A genetic approach to the species problem in wild potato
(Wiley, 2012-07)Wild potatoes are native to the Americas, where they present very wide geographical and ecological distribution. Most are diploid, obligate out‐crossers due to a multiallelic gametophytic self‐incompatibility (S) locus ... -
Amylose starch with no detectable branching developed through DNA-free CRISPR-Cas9 mediated mutagenesis of two starch branching enzymes in potato
(Nature Publishing Group, 2021-02-22)DNA-free genome editing was used to induce mutations in one or two branching enzyme genes (Sbe) in tetraploid potato to develop starch with an increased amylose ratio and elongated amylopectin chains. By using ribonucleoprotein ... -
Can agronomic phosphorus recommendations for potato be environmentally sustainable?
(IPNI, 2017)A better understanding of the relationship between the agronomic and environmental optimum for soil test P can guide potato growers in Buenos Aires province towards improved P fertilizer management. -
Canopy indices to quantify the economic optimum nitrogen rate in processing potato

Caracterización del estrés de nitrógeno en papa para industria usando el NDVI = Characterizing nitrogen stress in processing potato using NDVI
(Asociación Argentina de la Ciencia del Suelo, 2016)La medición de la reflectancia con sensores ópticos tiene el potencial de proporcionar información sobre el estatus de nitrógeno (N) durante el ciclo del cultivo de papa para industria y podría predecir la dosis de N. Los ... -
Chlorophyll meter for the evaluation of potato N status
(Springer, 2013-08)Here, we propose a new approach to determine the level of plant N nutrition, based on the relationship between chlorophyll meter (CM) readings and total biomass in potato plants. The objectives of this work were i) to ... -
Cold sweetening diversity in Andean potato germplasm from Argentina
(Wiley Online Library, 2018-04-02)BACKGROUND: Cold induced sweetening (CIS) is the accumulation of sucrose and reducing sugars in potato tubers at low temperatures. This process is central for the potato processing industry. During potato chip and French ... -
Comparative potato genome editing: Agrobacterium tumefaciens-mediated transformation and protoplasts transfection delivery of CRISPR/Cas9 components directed to StPPO2 gene
(Springer Netherlands, 2021-01-25)Delivery of the CRISPR/Cas9 components to the plant cells is a key step in its application as a genome editing tool. Here, we compared Agrobacterium-mediated transformation and protoplast transfection with CRISPR/Cas9 ... -
Conservación ex situ de variedades de papas nativas. Caso de estudio de la variedad ‘Collareja’ del noroeste de la Argentina
(Ediciones INTA, 2019-08)La papa andina nativa Solanum tuberosum Grupo Andigenum ha sido cultivada durante milenios en los Andes del noroeste de Argentina. Las variedades nativas de papa poseen una gran diversidad de formas y colores de sus ... -
Critical nitrogen dilution curve for processing potato in Argentinean Humid Pampas
(Springer, 2012-04)For processing potato, a new algorithm has been developed to determine nitrogen (N) requirement (NR) applying critical N dilution curve (Nc). The objectives of this work were i) to determine the Nc for processing potato ... -
Critical nitrogen dilution curve in processing potato cultivars
(Scientific Research, 2015-12)The critical nitrogen dilution curve (CNDC) can be used as a diagnostic tool to assess crop N nutrition during the growing season. Potato cultivars have different biomass production and accumulation of N and consequently ... -
Dosis óptima económica de fósforo en el cultivo de papa en el sudeste bonaerense
(2016-06)Asegurar una buena disponibilidad de fósforo (P) para el cultivo de papa, es tan importante como ajustar la estrategia de fertilización para producir el máximo rendimiento con la mayor eficiencia económica. El Avail, aditivo ... -
Dot-blot immunoassay for detection of tomato chlorosis virus and reaction of potato genotypes to virus infection
(Springer, 2021-03-10)Tomato chlorosis virus (ToCV) is a whitefly-transmitted crinivirus that causes yield losses, mainly in tomato (Solanum lycopersicum) and potato (S. tuberosum) crops. In this work, a polyclonal antiserum for detecting the ... -
