“…En Bolivia poco o nada se cultiva tomate híbrido de crecimiento indeterminado bajo condiciones de invernadero, representando una oportunidad para agricultores, que podrían introducir en su producción este tipo de cultivos, que sean rentables. Entre las ventajas que presentan el uso de variedades indeterminadas hibridas se destacan su alto vigor, uniformidad, producción, excelente calidad y tolerancia a algunas enfermedades (Jaramillo et al 2012). Por otra parte, la vida en anaquel está definida como el periodo, que el producto debería mantener un nivel de calidad predeterminado bajo condiciones específicas de almacenamiento (Shewfelt 1986).…”

Fueron evaluados 11 híbridos de tomate indeterminado de la empresa ENZA ZADEN y un testigo de la empresa SEMINIS, bajo condiciones de invernadero y laboratorio con los objetivos de: i) evaluar y seleccionar participativamente 11 nuevos híbridos de tomate indeterminado de la empresa ENZA ZADEN, por su adaptación, sus características agronómicas y de sanidad en el ciclo del cultivo, en cosecha y en pos-cosecha y ii) Implementar con agricultores emprendedores, el negocio de los tomates híbridos indeterminados seleccionados participativamente. Los resultados mostraron que las variedades con mayor número de frutos y rendimiento fueron Shanon y Afamia entre las de tipo beef (redondas) y Granadero entre las peras. Las variedades redondas presentaron un rendimiento promedio superior al de las peras. Las variedades peras presentaron un número de frutos promedio superior al de las redondas. Hubo una correlación alta y positiva entre el número de frutos y el rendimiento tanto en peras como en redondas. Las variedades con mayor peso de fruto fueron Bruni (entre las redondas) y Centenario, Granadero y (entre las peras). El peso de fruto se reduce en el tiempo en forma lineal para todas las variedades excepto Corleone. La variedad redonda con mayor firmeza de fruto fue Shannon. No hubo diferencia en firmeza entre las peras. La firmeza de fruto reduce en el tiempo en forma lineal para las variedades Bruni, Elpida, Hechicero, Rally, Centenario, Corleone y reduce en forma lineal pero incrementa en forma cuadrática para las variedades Maradona y Shannon. Las variedades que redujeron la firmeza de sus frutos a menor velocidad fueron Corleone, Centenario y Afamia. Las variedades con menor pH fueron Afamia (entre las redondas) y Centenario y Granadero (entre las peras). El pH incrementa en el tiempo en forma lineal en todas las variedades. Las variedades con mayor contenido de Grados Brix fueron Hechicero, Afamia, Granadero, Elpida, Rally, Maradona y Sebatina (entre las redondas) y Corleone (entre las peras). El contenido de Grados Brix incrementa en forma lineal en el tiempo en todas las variedades. Existieron correlaciones significativas altas y positivas entre Grados Brix y pH; y entre peso y firmeza de fruto. Se logró la selección participativa de las variedades Elpida, Rally (redondas), Centenario y Policarpo (Peras), que ahora son las que se están produciendo comercialmente en los invernaderos de EL Paso en Cochabamba. © 2016.

“…In Colombia, a total of 347,636 tons of tomato were produced during 2017, representing one of the most cultivable vegetable crops in the country. However, this crop is highly susceptible to biotic and abiotic stresses, which result in an increase in production costs [26,28]. Fusarium wilt is currently a disease of major significance throughout the country.…”

“…The seeds of tomato hybrids used in Colombia are imported, and there is no information about Fol races present in the country. Tomato producers located in departments with high yields, such as Cundinamarca, Boyacá, Antioquia, and Caldas, use tomato seeds with no information about resistance to local populations of Fol [28]. The lack of knowledge about the causal agent of the vascular wilting symptoms affecting tomato crops makes the development of adequate management practices difficult.…”

Characterization of Pathogenic and Nonpathogenic Fusarium oxysporum Isolates Associated with Commercial Tomato Crops in the Andean Region of Colombia

et al. 2020

In Colombia, tomato production under protected conditions represents an important economic contribution to the agricultural sector. Fusarium wilt diseases, caused by pathogenic formae speciales of the soil-borne fungus Fusarium oxysporum Schltdl., cause significant yield losses in tomatoes throughout the world. Investigation of the F. oxysporum–tomato pathosystem in Colombia is required to develop appropriate alternative disease management. In this study, 120 fungal isolates were obtained from four different departments in the Central Andean Region in Colombia from tomato crops with symptoms of wilt disease. A molecular characterization of the fungal isolates was performed using the SIX1, SIX3, and SIX4 effector genes of Fusarium oxysporum f. sp. lycopersici W.C. Snyder & H.N. Hansen (Fol). Additionally, we developed a new specific marker to distinguish between Fusarium oxysporum f. sp. radicis-lycopersici Jarvis & Shoemaker (Forl) and Fol isolates. Furthermore, a phylogenetic analysis using the Translation Elongation Factor 1-alpha (EF1a) gene was performed with the collected isolates. Two isolates (named Fol59 and Fol-UDC10) were identified as Fol race 2, four isolates were identified as Forl, six isolates were identified as F. solani, and most of the isolates were grouped within the F. oxysporum species complex. The phylogenetic tree of EF1a showed that most of the isolates could potentially correspond to nonpathogenic strains of F. oxysporum. Additional pathogenicity assays carried out with Fol59 and Fol-UDC10 confirmed that both isolates were highly virulent strains. This study represents a contribution to the understanding of the local interaction between tomatoes and F. oxysporum in Colombia.

“…Many of the techniques used to analyze the caliber and morphology of tomato fruits are still based on the reliability of a visual and tactile analysis, which do not guarantee to carry out a quality process in optimal conditions and may present significant errors. The size, morphology and maturity classification are the most used for tomato fruit [3].…”

This paper describes the development of estimation algorithms for the size and shape of tomato fruits, implemented on a portable electronic system used in greenhouses, with the purpose to classify and collect of tomatoes milano and chonto type. The algorithms were implemented in a Raspberry-Pi embedded card through the use of free software libraries (Python, OpenCV, Pillow and Scikit-Image) and using a Pi-Camera for real-time processing, taking into account the parameters of classification defined in national (NTC1103-1) and international (USDA) standards. Were applied classification algorithms based on Canny to estimate the size of the tomato fruit, as well as techniques based on estimation of the eccentricity and statistical moments descriptors for the measurement of the shape, which were evaluated with a performance superior to 90 %. Classification techniques of tomato shape and size using artificial vision overcame subjective techniques of visual and tactile type classification carried out by farmers and specialized technicians.
