whereas corn flakes ... -
Crop management affects dry-milling quality of flint maize kernels
Cirilo, Alfredo Gabriel; Actis, Marcos; Andrade, Fernando Hector; Valentinuz, Oscar Rodolfo (Elsevier, 2011-05)Dry-milling performance of maize (Zea mays, L.) kernels primarily depends on their hardness. The flint type is harder than the dent and semi-dent maize, yielding a higher proportion of big endosperm pieces in the mill. ... -
Discriminating post-silking environmental effects on starch composition in maize kernels
Martínez, Roberto D.; Cirilo, Alfredo Gabriel; Cerrudo, Aníbal Alejandro; Andrade, Fernando Hector; Izquierdo, Natalia Gabriela (Elsevier, 2019-05)Maize (Zea mays L.) endosperms with high amylose proportion are harder and denser than endosperms with low amylose. Environmental conditions could affect amylose/starch ratio. The purpose of this work was to prove the ... -
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 ... -
Environment affects starch composition and kernel hardness in temperate maize
Martínez, Roberto Dionisio; Cirilo, Alfredo Gabriel; Cerrudo, Aníbal Alejandro; Andrade, Fernando Hector; Izquierdo, Natalia Gabriela (Wiley, 2022-03)BACKGROUND: Protein percentage and kernel weight affect the endosperm hardness of maize grains. However, changes in starch composition could also modify kernel hardness, which is often predicted through milling ratio. The ... -
Environment, management, and genetic contributions to maize kernel hardness and grain yield
Cerrudo, Aníbal Alejandro; Martinez, Dionisio Roberto; Izquierdo, Natalia Gabriela; Cirilo, Alfredo Gabriel; Laserna, Paula; Reinoso, Lucio; Valentinuz, Oscar Rodolfo; Balbi, Celsa; Andrade, Fernando Hector (2017-09)Dry milling performance of maize (Zea mays L.) is directly related to kernel hardness. This study assessed the contribution of maize hybrid and crop growing condition on kernel hardness and grain yield. Three hybrids that ... -
Genetic gains in grain yield and related physiological attributes in Argentine maize hybrids
Luque, Sergio F.; Cirilo, Alfredo Gabriel; Otegui, María Elena (Elsevier, 2006-02)Genetic gains in grain yield and related phenotypic attributes have been extensively documented in maize (Zea mays L.), but the effect of breeding on the physiological determinants of grain yield is yet poorly understood. ... -
Kernel number and kernel weight determination in dent and popcorn maize
Severini, Alan David; Borrás, Lucas; Westgate, Mark E.; Cirilo, Alfredo Gabriel (Elsevier, 2011-02)Yield formation in maize (Zea mays L.) dent hybrids has been directly linked to the rate of plant biomass accumulation and partitioning of assimilates to the developing grain. Maize popcorn genotypes have been studied less ... -
Kernel weight in maize: genetic control of its physiological and compositional determinants in a dent × flint-caribbean RIL population
Mandolino, Cecilia Ines; D´Andrea, Karina Elizabeth; Piedra, Carlina V.; Alvarez Prado, Santiago; Olmos, Sofía Eugenia; Cirilo, Alfredo Gabriel; Otegui, María Elena (Maydica-ist Sper Cerealicoltur, 2016-12)The genetic control of maize kernel weight (KW) determination could be studied through its physiological and/ or compositional determinants. Our objective was to dissect the genetic control of maize KW by analyzing its ... -
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 ... -
Phenotypic plasticity for biomass partitioning in maize : genotype effects across a range of environments
Galizia, Luciana Ayelen; Munaro, Eugenia M.; Cirilo, Alfredo Gabriel; Otegui, María Elena; D’Andrea, Karina E. (Elsevier, 2020-10)El rendimiento en grano de maíz está determinado por el genotipo (G), el ambiente (E) y los efectos de la interacción G × E que influyen en la expresión de los rasgos a lo largo del ciclo del cultivo. Líneas endocriadas e ...
