Molecular mapping of Asian soybean rust resistance in soybean landraces PI 594767A, PI 587905 and PI 416764
(Wiley, 2015-02)Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is one of the most serious diseases of soybean. The soybean landraces PI 594767A, PI 587905 and PI 416764 previously showed high levels of resistance to a wide ... -
Multi-Level approach for the analysis of water effects in corn flakes
(American Chemical Society, 2008-08)The purpose of this work was to analyze the effect of water on thermal transitions, mechanical properties, and molecular mobility in corn flakes (CF), and their relationships. Commercial common (CCF) and sugar-frosted (SCF) ... -
Multi-parent QTL mapping reveals stable QTL conferring resistance to Gibberella ear rot in maize
(Springer, 2020-12)Maize production is on risk by Gibberella ear rot (GER) caused by Fusarium graminearum. This is one of the most important ear rot diseases in temperate zones as it leads to yield losses and production of harmful mycotoxins. ... -
Multi-parental QTL mapping of resistance to white spot of maize (Zea mays) in southern Brazil and relationship to QTLs of other foliar diseases
(Wiley, 2021-10)Maize white spot (MWS) is one of the most important foliar diseases in Brazil causing significant yield losses. Breeding genotypes with MWS resistance is the most sustainable alternative for managing such losses; however, ... -
El nabo como recurso forrajero invernal en la producción de carne
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-08)El objetivo del trabajo fue evaluar la producción de carne con nabo forrajero (Brassica napus x B. oleracea cv Interval) en cultivo puro y en mezcla con avena bajo pastoreo con novillitos a fines del invierno. El experimento ... -
Nitrogen fertilization effects on forage production and nutritive value of 4 tropical grasses on alkaline soils in Argentina
(International Center for Tropical Agriculture (CIAT), 2023-09)This study evaluated effects of nitrogen (N) fertilization and gypsum application and their interactions on total pasture forage production and nutritive values of Chloris gayana cultivars ‘Santana’ and ‘Finecut’ and Panicum ... -
Nutritional evaluation of dried tomato seeds
(Oxford Academic Press, 2003-01)Two samples of tomato seeds, a by-product of the tomato canning industry were evaluated to determine proximate analysis, amino acid content, and digestibility, TMEn, and protein efficiency ratio. Tomato seeds were also ... -
On-farm soybean genetic progress and yield stability during the early 21st century: A case study of a commercial breeding program in Argentina and Brazil
(Elsevier, 2024-03)CONTEXT: Most studies assessing the genetic progress in soybean have traditionally focused on retrospectives approaches, where commercial genotypes released over an extended period are tested in a limited number of ... -
Organic agriculture in Argentina’s Pampas. A case study on Pampa Orgánica Norte farmers
(Cambridge University Press, 2022-02)Faced with a society that demands the reduction of negative environmental impacts of agriculture while producing high-value, healthy food for local and export markets, Argentina is currently in a debate on the alternative ... -
Ornamentos sexuales y caracteres productivos en gallinas Campero Casilda
(Facultad de Ciencias Veterinarias, Universidad Nacional del Nordeste (UNNE), 2022-12)Con el objetivo de asociar el tamaño de los ornamentos sexuales con caracteres reproductivos y productivos en gallinas del cruzamiento de tres vías Campero Casilda se calcularon, en 97 aves de 30 semanas, los índices de ... -
OSTRICH-CROPGRO multi-objective optimization methodology for calibration of the growing dynamics of a second-generation transgenic soybean tolerant to high temperatures and dry growing conditions
(Elsevier, 2023-02)Current estimates show that the impact of climate change on agriculture will result in yield losses in major crops of 8–43%, mainly due to a combination of drought and heat. Second-generation transgenic crops are expected ... -
Overcoming seed dormancy of junglerice (Echinochloa colona)
(Universidad de Concepción (Chile), 2022-08)Junglerice (Echinochloa colona L. Link) seed dormancy can persist 8 months after harvest and, once overcome, seeds can germinate over a long period of time. Light or high temperatures could overcome seed dormancy, while ... -
Pathogenic diversity of soybean rust in Argentina, Brazil, and Paraguay
(Springer, 2013-01)Phakopsora pachyrhizi, the cause of soybean rust, is an economically important pathogen of soybean in South America. Understanding the pathogenicity of indigenous fungal populations is useful for identifying resistant plant ... -
