Characterization of physiological races of Phytophthora infestans (Mont.) de Bary in lulo (Solanum quitoense Lam.)
description Lulo blight is one of the most important problems of this crop in Colombia, present in all departments of the country that grow it, with an incidence of 100%. Due to the ignorance of the complexity of physiological races of Phytophthora infestans in cultivated lulo (Solanum quitoense), collections were evaluated from potato (Solanum tuberosum sub species andigena), tree tomato (Cyphomandra betacea) , tomato (Solanum lycopersicum) and water cucumber or sweet cucumber (Solanum muricatum) obtained in various lulo producing departments of Colombia. The results obtained on the virulence of the pathogen on 11 potato differentials (along with the variety Tuquerreña) indicated that for lulo there are 15 physiological races with, according to octal nomenclature, 4211 being the most frequent with 23.25% frequency and virulence factors of 0, 4, 8 and 11, collected in the municipalities of Rionegro and Urrao, followed by 2211, 0213, 0231 and 1112 with four virulence factors and a frequency of 2.32% each, collected in the municipalities Oporapa, Jardín, Jardín and Santa Rosa de Cabal, respectively. Similarly, we found 3223 with virulence factors 1, 2, 4, 7, 10, and 11 in potato, 4421 with factors 0, 3, 7, 10 and 11 collected from the tomato and 4000 with virulence factor 0 in cucumber; indicating that the pathogen from potato is the most complex.

El desconocimiento en la complejidad de las razas fisiológicas dePhytophthora infestans en cultivos de lulo (Solanum quitoense) se evaluaron colectas provenientes de este cultivo, papa (Solanum tuberosum sub especie andigena), tomate de árbol (Cyphomandra betacea), tomate de mesa (Solanum lycopersicum) y pepino de agua o pepino dulce (Solanum muricatum), obtenidas en varios departamentos de Colombia productores de lulo. Los resultados obtenidos sobre la virulencia del patógeno realizada sobre 11 diferenciales de papa (junto con la variedad Tuquerreña), indican para el lulo, la presencia de 15 razas fisiológicas, según nomenclatura octal siendo la más frecuente la 4211 con 23,25% de frecuencia y los factores de virulencia 0, 4, 8 y 11, colectada en los municipios de Urrao y Rionegro seguida de la 2211, 0213, 0231 y 1112 con 4 factores de virulencia y una frecuencia de 2,32% cada una, colectadas en los municipios de Oporapa, Jardín y Santa Rosa de Cabal, respectivamente. Igualmente, se encontró la raza 3223 con los factores de virulencia 1, 2, 4, 7, 10, y 11 procedente de papa, la raza 4421 con los factores 0, 3, 7, 10 y 11 colectada en tomate de mesa y la 4.000 con el factor de virulencia 0, procedente de pepino, lo cual indica que el patógeno procedente de papa, es el más complejo.    Lulo 2018-11-06T20:41:28Z 2018-11-06T20:41:28Z 2012 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://revista.corpoica.org.co/index.php/revista/article/view/235 10.21930/rcta.vol13_num1_art:235 http://hdl.handle.net/20.500.12324/33892 reponame:Biblioteca Digital Agropecuaria de Colombia repourl:https://repository.agrosavia.co instname:Corporación colombiana de investigación agropecuaria AGROSAVIA spa http://revista.corpoica.org.co/index.php/revista/article/view/235/240 application/pdf Antioquia Colombia Corporación Colombiana de Investigación Agropecuaria (Agrosavia) Rionegro (Colombia) Corpoica Ciencia y Tecnología Agropecuaria; Vol 13 No 1 (2012); 13-20 Corpoica Ciencia y Tecnología Agropecuaria; Vol. 13 Núm. 1 (2012); 13-20 revista Corpoica Ciência e Tecnologia Agropecuária; v. 13 n. 1 (2012); 13-20 2500-5308 0122-8706 10.21930/rcta.vol13-num1
